Incompatible changes:

• Python, Windows: the --[no]incompatible_windows_escape_python_args is no longer supported. (It was flipped to true in Bazel 0.27.0)
• --incompatible_use_native_patch is enabled by default
• Windows: --incompatible_windows_bashless_run_command is now true by default, meaning "bazel run //foo:bin" will run the binary as a subprocess of the Bazel client. (When the flag is false, the binary is executed as a subprocess of Bash.)
• Windows: --incompatible_windows_native_test_wrapper is enabled by default

New features:

• Genrule now supports cmd_bash, cmd_ps, cmd_bat attributes. More details at https://docs.bazel.build/versions/master/be/general.html#genrule.c md
• config_setting can now check multiple values on "--foo=firstVal --foo=secondVal ..."-style flags
• tags: use --experimental_allow_tags_propagation flag to propagate tags to the action's execution requirements from targets. Such tags should start with: no-, requires-, supports-, block-, disable-, cpu:. See #8830 for details.
• Users can now get generated def file from cc_library via "def_file" output group on Windows.
• Platform-specific bazelrc: with --enable_platform_specific_config you can enable flags in bazelrc according to your host platform.
• tags: use --experimental_allow_tags_propagation flag to propagate tags to the action's execution requirements from cc_library or cc_binary targets. Such tags should start with: no-, requires-, supports-, block-, disable-, cpu:. See #8830 for details.
• tags: use --experimental_allow_tags_propagation flag to propagate tags to the action's execution requirements from java targets. Such tags should start with: no-, requires-, supports-, block-, disable-, cpu:. See #8830 for details.

Important changes:

• Bazel Android builds now use aapt2 by default. To revert to aapt, set --android_aapt=aapt.
• Make either --subcommands or --verbose_failures imply --materialize_param_files
• Bazel Android builds now use aapt2 by default. To revert to aapt, set `--an... RELNOTES: None
• by default all remote connections considered to be via gRPC with TLS enabled, unless other specified. To disable TLS use grpc:// prefix for you endpoints. All remote connections via gRPC affected - --remote_cache, --remote_executor or --bes_backend. http cache/executor is not affected. See #8061 for details.
• cc_* rules support non-transitive defines through a 'local_defines' attribute.
• Enable incompatible_disallow_rule_execution_platform_constraints_allowed by default (bazelbuild#8136).
• incompatible_disallow_split_empty_separator is enabled by default
• Fixed Android build issues with aapt2 on Windows. See the GitHub issue for more information.
• --incompatible_disable_static_cc_toolchains has been flipped. See bazelbuild#8546.

• The flag incompatible_disallow_hashing_frozen_mutables is enabled (bazelbuild#7800)
• maven_jar and maven_server now disallow using plain HTTP URLs without a specified checksum. If you are still using maven_jar, consider migrating to [rules_jvm_external](https://github.com/bazelbuild/rules_jvm_ext ernal) for transitive dependency management. See #8607 for more information.
• Added sha256 and sha256_src attributes to maven_jar. Please consider migrating to SHA-256 as SHA-1 has been deemed cryptographically insecure (https://shattered.io). Or, use [rules_jvm_external](https://github.com/bazelbuild/rules_jvm_ext ernal) to manage your transitive Maven dependencies with artifact pinning and SHA-256 verification support.
• introducing per-target exec_properties
• Bazel now supports ThinLTO builds on Linux for Clang versions >= 6.0. ThinLTO can be enabled through --features=thin_lto

Important changes:

• rule_test: fix Bazel 0.27 regression ("tags" attribute was ingored, bazelbuild#8723
• Adds --incompatible_enable_execution_transition, which enables incremental migration of host attributes to exec attributes.
• objc_proto_library rule has been deleted from Bazel.
• repository_ctx.read is no longer restricted to files in the repository contructed.
• tags 'no-remote', 'no-cache', 'no-remote-cache', 'no-remote-exec', 'no-sandbox' are propagated now to the actions from targets when '--ncompatible_allow_tags_propagation' flag set to true. See #8830.
• Adds flag --//tools/build_defs/pkg:incompatible_no_build_defs_pkg. This flag turns off the rules //tools/build_defs/pkg:{pkg_deb, pkg_rpm, pkg_tar}.
• The Android NDK is now integrated with toolchains. To use them, pass the --extra_toolchains=@androidndk//:all flag or register them in your WORKSPACE with register_toolchains("@androidndk//:all").
• Stdout and stderr are checked to determine if output is going to a terminal. --is_stderr_atty is deprecated and --isatty is undeprecated.
• --incompatible_load_proto_rules_from_bzl was added to forbid loading the native proto rules directly. See more on tracking issue #8922
• Docker Sandbox now respects remote_default_platform_properties
• pkg_deb, pkg_rpm & pkg_tar deprecation plan announced in the documentation.
• The new java_tools release:
  • fixes bazelbuild#8614
  • exposes a new toolchain @java_tools//:prebuilt_toolchain which is using all the pre-built tools, including singlejar and ijar, even on remote execution. This toolchain should be used only when host and execution platform are the same, otherwise the binaries will not work on the execution platform.
• java_common.compile supports specifying annotation_processor_additional_inputs and annotation_processor_additional_outputs for the Java compilation action for supporting annotation processors that consume or produce artifacts. Fixes #6415
• There is now documentation on optimizing Android app build performance. Read it at https://docs.bazel.build/versions/0.29.0/android-build-performance .html
• Execution log now respects --remote_default_platform_properties
• Include a link to the relevant documenation on transitive Python version errors.
• New incompatible flag --incompatible_disable_target_provider_fields removes the ability (in Starlark) to access a target's providers via the field syntax (for example, ctx.attr.dep.my_provider). The provider-key syntax should be used instead (for example, ctx.attr.dep[MyProvider]). See bazelbuild#9014 for details.
• A new platform exec_properties is added to replace remote_execution_properties.
• Added --incompatible_load_python_rules_from_bzl, which will be flipped in Bazel 1.0. See bazelbuild#9006.
• add --break_build_on_parallel_dex2oat_failure to shortcut tests on dex2oat errors

• Turn on --experimental_build_setting_api by default for starlark build settings (see https://docs.bazel.build/versions/master/skylark/config.html#user- defined-build-settings for more info)
• @bazel_tools//tools/jdk:toolchain_java10 and @bazel_tools//tools/jdk:toolchain_java11 are now available to enable java 10, respectively java 11 language level support.
• The command parameter of the actions.run_shell() function will be restricted to only accept strings (and not string sequences). This check is attached to flag --incompatible_run_shell_command_string. One may migrate by using the arguments parameter of actions.run() instead. See bazelbuild#5903 for more info.

Incompatible changes:

• --incompatible_disable_objc_provider_resources no longer has effect. Use of deprecated resource fields on the Objc provider is now disallowed regardless of this flag.
• deleted deprecated --experimental-remote-retry* flags, please use --remote_retries instead
• flipped --incompatible_list_based_execution_strategy_selection flag to be true by default. See bazelbuild#7480 for details.
• Octal integer literals in Starlark are required to start with "Oo".
• The "native" module is no longer available in BUILD files, all its members can be accessed directly as global symbols. This can be temporarily reverted by providing --incompatible_disallow_native_in_build_file=false as a flag to Blaze.
• The "native" module is no longer available in BUILD files, all its members can be accessed directly as global symbols. This can be temporarily reverted by providing --incompatible_disallow_native_in_build_file=false as a flag to Blaze.

• cleanup that affects user provided apple frameworks is now enabled by default. See bazelbuild#7944 for more info.
• Python rules now determine the Python runtime using toolchains rather than --python_top and --python_path, which are deprecated. See #7899 for information on declaring Python toolchains and migrating your code. As a side-benefit, this addresses #4815 (incorrect interpreter version used) on non-Windows platforms. Note however that some builds break due to getting the version they asked for -- consider setting python_version = "PY2" on Python 2 targets and --host_force_python=PY2 if any Python 2 targets are used in the host configuration. You can temporarily opt out of this change with --incompatible_use_python_toolchains=false.
• Depsets can't be iterated over unless they're converted to lists using the .to_list() method. Use --incompatible_depset_is_not_iterable=false to temporarily restore the previous behaviour.

New features:

• Bash, runfiles: the copy-pasted init code of the Bash runfiles library is now shorter, see tools/bash/runfiles/runfiles.bash. The rlocation() implementation is the same.
• Bash, runfiles: the copy-pasted init code of the Bash runfiles library is now shorter, see tools/bash/runfiles/runfiles.bash. The rlocation() implementation is the same.
• Bash, runfiles: the copy-pasted init code of the Bash runfiles library is now shorter, see tools/bash/runfiles/runfiles.bash. To use the new init code, you need Bazel 0.27 or newer. The old (longer) init code still works.

• The outputs parameter of the rule() function is deprecated and attached to flag --incompatible_no_rule_outputs_param. Migrate rules to use OutputGroupInfo or attr.output instead. See bazelbuild#7977 for more info.
• The --incompatible_disable_objc_library_resources flag is being removed. Please remove it from your configs as it otherwise will fail the build.
• Add a generic additional_linker_inputs attribute on cc_binary rules.
• Windows, C++ autoconfigure: BAZEL_VC and BAZEL_VS may now have quotes, so if you set these envvars' values in cmd.exe via TAB-completion then you no longer need to remove the surrounding quotes.
• pkg_deb has new attributes: config and templates that can be used for integration with debconf
• Allow cc_import() of a DLL with no interface library on Windows, used to document runtime dependencies.
• All host-configured Python tools that are built for the wrong Python version will now emit a warning message when they exit with non-zero status. See #7899.
• deprecated --remote_local_fallback_strategy. Use --strategy=remote,local instead. See bazelbuild#7480.
• Introduce --incompatible_disable_native_android_rules flag
• The Android desugaring actions now support a persistent worker mode for faster local build performance. Enable it with --strategy=Desugar=worker.
• --incompatible_static_name_resolution_in_build_files is now enabled by default
• --incompatible_disable_deprecated_attr_params is now enabled by default (#5818)
• Repository containing autoconfigured C++ toolchain @local_config_cc has been split in 2 - see local_config_cc_toolchains.
• --incompatible_string_join_requires_strings is now enabled by default
• Flag --incompatible_new_actions_api is enabled by dewfault (#5825)
• New flag --incompatible_disallow_empty_glob. See bazelbuild#8195
• --incompatible_no_kwargs_in_build_files is enabled by default
• Incompatible flag --incompatible_require_ctx_in_configure_features has been flipped. See bazelbuild#7793 for more information.
• BAZEL_USE_XCODE_TOOLCHAIN=1 tells Bazel not to look for Xcode to decide whether to enable toolchains for Apple rules, but to assume Xcode is available. Can be also used when building on Darwin and no C++ or ObjC is being built, so there is no need to detect Xcode.
• Android desugaring actions now use persistent workers by default. This has been measured to provide up to 20% reduction in build times. To disable it, use the --strategy=Desugar=sandboxed flag. See bazelbuild#8342 and bazelbuild#8427 for more details on local build speed optimization for Android apps.
• Fixed an issue with Android builds where --fat_apk_cpu doesn't pack all selected shared libraries from aar_import targets into the APK. See #8283.
• Turn on --experimental_starlark_config_transitions by default for starlark transitions (see https://docs.bazel.build/versions/master/skylark/config.html#user- defined-transitions for more info)
• Turn on --experimental_build_setting_api by default for starlark build settings (see https://docs.bazel.build/versions/master/skylark/config.html#user- defined-build-settings for more info)
• Incompatible flag --incompatible_dont_enable_host_nonhost_crosstool_features has been flipped. See bazelbuild#7407 for more information.
• Added support for Android NDK 19 and 20.
• Flip --incompatible_no_support_tools_in_action_inputs
• --remote_executor, --remote_cache or --bes_backend=someurl.com would be treated as grpcs://someurl.com, if the --incompatible_tls_enabled_removed flag enabled. See bazelbuild#8061 for details.
• Add new options --cs_fdo_absolute_path= to support the absolute path profile for LLVM's context-sensitive FDO.
• When --incompatible_strict_action_env is enabled, the default PATH now includes /usr/local/bin.
• Turn on --experimental_build_setting_api by default for starlark build settings (see https://docs.bazel.build/versions/master/skylark/config.html#user- defined-build-settings for more info)

     Allow Starlark rules to be able to use the `exec_compatible_with`

Incompatible changes

• --incompatible_windows_escape_jvm_flags is enabled by default, and removed.

• --incompatible_windows_style_arg_escaping is enabled by default.

• --incompatible_no_output_attr_default is enabled by default.

• --incompatible_depset_union is enabled by default.

• --incompatible_disable_genrule_cc_toolchain_dependency removed

• --Incompatible_disallow_rule_execution_platform_constraints_allowed: When enabled, disallows the use of the execution_platform_constraints_allowed attribute when defining new rules.

• --incompatible_disable_objc_provider_resources is now enabled by default.

Apple

• The --ios_multi_cpus, --watchos_cpus, --macos_cpus and --tvos_cpus are now additive. This means that you can now split the --ios_multi_cpus=arm64,armv7 into --ios_multi_cpus=arm64 and --ios_multi_cpus=armv7.

• Add --incompatible_objc_framework_cleanup to control whether to enable some objc framework cleanup that changes the API. Specifically, the cleanup changes the objc provider API pertaining to frameworks. This change is expected to be transparent to most users unless they write their own Starlark rules to handle frameworks. See bazelbuild#7594 for details.

• objc_library does not support resource attributes any more. Please read #7594 for more info.

Android

• Android resource conflicts will no longer be reported between a strong attr resource and a weak attr resource, if the weak attr does not have format specified.

C++

• [Allow debugging C++ features logic](https://github.com/bazelbuild/bazel/commit/53156db1e30fe7197889c3cbc8d1321ff9b85143

• Add new options --cs_fdo_instrument and --cs_fdo_profile to support LLVM's context-sensitive FDO (CSFDO).

• Bazel C++ compile/link Starlark API. Can be used with experimental flag --experimental_cc_skylark_api_enabled_packages.

• cc_toolchain.static_runtime_lib and cc_toolchain.dynamic_runtime_lib are now exposed to Starlark.

• C++ Starlark API for compilation and linking is no longer whitelisted

• Incompatible flag --incompatible_make_thinlto_command_lines_standalone has been added. See bazelbuild#6791 for details.

• Feature disable_whole_archive_for_static_lib has been added to allow turning off legacy_whole_archive for individual targets. bazelbuild#7362

Python

• Fixed an issue where some py_runtimes were incompatible with using --build_python_zip (#5104).

Starlark

• The flag --incompatible_restrict_named_params is added. Buildifier will soon be updated to automatically fix this in your code.

• The flag --incompatible_no_kwargs_in_build_files is added. It fixes a bug where the **kwarg notation was allowed in BUILD files.

• The flag --incompatible_static_name_resolution_in_build_files is added. This fixes a bug where invalid code was silently accepted.

• The flag --incompatible_disallow_old_octal_notation is added. It removes a deprecated notation for octal numbers. Buildifier can update your code automatically.

• struct.to_proto() can now convert dictionaries into proto3 text message.

• The glob function has a new argument allow_empty. When set to False (this will be the default in the future), the glob fails when it doesn't match anything. Please explicitly set allow_empty = True to the globs that need it.

Windows

• Windows, Python: the new --incompatible_windows_escape_python_args flag (false by default) builds py_binary and py_test targets with correct command line argument escaping. Similar to bazelbuild#7486 but for py_* rules.

Other changes

• cquery supports --output=build

• Generated Go protobufs now depend on //net/proto2/go:proto_gendeps instead of //net/proto2/go:proto

• Added --incompatible_remove_binary_profile to disable the old binary profiles. Instead use the JSON profile format: https://docs.bazel.build/versions/master/skylark/performance.html#json-profile

• Introducing --execution_log_binary_file and --execution_log_json_file that output a stable sorted execution log. They will offer a stable replacement to --experimental_execution_log_file.

• New platform_mappings ability to allow gradual flag to platforms/toolchains migration. See also bazelbuild#6426

• Added support for compiling against fully qualified R classes from aar_import dependencies.

• --tls_enabled flag is deprecated. Please provide grpcs as a scheme in the URLs if TLS should be used for a remote connection.

Community

• Alex Eagle gave a talk at ng-conf: The Bazel Opt-in Preview is Here!

• The latest release of rules_haskell includes many new improvements, including an initial Windows support.

• The latest Buildifier release includes Windows binaries, as well as a JSON output for diagnostics.

• Natan Silnitsky gave the talk How to successfully migrate to Bazel from Maven or Gradle at the Java Eastern Europe Conference.

Incompatible changes:

• (Starlark rules) The legacy "py" provider can no longer be passed to or produced by native Python rules; use [PyInfo](https://docs.bazel.build/versions/master/skylark/lib/PyIn fo.html) instead. See #7298 for more information.
• (Python rules) The default_python_version attribute of the py_binary and py_test rules has been renamed to python_version. Also, the --force_python flag has been renamed to --python_version. See #7308 for more information.
• (Python rules) The python version now changes to whatever version is specified in a py_binary or py_test's python_version attribute, instead of being forced to the value set by a command line flag. You can temporarily revert this change with --incompatible_allow_python_version_transitions=false. See #7307 for more information.
• --incompatible_disable_third_party_license_checking` is enabled by default
• Introduced --incompatible_use_python_toolchains, which supersedes --python_top/--python_path. See #7899 and #7375 for more information.
• Python 3 is now the default Python version (for py_binary and py_test targets that don't specify the python_version attribute). Targets that are built for Python 3 will no longer have their output put in a separate -py3 directory; instead there is now a separate -py2 directory for Python 2 targets. See #7359 and #7593 for more information.
• objc_library resource attributes are now disabled by default. Please migrate them to data instead. See bazelbuild#7594 for more info.
• Flip --incompatible_windows_escape_jvm_flags to true. See bazelbuild#7486

New features:

• genrules now support a $(RULEDIR) variable that resolves to the directory where the outputs of the rule are put.
• Added --incompatible_windows_native_test_wrapper flag: enables using the Bash-less test wrapper on Windows. (No-op on other platforms.)

Important changes:

• incompatible_use_jdk11_as_host_javabase: makes JDK 11 the default --host_javabase for remote jdk (bazelbuild#7219)
• Makes genquery somepath output deterministic.
• Tristate attributes of native rules now reject True/False (use 1/0)
• Rollback of "Tristate attributes of native rules now reject True/False (use 1/0)"
• Tristate attributes of native rules now reject True/False (use 1/0)
• Added -incompatible_do_not_split_linking_cmdline flag. See #7670
• Tristate attributes of native rules now temporarily accept True/False again
• --incompatible_disable_legacy_crosstool_fields has been flipped (bazelbuild#6861) --incompatible_disable_expand_if_all_available_in_flag_set has been flipped (bazelbuild#7008)
• --incompatible_disable_legacy_crosstool_fields has been flipped (bazelbuild#6861) `--incompatible_disable_expand_if_all_available_in_flag_set... RELNOTES: None.
• --incompatible_no_transitive_loads is enabled by default.
• Makes TreeArtifact deterministic.
• --incompatible_no_transitive_loads is enabled by default.
• Android NDK C++ toolchain is now configured in Starlark. This should be a backwards compatible change, but in case of bugs blame unknown commit.
• --incompatible_disable_legacy_crosstool_fields has been flipped (bazelbuild#6861) --incompatible_disable_expand_if_all_available_in_flag_set has been flipped (bazelbuild#7008)
• --incompatible_no_transitive_loads is enabled by default.
• --incompatible_bzl_disallow_load_after_statement is enabled
• Added --incompatible_require_ctx_in_configure_features, see bazelbuild#7793 for details.
• Flag --incompatible_merge_genfiles_directory is flipped. This removes the directory bazel-genfiles in favor of bazel-bin.
• previously deprecated flag --experimental_remote_spawn_cache was removed
• --incompatible_disallow_load_labels_to_cross_package_boundaries is enabled by default
• Fix an issue where the Android resource processor did not surface errors from aapt2 compile and link actions.
• --incompatible_no_attr_license is enabled by default
• --incompatible_disable_crosstool_file has been flipped (bazelbuild#7320)
• A new flag --incompatible_string_join_requires_strings is introduced. The sequence argument of string.join must contain only string elements.
• --incompatible_symlinked_sandbox_expands_tree_artifacts_in_runfile s_tree has been flipped
• Incompatible flag --incompatible_disable_legacy_cc_provider has been flipped (see bazelbuild#7036 for details).
• Don't drop the analysis cache when the same --define flag is set multiple times and the last value is the same (e.g. if the current invocation was run with "--define foo=bar" and the previous one was run with "--define foo=baz --define foo=bar").
• The --incompatible_disable_genrule_cc_toolchain_dependency flag has been flipped (see bazelbuild#6867 for details).
• Incompatible change --incompatible_remove_cpu_and_compiler_attributes_from_cc_toolcha in has been flipped (see bazelbuild#7075 for details).
• --noexperimental_java_coverage is a no-op flag.
• --experimental_java_coverage/--incompatible_java_coverage flag was removed. See #7425.
• incompatible_use_toolchain_providers_in_java_common: pass JavaToolchainInfo and JavaRuntimeInfo providers to java_common APIs instead of configured targets (bazelbuild#7186.)
• --incompatible_remote_symlinks has been flipped. The remote caching and execution protocol will now represent symlinks in outputs as such. See bazelbuild#7917 for more details.
• Bazel is now ~20MiB smaller, from unbundling the Android rules' runtime dependencies.

Incompatible changes:

• Added --incompatible_py3_is_default to test switching the default Python version to PY3 for py_binary/py_test targets that do not specify a version. See #7359.
• //tools/cmd_line_differ has been renamed to //tools/aquery_differ & can now compare (in addition to command lines) inputs of actions given 2 aquery results.
• java_(mutable_|)proto_library: removed strict_deps attribute.
• The flag --incompatible_list_based_execution_strategy_selection was added and is used to ease the migration to the new style of specifying execution strategy selection and fallback behavior. The documentation for this flag is here: bazelbuild#7480
• Added --incompatible_py2_outputs_are_suffixed, for switching the bazel-bin symlink to point to Python 3 outputs instead of Python 2 outputs. See #7593.

New features:

• Make actions.args() object chainable.
• Added --incompatible_windows_style_arg_escaping flag: enables correct subprocess argument escaping on Windows. (No-op on other platforms.)
• Added --incompatible_windows_escape_jvm_flags flag: enables correct java_binary.jvm_flags and java_test.jvm_flags tokenization and escaping on Windows. (No-op on other platforms.)

Important changes:

• Allow running aquery against the current state of Skyframe
• Added support for the "navigation" resource directory to Android resource processing in Bazel. This is used by the Navigation Architecture Component.
• --incompatible_disable_runtimes_filegroups was flipped (bazelbuild#6942)
• Incompatible flag --incompatible_linkopts_in_user_link_flags has been flipped (bazelbuild#6826)
• Incompatible flag --incompatible_dont_emit_static_libgcc has been flipped (bazelbuild#6825)
• --incompatible_disallow_filetype is enabled by default.
• Fixed issue where exceptions and stacktraces were silently swallowed in the Android resource processing pipeline.
• --incompatible_disable_expand_if_all_available_in_flag_set has been flipped (bazelbuild#7008)
• --incompatible_disallow_dict_plus is enabled by default
• Adds --incompatible_disable_objc_library_resources to disable resource attributes in objc_library. Please migrate these attributes to data instead.
• --incompatible_disallow_old_style_args_add is enabled by default.
• Using the native module in BUILD files is deprecated. It will be forbidden with --incompatible_disallow_native_in_build_file.
• (Python rules) PyRuntimeInfo is exposed to Starlark, making it possible for Starlark rules to depend on or imitate py_runtime. The files attribute of py_runtime is no longer mandatory.
• incompatible_use_toolchain_providers_in_java_common: pass JavaToolchainInfo and JavaRuntimeInfo providers to java_common APIs instead of configured targetshttps://github.com/bazelbuild/issues/7186.
• is_using_fission crosstool variable is now exposed in all compile actions when fission is active (it used to be exposed only for linking actions).
• incompatible_use_toolchain_providers_in_java_common: pass JavaToolchainInfo and JavaRuntimeInfo providers to java_common APIs instead of configured targetshttps://github.com/bazelbuild/issues/7186.
• py_runtime gains a python_version attribute for specifying whether it represents a Python 2 or 3 interpreter.
• --incompatible_java_coverage is enabled by default.
• Starlark rules can safely declare attributes named "licenses"
• When using --incompatible_list_based_execution_strategy_selection, Bazel will use remote execution by default (if you specify --remote_executor), otherwise persistent workers (if the action supports it), otherwise sandboxed local execution (if the action and platform supports it) and at last unsandboxed local execution. The flags --spawn_strategy and --strategy continue to work as before - this only sets new defaults for the case where you don't specify these flags.
• Set default value of --incompatible_remap_main_repo to true.
• Set default value of --incompatible_remap_main_repo to true.

Release 0.23.0 (2019-02-26)

Baseline: 441fd75d0047f8a998d784c557736ab9075db893

Incompatible changes:

• //src:bazel uses the minimal embedded JDK, if you want to avoid the extra steps of minimizing the JDK, use //src:bazel-dev instead.
• //src:bazel uses the minimal embedded JDK, if you want to avoid the extra steps of building bazel with the minimized JDK, use //src:bazel-dev instead.
• The default value of --host_platform and --platforms will be changed to not be dependent on the configuration. This means that setting --cpu or --host_cpu will not affect the target or host platform.
• Toolchain resolution for cc rules is now enabled via an incompatible flag, --incompatible_enable_cc_toolchain_resolution. The previous flag, --enabled_toolchain_types, is deprecated and will be removed.
• java_(mutable_|)proto_library: removed strict_deps attribute.
• Python rules will soon reject the legacy "py" struct provider (preview by enabling --incompatible_disallow_legacy_py_provider). Upgrade rules to use PyInfo instead. See #7298.
• java_(mutable_|)proto_library: removed strict_deps attribute.
• Two changes to native Python rules: 1) default_python_version and --force_python are deprecated; use python_version and --python_version respectively instead. You can preview the removal of the deprecated names with --incompatible_remove_old_python_version_api. See #7308. 2) The version flag will no longer override the declared version of a py_binary or py_test target. You can preview this new behavior with --incompatible_allow_python_version_transitions. See #7307.

Important changes:

• There is a new flag available --experimental_java_common_create_provider_enabled_packages that acts as a whitelist for usages of java_common.create_provider. The constructor will be deprecated in Bazel 0.23.
• [#7024] Allow chaining of the same function type in aquery.
• Introduces --local_{ram,cpu}_resources, which will take the place of --local_resources.
• [#6930] Add documentation for the aquery command.
• Incompatible flag --incompatible_dont_emit_static_libgcc has been flipped (bazelbuild#6825)
• Incompatible flag --incompatible_linkopts_in_user_link_flags has been flipped (bazelbuild#6826)
• Flag --incompatible_range_type is removed.
• Flag --incompatible_disallow_slash_operator is removed.
• Flag --incompatible_disallow_conflicting_providers is removed.
• --incompatible_disallow_data_transition is now enabled by default
• Allow inclusion of param files in aquery output
• [#6985] Add test to verify aquery's behavior for Cpp action templates.
• --incompatible_require_feature_configuration_for_pic was flipped (bazelbuild#7007).
• Also ignore module-info.class in multi-version Jars
• objc_framework has been deleted. Please refer to apple_dynamic_framework_import and apple_static_framework_import rules available in [rules_apple](https://github.com/bazelbuild/rules_apple/blob/maste r/doc/rules-general.md)
• --test_sharding_strategy=experimental_heuristic is no more
• objc_bundle_library has been removed. Please migrate to rules_apple's [apple_resource_bundle](https://github.com/bazelbuild/rules_apple/ blob/master/doc/rules-resources.md#apple_resource_bundle).
• You can now use the attribute aapt_version or the flag --android_aapt to pick the aapt version for android_local_test tests
• In --keep_going mode, Bazel now correctly returns a non-zero exit code when encountering a package loading error during target pattern parsing of patterns like "//foo:all" and "//foo/...".
• The default value for --incompatible_strict_action_env has been flipped to 'false' again, as we discovered breakages for local execution users. We'll need some more time to figure out the best way to make this work for local and remote execution. Follow bazelbuild#7026 for more details.
• Locally-executed spawns tagged "no-cache" no longer upload their outputs to the remote cache.
• Introduces --host_compiler flag to allow setting a compiler for host compilation when --host_crosstool_top is specified.
• --incompatible_expand_directories is enabled by default
• [aquery] Handle the case of aspect-on-aspect.
• Fixed a longstanding bug in the http remote cache where the value passed to --remote_timeout would be interpreted as milliseconds instead of seconds.
• Enable --incompatible_use_jdk10_as_host_javabase by default, see bazelbuild#6661
• Add --incompatible_use_jdk11_as_host_javabase: makes JDK 11 the default --host_javabase for remote jdk (bazelbuild#7219)
• Highlight TreeArtifact in aquery text output.
• Locally-executed spawns tagged "no-cache" no longer upload their outputs to the remote cache.
• java_common APIs now accept JavaToolchainInfo and JavaRuntimeInfo instead of configured targets for java_toolchain and java_runtime
• cc_common.create_cc_toolchain_config_info is stable and available for production use
• incompatible_use_toolchain_providers_in_java_common: pass JavaToolchainInfo and JavaRuntimeInfo providers to java_common APIs instead of configured targets (bazelbuild#7186)
• --incompatible_strict_argument_ordering is enabled by default.
• Bazel now supports reading cache hits from a repository cache, even if it doesn't have write access to the cache.
• Adding arm64e to OSX CROSSTOOL.
• Ignore package-level licenses on config_setting.
• Add an optional output_source_jar parameter to java_common.compile
• --incompatible_disable_objc_provider_resources is now enabled by default. This disables ObjcProvider's fields related to resource processing.
• Explicitly set https.protocols and exclude TLSv1.3.
• Bazel now validates that JAVA_HOME points to a valid JDK and falls back to auto-detection by looking up the path of javac.
• Upgrade the embedded JDK version to 11.0.2.
• Added --incompatible_disable_crosstool_file (bazelbuild#7320)
• --incompatible_disable_objc_provider_resources is now enabled by default. This disables ObjcProvider's fields related to resource processing.
• --incompatible_disable_tools_defaults_package has been flipped.
• For tests that do not generate a test.xml, Bazel now uses a separate action to generate one; this results in minor differences in the generated test.xml, and makes the generation more reliable overall.
• incompatible_generate_javacommon_source_jar: java_common.compile now always generates a source jar, see bazelbuild#5824.
• New incompatible flag --incompatible_disallow_struct_provider_syntax removes the ability for rule implementation functions to return struct. Such functions should return a list of providers instead. Migration tracking: bazelbuild#7347

Breaking changes

• --incompatible_string_is_not_iterable

Upcoming changes

This release is a migration window for the following changes.

• --incompatible_disallow_data_transition
• --incompatible_dont_emit_static_libgcc
• --incompatible_linkopts_in_user_link_flags
• --incompatible_disable_legacy_crosstool_fields
• --incompatible_use_aapt2_by_default
• --incompatible_disable_runtimes_filegroups
• --incompatible_disable_legacy_cc_provider
• --incompatible_require_feature_configuration_for_pic

General Changes

• https://docs.bazel.build now supports versioned documentation. Use the selector at the top of the navigation bar to switch between documentation for different Bazel releases.

• set projectId in all PublishBuildToolEventStreamRequest

Android

• mobile-install now works with aapt2. Try it out with bazel mobile-install --android_aapt=aapt2 //my:target

• Fixed issues with mobile-install v1 when deploying to Android 9 Pie devices. bazelbuild#6814

• Fixed issue where error messages from Android manifest merging actions were not fully propagated.

• New incompatible change flag --incompatible_use_aapt2_by_default for defaulting to aapt2 in Android builds has been added. To build with aapt2 today, pass the flag --incompatible_use_aapt2_by_default=true or --android_aapt=aapt2, or set the aapt_version to aapt2 on your android_binary or android_local_test target.

• Fixed mobile-install v1 error when installing an app with native libraries onto an Android 9 (Pie) device. See bazelbuild/examples#77

• Fixed a mobile-install bug where arm64-v8a libraries were not deployed correctly on arm64 devices. This was done by enabling incremental native lib deployment by default. A previously undocumented --android_incremental_native_libs flag is removed, and is now the regular behavior. See bazelbuild#2239

Apple

• The objc_bundle rule has been removed. Please migrate to rules_apple's [apple_bundle_import](https://github.com/bazelbuild/rules_apple/bl ob/master/doc/rules-resources.md#apple_bundle_import).

• The apple_stub_binary rule has been deleted.

• The --xbinary_fdo option that passes xbinary profiles has been added.

C++

• cc_toolchain.(static|dynamic)_runtime_libs attributes are now optional

Packaging

• build_tar.py in tools/build_defs/pkg now supports a JSON manifest that can be used to add paths that have symbols that can't be specified via the command line

Query

• Filtering of inputs, outputs, and mnemonic filtering have been added to aquery.

• The aquery and cquery query2 tests have been open-sourced.

• The Bazel query how-to recommends ":*" instead of ":all", because "all" might be the name of a target.

Testing

• The --runs_per_test has been placed in the TESTING documentation category.

• A a clarifying message has been added to test case summary output when all test cases pass but the target fails.

Baseline: cb9b2afbba3f8d3a1db8bf68e65d06f1b36902f5

Cherry picks:

   + 12b96466ee0d6ab83f7d4cd24be110bb5021281d:
     Windows, test wrapper: rename the associated flag
   + 7fc967c4d6435de2bb4e34aac00ca2e499f55fca:
     Use a fixed thread pool in ByteStreamBuildEventArtifactUploader
   + 798b9a989aa793655d29504edb5fb85f3143db84:
     Add --build_event_upload_max_threads option
   + dbe05df23ccf4c919379e0294e0701fd3f66739c:
     Update the version of  skylib bundled in the distfile

Incompatible changes:

• The --experimental_stl command line option is removed.
• aquery defaults to human readable output format.

New features:

• repository_ctx.download and repository_ctx.download_and_extract now return a struct.
• Android Databinding v2 can be enabled with --experimental_android_databinding_v2.

Important changes:

• The deprecated and unmaintained Docker rules in tools/build_defs/docker were removed. Please use https://github.com/bazelbuild/rules_docker instead.
• The new --upload_query_output_using_bep query/cquery/aquery flag causes query outputs to be uploaded via BEP.
• New incompatible flag --incompatible_strict_argument_ordering
• --strict_android_deps and --strict_java_deps were renamed to --experimental_strict_java_deps
• config_settings that select on "compiler" value instead of values = {"compiler" : "x"} should use flag_values = {"@bazel_tools//tools/cpp:compiler": "x"}.
• The new --upload_query_output_using_bep query/cquery/aquery flag causes query outputs to be uploaded via BEP.
• Turn on --incompatible_disable_sysroot_from_configuration
• We revamped our Android with Bazel tutorial! Check it out [here](https://docs.bazel.build/versions/master/tutorial/android-a pp.html).
• --incompatible_disallow_slash_operator is now on by default
• Enable --experimental_check_desugar_deps by default. This flag rules out several types of invalid Android builds at compile-time.
• The --max_config_changes_to_show option lists the names of options which have changed and thus caused the analysis cache to be dropped.
• The --experimental_strict_action_env option has been renamed to --incompatible_strict_action_env and is now on by default. This means Bazel will no longer use the client's PATH and LD_LIBRARY_PATH environmental variables in the default action environment. If the old behavior is desired, pass --action_env=PATH and --action_env=LD_LIBRARY_PATH. --noincompatible_strict_action_env will also temporarily restore the old behavior. However, as --action_env is a more general and explicit way to pass client environmental variables into actions, --noincompatible_strict_action_env will eventually be deprecated and removed. See #6648 for more details.
• XCRUNWRAPPER_LABEL has been removed. If you used this value before, please use @bazel_tools//tools/objc:xcrunwrapper instead.
• --incompatible_static_name_resolution is no unable by default
• We will phase out --genrule_strategy in favor of --strategy=Genrule= (for genrules) or --spawn_strategy= (for all actions).
• --incompatible_package_name_is_a_function is now enabled by default
• Dynamic execution is now available with --experimental_spawn_strategy. Dynamic execution allows a build action to run locally and remotely simultaneously, and Bazel picks the fastest action. This provides the best of both worlds: faster clean builds than pure local builds, and faster incremental builds than pure remote builds.
• --incompatible_package_name_is_a_function is now enabled by default
• New incompatible flag --incompatible_merge_genfiles_directory
• grpc log now logs updateActionResult
• CppConfiguration doesn't do package loading anymore. That means:
  • it's no longer needed to have C++ toolchain available when building non-C++ projects
  • bazel will not analyze C++ toolchain when not needed -> speedup ~2s on bazel startup when C++ rules using hermetic toolchain are not loaded
• --incompatible_package_name_is_a_fu...

     flag."
   + f7e5aef145c33968f658eb2260e25630dc41cc67:

     cc_toolchain_suite.
   + d2920e32ec7f3f8551a693d33c17b19f1b802145:

• The --prune_cpp_modules command line option is not supported anymore.
• the --experimental_prune_cpp_input_discovery command line option is not supported anymore.

New features:

• Added support for Android NDK r18.

Important changes:

• The 'default' parameter of attr.output and attr.output_list is removed. This is controlled by --incompatible_no_output_attr_default
• A number of platform-related Starlark APIs which were previously marked "experimental" are now disabled by default, and may be enabled via --experimental_platforms_api
• Make legacy-test-support ("legacy_test-") from android_sdk_repository neverlink. The legacy test support libraries shouldn't be built into test binaries. To make them available at runtime, developers should declare them via uses-library: https://developer.android.com/training/testing/set-up-project#andr oid-test-base
• query remote server Capabilities (per REAPI v2)
• CppRules: All cc_toolchains depended on from cc_toolchain_suite.toolchains are now analyzed when not using platforms in order to select the right cc_toolchain.
• removed obsolete --explicit_jre_deps flag.
• Incompatible flag --incompatible_disable_legacy_cpp_toolchain_skylark_api was flipped.
• Improve error messaging when unsupport proguard options are specified at the library level.
• Incompatible flag --incompatible_disable_legacy_cpp_toolchain_skylark_api was flipped.
• Incompatible flag --incompatible_disable_legacy_cpp_toolchain_skylark_api was flipped.
• The --incompatible_disable_late_bound_option_defaults flag has been flipped (#6384)
• Incompatible flag --incompatible_disable_legacy_flags_cc_toolchain_api was flipped (#6434)
• Fixed issue where ctx.resolve_command created conflicting intermediate files when resolve_command was called multiple times within the same rule invocation with a long command attribute.
• Incompatible flag --incompatible_disable_cc_configuration_make_variables was flipped (#6381)
• If the --javabase flag is unset, it Bazel locates a JDK using the JAVA_HOME environment variable and searching the PATH. If no JDK is found --javabase will be empty, and builds targeting Java will not be supported. Previously Bazel would fall back to using the embedded JDK as a --javabase, but this is no longer default behaviour. A JDK should be explicitly installed instead to enable Java development
• Bazel will now shut down when idle for 5 minutes and the system is low on RAM (linux only).
• CROSSTOOL file is now read from the package of cc_toolchain, not from the package of cc_toolchain_suite. This is not expected to break anybody since cc_toolchain_suite and cc_toolchain are commonly in the same package.
• All overrides of Starlark's ctx.new_file function are now deprecated. Try the --incompatible_new_actions_api flag to ensure your code is forward-compatible.
• --incompatible_disable_cc_toolchain_label_from_crosstool_proto was flipped.
• Introduce --(no)shutdown_on_low_sys_mem startup flag to toggle idle low-memory shutdown, disabled by default.
• --incompatible_disable_cc_toolchain_label_from_crosstool_proto was flipped.
• --incompatible_disable_cc_toolchain_label_from_crosstool_proto was flipped.
• CppRules: All cc_toolchains depended on from cc_toolchain_suite.toolchains are now analyzed when not using platforms in order to select the right cc_toolchain.
• The function attr.license is deprecated and will be removed. It can be disabled now with --incompatible_no_attr_license.
• range() function now returns a lazy value (--incompatible_range_type is now set by default).
• The code coverage report now includes the actual paths to header files instead of the ugly, Bazel generated, virtual includes path.
• --incompatible_disallow_conflicting_providers has been switched to true
• Add new flag --incompatible_disable_systool_from_configration to disable loading the systool from CppConfiguration.
• Add new flag --incompatible_disable_sysroot_from_configuration to disable loading the systool from CppConfiguration.
• Sorting remote Platform properties for remote execution. May affect cache keys!
• Use different server log files per Bazel server process; java.log is now a symlink to the latest log.

The Bazel team is happy to announce a new version of Bazel, Bazel 0.19.

This document lists the major changes since Bazel 0.18.

General changes

• The --incompatible_expand_directories flag will automatically expand directories in command lines. Design doc: https://docs.google.com/document/d/11agWFiOUiz2htBLj6swPTob5z78TrCxm8DQE4uJLOwM

• The --loading_phase_threads flag now defaults to auto (not 200, as was previously the case), which at the moment corresponds to the number of CPUs. This is appropriate for most users. However, if your sources reside on a network file system, increasing this value may yield better analysis-time performance when disk caches are cold.

Android

• Fixed missing debug symbols when building native code with --compilation_mode=dbg that target Android ARM architectures by adding the -g flag.

C++

• Added --incompatible_disable_legacy_flags_cc_toolchain_api to deprecate legacy cc_toolchain Starlark API for legacy CROSSTOOL fields. Tracking issue is #6434. Migration docs are on the bazel website.

• Runfiles in cc_test: the C++ runfiles library (@bazel_tools//tools/cpp/runfiles) can now create Runfiles objects for tests. See //tools/cpp/runfiles/runfiles_src.h (in the Bazel source tree) for documentation.

• :cc_binary link action no longer hardcodes -static-libgcc for toolchains that support embedded runtimes (guarded by --experimental_dont_emit_static_libgcc temporarily).

• The flag --experimental_enable_cc_configuration_make_variables is removed, use --incompatible_disable_cc_configuration_make_variables instead.

Java

• If the --javabase flag is unset, Bazel locates a JDK using the JAVA_HOME environment variable and searching the PATH. If no JDK is found --javabase will be empty, and builds targeting Java will not be supported. Previously Bazel would fall back to using the embedded JDK as a --javabase, but this is no longer default behaviour. A JDK should be explicitly installed instead to enable Java development.

Code Coverage

• LcovMerger was renamed to CoverageOutputGenerator.

• Faster coverage collection for gcc compiled C++ code can now be tested by enabling it with --experimental_cc_coverage.

Other Changes

• Add --apple_compiler and --apple_grte_top options. These provide the equivalent of --compiler / --grte_top for the toolchain configured in --apple_crosstool_top.

• There is now a same_pkg_direct_rdeps query function. See the query documentation for more details.

• Propagating remote errors to the user even if --verbose_failures=false is set.

• Add number of configured targets to analysis phase status output.

• Bazel will now check stderr instead of stdout to decide if it is outputting to a terminal. --isatty is deprecated, use --is_stderr_atty instead.

Future Changes

• None of the C++ related incompatible flags mentioned in the 0.18 release were flipped, they will be flipped in the next release (0.20). We have created tracking issues for all the relevant incompatible flags:

  • --incompatible_disable_late_bound_option_defaults: #6384
  • --incompatible_disable_depset_in_cc_user_flags: #6383
  • --incompatible_disable_cc_toolchain_label_from_crosstool_proto: #6382
  • --incompatible_disable_cc_configuration_make_variables: #6381
  • --incompatible_disable_legacy_cpp_toolchain_skylark_api: #6380
  • incompatible_disable_legacy_flags_cc_toolchain_api: #6434

• In the 0.20 release the flags --incompatible_remove_native_git_repository and --incompatible_remove_native_http_archive will be turned on.

     Temporarily restore processing of workspace-wide tools/bazel.rc

General changes

• New bazelrc file list. If you need to keep both the old and new lists of .rc files active concurrently to support multiple versions of Bazel, you can import the old file location into the new list using try-import. This imports a file if it exists and silently exits if it does not. You can use this method to account for a user file that may or may not exist

• .bazelignore is now fully functional.

• The startup flag --host_javabase has been renamed to --server_javabase to avoid confusion with the build flag --host_javabase.

Android

• The Android resource processing pipeline now supports persistence via worker processes. Enable it with --persistent_android_resource_processor. We have observed a 50% increase in build speed for clean local builds and up to 150% increase in build speed for incremental local builds.

C++

• In-memory package //tools/defaults has been removed (controlled by --incompatible_disable_tools_defaults_package flag). Please see migration instructions and migrate soon, the flag will be flipped in Bazel 0.19, and the legacy behavior will be removed in Bazel 0.20.

• Late bound option defaults (typical example was the --compiler flag, when it was not specified, it’s value was computed using the CROSSTOOL) are removed (controlled by --incompatible_disable_late_bound_option_defaults flag). Please see migration instructions and migrate soon, the flag will be flipped in Bazel 0.19, and the legacy behavior will be removed in Bazel 0.20.

• Depsets are no longer accepted in user_compile_flags and user_link_flags in the C++ toolchain API (controlled by --incompatible_disable_depset_in_cc_user_flags flag) affects C++ users. Please see migration instructions and migrate soon, the flag will be flipped in Bazel 0.19, and the legacy behavior will be removed in Bazel 0.20.

• CROSSTOOL is no longer consulted when selecting C++ toolchain (controlled by --incompatible_disable_cc_toolchain_label_from_crosstool_proto flag). Please see migration instructions and migrate soon, the flag will be flipped in Bazel 0.19, and the legacy behavior will be removed in Bazel 0.20.

• You can now use toolchain_identifier attribute on cc_toolchain to pair it with CROSSTOOL toolchain.

• C++ specific Make variables are no longer passed from the CppConfiguration, but from the C++ toolchain (controlled by --incompatible_disable_cc_configuration_make_variables flag). Please see migration instructions and migrate soon, the flag will be flipped in Bazel 0.19, and the legacy behavior will be removed in Bazel 0.20.

• Skylark api accessing C++ toolchain in ctx.fragments.cpp is removed (controlled by --incompatible_disable_legacy_cpp_toolchain_skylark_api flag). Please migrate soon, the flag will be flipped in Bazel 0.19, and the legacy behavior will be removed in Bazel 0.20.

• cc_binary link action no longer hardcodes -static-libgcc for toolchains that support embedded runtimes (guarded by --experimental_dont_emit_static_libgcc temporarily). Proper deprecation using --incompatible flags will follow.

Java

• Future versions of Bazel will require a locally installed JDK for Java development. Previously Bazel would fall back to using the embedded --server_javabase if no JDK as available. Pass --incompatible_never_use_embedded_jdk_for_javabase to disable the legacy behaviour.

• --javacopt= no longer affects compilations of tools that are executed during the build; use --host_javacopt= to change javac flags in the host configuration.

Objective C

• objc_library now supports the module_name attribute.

Skylark

• Adds --incompatible_expand_directories to automatically expand directories in skylark command lines. Design doc: https://docs.google.com/document/d/11agWFiOUiz2htBLj6swPTob5z78TrCxm8DQE4uJLOwM

• Support fileset expansion in ctx.actions.args(). Controlled by --incompatible_expand_directories.

Windows

• --windows_exe_launcher is deprecated, this flag will be removed soon. Please make sure you are not using it.

• Bazel now supports the symlink runfiles tree on Windows with --experimental_enable_runfiles flag. For more details, see this doc.

Other Changes

• A new experimental option --experimental_ui_deduplicate has been added. It causes the UI to attempt to deduplicate messages from actions to keep the console output cleaner.

• Add --modify_execution_info, a flag to customize action execution info.

• Add ExecutionInfo to aquery output for ExecutionInfoSpecifier actions.

• When computing --instrumentation_filter, end filter patterns with "[/:]" to match non-top-level packages exactly and treat top-level targets consistently.

• Added the bazel info server_log command, which obtains the main Bazel server log file path. This can help debug Bazel issues.

• aapt shrink resources now properly respect filter configurations.

Important changes:

• In the future, Bazel will expand tree artifacts in runfiles, too, which causes the sandbox to link each file individually into the sandbox directory, instead of symlinking the entire directory. In this release, the behavior is not enabled by default yet. Please try it out via --incompatible_symlinked_sandbox_expands_tree_artifacts_in_runfile s_tree and let us know if it causes issues. If everything looks good, this behavior will become the default in a following release.

Incompatible changes:

• Loading @bazel_tools//tools/build_defs/repo:git_repositories.bzl no longer works. Load @bazel_tools//tools/build_defs/repo:git.bzl instead.
• If the same artifact is generated by two distinct but identical actions, and a downstream action has both those actions' outputs in its inputs, the artifact will now appear twice in the downstream action's inputs. If this causes problems in Skylark actions, you can use the uniquify=True argument in Args.add_args.
• If the same artifact is generated by two distinct but identical actions, and a downstream action has both those actions' outputs in its inputs, the artifact will now appear twice in the downstream action's inputs. If this causes problems in Skylark actions, you can use the uniquify=True argument in Args.add_args.
• Labels in C++ rules' linkopts attribute are not expanded anymore unless they are wrapped, e.g: $(location //foo:bar)
• If the same artifact is generated by two distinct but identical actions, and a downstream action has both those actions' outputs in its inputs, the artifact will now appear twice in the downstream action's inputs. If this causes problems in Skylark actions, you can use the uniquify=True argument in Args.add_args.
• New bazelrc file list.
• Windows: when BAZEL_SH envvar is not defined and Bazel searches for a suitable bash.exe, Bazel will no longer look for Git Bash and no longer recommend installing it as a Bash implementation. See issue #5751.
• New bazelrc file list.

New features:

• The aquery command now supports --output=text.
• Java, runfiles: the Java runfiles library is now in @bazel_tools//tools/java/runfiles. The old target (@bazel_tools//tools/runfiles:java-runfiles) is deprecated and will be removed in Bazel 0.18.0.
• Java, runfiles: the Java runfiles library is now in @bazel_tools//tools/java/runfiles. The old target (@bazel_tools//tools/runfiles:java-runfiles) is deprecated and will be removed in Bazel 0.19.0 (not 0.18.0, as stated earlier).

Important changes:

• Allow @ in package names.
• Remove support for java_runtime_suite; use alias() together with select() instead.
• Python wrapper scripts for MSVC are removed.
• [JavaInfo] Outputs are merged in java_common.merge().
• Faster analysis by improved parallelization.
• --experimental_shortened_obj_file_path is removed.
• Introduce the --remote_cache_proxy flag, which allows for remote http caching to connect via a unix domain socket.
• No longer define G3_VERSION_INFO for c++ linkstamp compiles, as it was a duplicate of G3_TARGET_NAME.
• Added support for Android NDK r17. The default STL is now libc++, and support for targeting mips, mips64 and ARMv5 (armeabi) has been removed.
• Add aquery command to get analysis time information about the action graph.
• Fixed compatibility with aar_import when using aapt2. AAPT2 is now supported for Android app builds without resource shrinking. To use it, pass the --android_aapt=aapt2 flag or define android_binary.aapt_version=aapt2.
• Code coverage is collected for Java binaries invoked from sh_test.
• java_common.compile creates the native headers jar accesible via JavaInfo.outputs.native_headers.
• Deleting deprecated no-op flag --show_package_location
• The JDK shipped with Bazel was updated to JDK10.
• Rename the startup flag --host_javabase to --server_javabase to avoid confusion with the build flag --host_javabase
• newly added options --experimental_repository_hash_file and --experimental_verify_repository_rules allow to verify for repositories the directory generated against pre-recorded hashes. See documentation for those options.
• Removed the gen_jars output group
• --subcommands can now take a "pretty_print" value ("--subcommands=pretty_print") to print the arguments of subcommands as a list for easier reading.
• follow-up to https://github.com/bazelbuild/bazel/commit/1ac359743176e659e9c7472 645e3142f3c44b9e8
• A rule error is now thrown if a Skylark rule implementation function returns multiple providers of the same type.
• When using Bazel's remote execution feature and Bazel has to fallback to local execution for an action, Bazel used non-sandboxed local execution until now. From this release on, you can use the new flag --remote_local_fallback_strategy= to tell Bazel which strategy to use in that case.
• Execution Log Parser can now, when printing it out, filter the log by runner type
• A rule error is now thrown if a Skylark rule implementation function returns multiple providers of the same type.
• Removed the gen_jars output group
• Removed the gen_jars output group
• Set --defer_param_files to default to true.
• Sort attribute lists in proto-form query output to fix non-deterministic genquery output.
• Replace 0/1 with False/True for testonly attribute
• bazel now supports a .bazelignore file specifying directories to be ignored; however, these directories still have to be well founded and, in particular, may not contain symlink cycles.
• Add more detailed reporting of the differences between startup options.
• update data binding to 3.2.0
• For Android incremental dexing actions, Bazel now persists its DexBuilder process across individual actions. From our benchmarks, this results in a 1.2x speedup for clean local builds.
• The standard xcode_VERSION feature now always uses exactly two components in the version, even if you specify --xcode_version with more or fewer than two.
• A rule error will be thrown if a Skylark rule implementation function returns multiple providers of the same type. Try the --incompatible_disallow_conflicting_providers flag to ensure your code is forward-compatible.
• Removed notion of FULLY_STATIC linking mode from C++ rules.
• In documentation, we've renamed Skylark into Starlark.
• Execution Log Parser can now, when printing it out, reorder the actions for easier text diffs
• Linkstamps are no longer recompiled after server restart.
• Use VanillaJavaBuilder and disable header compilation in toolchain_hostjdk8. The default toolchain will soon drop compatibility with JDK 8. Using a JDK 8 host_javabase will only be supported when using 'VanillaJavaBuilder' (which does not support Error Prone, Strict Java Deps, or reduced classpaths) and with header compilation disabled.
• In the future, Bazel will expand tree artifacts in runfiles, too, which causes the sandbox to link each file individually into the sandbox directory, instead of symlinking the entire directory. In this release, the behavior is not enabled by default yet. Please try it out via --incompatible_symlinked_sandbox_expands_tree_artifacts_in_runfile s_tree and let us know if it causes issues. If everything looks good, this behavior will become the default in a following release.

This release is a patch release that contains fixes for several serious regressions that were found after the release of Bazel 0.16.0.

In particular this release resolves the following issues:

• Bazel crashes with a StackOverflowError on Windows (See #5730)
• Bazel requires a locally installed JDK and does not fall back to the embedded JDK (See #5744)
• Bazel fails to build for Homebrew on macOS El Capitan (See #5777)
• A regression in apple_static_library (See #5683)

Please watch our blog for a more detailed release announcement.

     jdk: use parallel old gc and disable compact strings

Incompatible changes:

• The $(ANDROID_CPU) Make variable is not available anymore. Use $(TARGET_CPU) after an Android configuration transition instead.
• The $(JAVA_TRANSLATIONS) Make variable is not supported anymore.
• Skylark structs (using struct()) may no longer have to_json and to_proto overridden.
• The mobile-install --skylark_incremental_res flag is no longer available, use the --skylark flag instead.

New features:

• android_local_test now takes advantage of Robolectric's binary resource processing which allows for faster tests.
• Allow @ in package names.

Important changes:

• Option --glibc is removed, toolchain selection relies solely on --cpu and --compiler options.
• Build support for enabling cross binary FDO optimization.
• The --distdir option is no longer experimental. This option allows to specify additional directories to look for files before trying to fetch them from the network. Files from any of the distdirs are only used if a checksum for the file is specified and both, the filename and the checksum, match.
• Java coverage works now with multiple jobs.
• Flip default value of --experimental_shortened_obj_file_path to true, Bazel now generates short object file path by default.
• New rules for importing Android dependencies: aar_import_external and aar_maven_import_external. aar_import_external enables specifying external AAR dependencies using a list of HTTP URLs for the artifact. aar_maven_import_external enables specifying external AAR dependencies using the artifact coordinate and a list of server URLs.
• The BAZEL_JAVAC_OPTS environment variable allows arguments, e.g., "-J-Xmx2g", may be passed to the javac compiler during bootstrap build. This is helpful if your system chooses too small of a max heap size for the Java compiler during the bootstrap build.
• --noexpand_configs_in_place is deprecated.
• A tool to parse the Bazel execution log.
• Support for LIPO has been fully removed.
• Remove support for --discard_actions_after_execution.
• Add --materialize_param_files flag to write parameter files even when actions are executed remotely.
• Windows default system bazelrc is read from the user's ProgramData if present.
• --[no]allow_undefined_configs no longer exists, passing undefined configs is an error.
• In remote caching we limit the number of open TCP connections to 100 by default. The number can be adjusted by specifying the --remote_max_connections flag.

Incompatible changes:

• Bazel now always runs binaries in with "bazel run" in interactive mode. The "--nodirect_run" command line option is now a no-op.
• "bazel run --noas_test" is not supported anymore.
• Indentation on the first line of a file was previously ignored. This is now fixed.

New features:

• C++,runfiles: to access data-dependencies (runfiles) in C++ programs, use the runfiles library built into Bazel. For usage info, see https://github.com/bazelbuild/bazel/blob/master/tools/cpp/runfiles /runfiles.h

Important changes:

• Bazel now allows almost all 7-bit ASCII characters in labels.
• Remove vestigial java_plugin.data attribute
• Bazel supports including select Java 8 APIs into Android apps targeting pre-Nougat Android devices with --experimental_desugar_java8_libs
• Flag --incompatible_disable_glob_tracking is removed.
• SkyQuery's rbuildfiles now returns targets corresponding to broken packages.
• Introduce build support for providing cache prefetch hints.
• Update the skylark DefaultInfo documentation to spell out runfiles, data_runfiles and default_runfiles
• An internal action for symlinking runfiles will use Command instead of a Spawns. This should have no functional chages; the only user visible consequence should be that the internal action is no longer be included in statistics when calculating processes count.
• --batch is deprecated
• execution strategies line no longer handles differently the case where all processes have the same strategy.
• The --experimental_remote_spawn_cache flag is now enabled by default, and remote caching no longer needs --*_strategy=remote flags (it will fail if they are specified).
• android_binary.aapt_version='aapt2' now supports en_XA and ar_XB
• Added --apple_enable_auto_dsym_dbg flag.
• non_propagated_deps has been removed from objc_library and apple_binary.
• For Android projects, Bazel now supports building fonts as resources. See https://developer.android.com/guide/topics/ui/look-and-feel/fonts-in-xml for more information on the feature.
• With --incompatible_no_support_tools_in_action_inputs enabled, Skylark action inputs are no longer scanned for tools. Move any such inputs to the newly introduced 'tools' attribute.

Incompatible changes:

• Add --incompatible_disallow_legacy_javainfo flag.
• Added flag --incompatible_disallow_old_style_args_add to help migrate from args.add() to args.add_all() / args.add_joined() where appropriate.

New features:

• Bash,runfiles: use the new platform-independent library in @bazel_tools//tools/bash/runfiles to access runfiles (data-dependencies). See https://github.com/bazelbuild/bazel/blob/master/tools/bash/runfile s/runfiles.bash for usage information.
• TemplateVariableInfo can now be constructed from Skylark.
• The java_host_runtime_alias rule is now implemented in Java.

Important changes:

• Flip default value of --experimental_shortened_obj_file_path to true, Bazel now generates short object file path by default.
• Introduce fdo_profile rule that allows architecture-sensitive specification of fdo profiles.
• canonicalize-flags no longer reorders the flags
• CppRules: optional_compiler_flag was removed from CROSSTOOL, use features instead.
• Labels of the form ////foo are disallowed.
• The / operator is deprecated in favor of // (floor integer division). Try the --incompatible_disallow_slash_operator flag to ensure your code is forward-compatible.
• Flip default value of --experimental_shortened_obj_file_path to true, Bazel now generates short object file path by default.
• Exposed "mnemonic" and "env" fields on skylark "Action" objects.
• Removed flag --incompatible_disallow_toplevel_if_statement.
• Remove vestigial 'deps' and 'data' attributes from proto_lang_toolchain
• Args objects (ctx.actions.args()) have new methods add_all() and add_joined() for building command lines using depsets.
• FileType is deprecated and will be removed soon. Try the --incompatible_disallow_filetype flag to ensure your code is forward-compatible.
• Introduce absolute_path_profile attribute that allows fdo_profile to accept absolute paths.
• Support two-arg overloads for ctx.actions.args (eg. args.add("--foo", val))
• Introduce 'tools' attribute to ctx.actions.run.
• Fixed error message for proguard_apply_dictionary.
• "bazel run" now lets one run interactive binaries. The BUILD_WORKSPACE_DIRECTORY and BUILD_WORKING_DIRECTORY environment variables indicate the working directory and the workspace root of the Bazel invocation. Tests are provided with an approximation of the official test environment.
• repository rules are no longer restricted to return None.
• Add --high_priority_workers flag.
• CppRules: Feature configuration can be created from Skylark
• Adds new-style JavaInfo provider constructor.
• Make java_common.compile now uses java_toolchain javacopts by default; explicitly retrieving them using java_common.default_javac_opts is unnecessary.
• CppRules: C++ command lines and env variables for C++ actions can be retrieved from feature configuration.
• Skylark rule definitions may advertise providers that targets of the rule must propagate.
• Bazel now supports running actions inside Docker containers. To use this feature, run "bazel build --spawn_strategy=docker --experimental_docker_image=myimage:latest".
• Remote execution works for Windows binaries with launchers.
• Fixing start/end lib expansion for linking. There were many cases where archive files were still being used with toolchains that support start/end lib. This change consolidates the places that make that decision so they can be more consistent.
• Add support for reporting an error if android_test.binary_under_test contains incompatible versions of deps
• We replaced the --experimental_local_disk_cache and --experimental_local_disk_cache_path flags into a single --disk_cache flag. Additionally, Bazel now tries to create the disk cache directory if it doesn't exist.
• Save Blaze memory by not storing LinkerInput objects in LinkCommandLine
• In the JavaInfo created by java_common.create_provider now includes both direct and transitive arguments in transitive_compile_time_jars and transitive_runtime_jars
• Allow --worker_max_instances to take MnemonicName=value to specify max for each worker.
• Allow java_toolchain.header_compiler to be an arbitrary executable

• Remove the default content of the global bazelrc.

• In int() function, do not auto-detect base if input starts with '0'.

• Users can now pass --experimental_shortened_obj_file_path=true to have a shorter object file path, the object file paths (and all other related paths) will be constructed as following: If there's no two or more source files with the same base name:

  /<target_package_path>/_objs/<target_name>/<source_base _name>. otherwise:

  /<target_package_path>/_objs/<target_name>/N/<source_ba se_name>. N = the file?s order among the source files with the same basename, starts from 0.

Incompatible changes:

• In order to access the template variables $(JAVA) and $(JAVABASE), @bazel_tools//tools/jdk:current_java_runtime needs to be added to the toolchains= attribute from now on.

Important changes:

• The --remote_rest_cache flag now respects --remote_timeout.
• --experimental_java_coverage is available for testing.
• The deprecated builtin set is no longer allowed even from within unexecuted code in bzl files. It's temporarily possible to use --incompatible_disallow_uncalled_set_constructor=false if this change causes incompatibility issues.
• Linkstamping is now a separate and full-blown CppCompileAction, it's no longer a part of linking command.
• Using +, | or .union on depsets is now deprecated. Please use the new constructor instead (see https://docs.bazel.build/versions/master/skylark/depsets.html).
• config_feature_flag's default_value is optional. It is only an error to have a config_feature_flag with no default_value if that config_feature_flag has not been set in the configuration it is being evaluated in.
• --[no]keep_incrementality_data is gone, replaced by the enum-valued --incremental_state_retention_strategy
• Linkstamping is now a separate and full-blown CppCompileAction, it's no longer a part of linking command.

• Set build jobs equivalent to number of logical processors by default. Should improve build times significantly.
• Added --(no)expand_test_suites flag.
• Rename --keep_incrementality_data to --track_incremental_state

Incompatible changes:

• The deprecated set constructor is removed, along with the migration flag --incompatible_disallow_set_constructor. It is still temporarily allowed to refer to set from within unexecuted code.
• The flag --incompatible_disallow_set_constructor is no longer available, the deprecated set constructor is not available anymore.
• The path to the JVM executable is not accessible anymore as ctx.{fragments,host_fragments}.jvm.java_executable. Use JavaRuntimeInfo.java_executable_exec_path instead.

• Add --experimental_android_resource_cycle_shrinking option to allow for more aggressive code and resource shrinking.

Important changes:

• Late-bound attributes are exposed to skylark. This is a new API (configuration_field()) to depend on certain configuration-defined targets from skylark rules.
• Document interaction between test_suite and target exclusions
• AAR manifest files will come from the processed resource APK if it exists. RELNOTES: None for Blaze users.
• Document interaction between test_suite and target exclusions

• in the Label() function, relative_to_caller_repository is now deprecated.
• java_tests no complain when use_testrunner is explicitly set to 1 and main_class is set.
• Bazel's default hash function was changed from MD5 to SHA256. In particular, this affects users of remote caching and execution, as all hashes will be SHA256 by default.
• Remove redirects for domains be.bazel.build and cr.bazel.build from the source for docs.bazel.build (because those subdomains don't resolve here; they resolve to bazel.build, which has the redirects for them)
• First argument of 'load' must be a label. Path syntax is removed. (label should start with '//' or ':').
• Document startup option --host_javabase
• The --host_platform and --platform flags are no longer experimental.

Incompatible changes:

• ctx.fragments.apple.{xcode_version,ios_minimum_os} is not supported anymore. The same information is accessible through the target @bazel_tools//tools/osx:current_xcode_config: point an implicit attribute to it (i.e. attr.label(default=Label("@bazel_tools//tools/osx:current_xcode_co nfig")) then use ctx.attr._xcode_config[apple_common].XcodeVersionConfig].
• ctx.fragments.apple.minimum_os_for_platform_type is not supported anymore.

• --javabase= and --host_javabase= are not supported anymore. If you need this functionality java_runtime_suite(name="suite", default=":runtime") java_runtime(name="runtime", java_home=) is an alternative.
• The flag --incompatible_descriptive_string_representations is no longer available, old style string representations of objects are not supported anymore.
• The flag --incompatible_disallow_set_constructor is no longer available, the deprecated set constructor is not available anymore.

• the target_apple_env and apple_host_system_env methods on ctx.fragments.apple are not supported anymore. The same information is accessible through apple_common.target_apple_env and apple_common.apple_host_system_env . They need the Xcode configuration as an argument, which can be obtained by declaring an implicit dependency on it (i.e. attr.label(default=Label("@bazel_tools//tools/osx:current_xcode_co nfig")) and then calling e.g. apple_common.apple_host_system_env(ctx.attr._xcode_config[apple_co mmon.XcodeVersionConfig]).
• C++ toolchain identifiers are not in the name of the output directory anymore.
• Selecting on "xcode_version" and "{ios,tvos,macos,watchos}sdk_version" is not supported anymore. What was config_setting(values={"$FOO_version": $VALUE}) is now config_setting(flag_values={"@bazel_tools//tools/osx:$FOO_version flag": $VALUE}).
• Selecting on "xcode_version" and "{ios,tvos,macos,watchos}sdk_version" is not supported anymore. What was config_setting(values={"$FOO_version": $VALUE}) is now config_setting(flag_values={"@bazel_tools//tools/osx:$FOO_version flag": $VALUE}).

New features:

• runfiles, sh: Shell scripts may now depend on //src/tools/runfiles:runfiles_sh_lib and source runfiles.sh. The script defines the rlocation function which returns runfile paths on every platform.
• In addition to $(location), Bazel now also supports $(rootpath) to obtain the root-relative path (i.e., for runfiles locations), and $(execpath) to obtain the exec path (i.e., for build-time locations)

Important changes:

• android_binary now supports custom debug keys via the debug_key attribute.
• Updated Android proguard to 5.3.3. It now works with android-24+.
• --experimental_use_parallel_android_resource_processing and --experimental_android_use_nocompress_extensions_on_apk are removed. These features are fully rolled out.

• Improve --config logging when --announce_rc is present.
• Document interaction between test_suite and target exclusions
• Replace version numbers for Bazel installers with "" (because this will change often)
• Published command lines should have improved lists of effective options.
• --incremental_dexing_binary_types has been removed. All builds are supported by incremental dexing (modulo proguard and some blacklisted dx flags).
• Document --host_javabase, --host_java_toolchain

     Windows,bootstrapping: fix build_windows_jni.sh

Incompatible changes:

• The --output=location flag to 'bazel query' cannot be used with query expressions that involve the 'buildfiles' or 'loadfiles' operators. This also applies to 'genquery' rules.
• Operators for equality, comparison, 'in' and 'not in' are no longer associative, e.g. x < y < z is now a syntax error. Before, it was parsed as: (x < y) < z.
• In strings, octal sequences greater than \377 are now forbidden (e.g. "\600"). Previously, Blaze had the same behavior as Python 2, where "\450" == "\050".
• Using tabulation for identation is now fobidden in .bzl files
• load is now a language keyword, it cannot be used as an identifier
• lvalues must have define at least one variable (i.e. we forbid [] = f()).
• Fixed a bug whereby multiple load() statements could appear on the same line
• -extra_checks:off is no longer supported; use -XepDisableAllChecks instead
• java_common.java_toolchain_attr is removed. Depend on the java_toolchain_alias() rule to accomplish the same thing.
• cc_common.cc_toolchain_attr and java_common.java_runtime_attr are not supported anymore and were replaced with the cc_toolchain_alias() and java_runtime_alias() rules.
• Noop flag --deprecated_generate_xcode_project deleted.
• Objects in Skylark are converted to strings in a more descriptive and less harmful way (they don't leak information that shouldn't be accessed by Skylark code, e.g. nondeterministic memory addresses of objects).
• set is deprecated in BUILD and .bzl files, please use depset instead. Ordering names have also been changed, please use "default", "postorder", "preorder", and "topological" instead of "stable", "compile", "naive_link", and "link" correspondingly.
• Integer overflow (on signed 32 bit numbers) in BUILD/bzl files is an error.
• Keyword-only syntax in a function definition is now forbidden e.g. def foo(a, *, b) or def foo(a, *b, c)
• --incompatible_comprehension_variables_do_not_leak defaults to "true." Iteration variable becomes inaccessible after a list/dict comprehension.
• @bazel_tools//tools/build_defs/docker:docker.bzl is no longer available, please see https://github.com/bazelbuild/rules_docker.

New features:

• Zipped LLVM profiles are now supported.
• LIPO maps to ThinLTO for LLVM builds.
• Change to handle LLVM FDO zipped profile contents correctly.
• Do not disable fully dynamic linking with ThinLTO when invoked via LIPO options.
• There is now a 'siblings' query function. See the query documentation for more details.
• Added the print_action command, which outputs the actions needed to build a given target in the form of an ExtraActionSummary proto in text format.
• android_binary now supports proguard_apply_dictionary to specify a custom dictionary to use for choosing names to obfuscate classes and members to.

Important changes:

• Windows: bazel clean --expunge works
• First argument of 'load' should be a label. Path syntax is deprecated (label should start with '//' or ':').
• Octal prefix '0' is deprecated in favor of '0o' (use 0o777 instead of 0777).
• The extension_safe attribute of apple_binary no longer validates transitive dependencies are compiled against extension_safe APIs.
• Parentheses around the tuple are now mandatory in [a for b in c if 1, 2]
• Adjust the thresholds for --test_verbose_timeout_warnings so that it can recommending timeout increases and won't recommend timeouts that are too close to the actual timeout.
• Iterating on a depset object is deprecated. If you need an iterable, call the .to_list() method first.
• Bazel now uses tools from action_configs in Crosstool by default (as oposed to using top level tools).
• Incremental dexing errors on combination of --multidex=off and either --main-dex-list or --minimal-main-dex.

• The Build Event Protocol's File.uri field is now properly encoded according to RFC2396.
• Deprecated: Using the android_library.deps attribute to implicitly export targets to dependent rules. If your code is using this feature, Bazel will raise a warning. To fix, please use android_library.exports to explicitly specify exported targets. Run with --experimental_allow_android_library_deps_without_srcs=false to ensure forward compatibility when this feature is removed in a future release.
• java_common.create_provider is now supported with creating ijars by default. This introduces incompatibilities for existing users. Please set use_ijar=False if you don't want to use ijars.
• Tests can now write files to TEST_UNDECLARED_OUTPUTS_DIR and TEST_UNDECLARED_OUTPUTS_ANNOTATIONS_DIR and these will be reflected under bazel-testlogs.

Incompatible changes:

• The --output=location flag to 'bazel query' cannot be used with query expressions that involve the 'buildfiles' or 'loadfiles' operators. This also applies to 'genquery' rules.
• Operators for equality, comparison, 'in' and 'not in' are no longer associative, e.g. x < y < z is now a syntax error. Before, it was parsed as: (x < y) < z.
• In strings, octal sequences greater than \377 are now forbidden (e.g. "\600"). Previously, Blaze had the same behavior as Python 2, where "\450" == "\050".
• Using tabulation for identation is now fobidden in .bzl files
• load is now a language keyword, it cannot be used as an identifier
• lvalues must have define at least one variable (i.e. we forbid [] = f()).
• Fixed a bug whereby multiple load() statements could appear on the same line
• -extra_checks:off is no longer supported; use -XepDisableAllChecks instead
• java_common.java_toolchain_attr is removed. Depend on the java_toolchain_alias() rule to accomplish the same thing.

New features:

• Zipped LLVM profiles are now supported.
• LIPO maps to ThinLTO for LLVM builds.
• Change to handle LLVM FDO zipped profile contents correctly.

Important changes:

• Windows: bazel clean --expunge works
• First argument of 'load' should be a label. Path syntax is deprecated (label should start with '//' or ':').
• Octal prefix '0' is deprecated in favor of '0o' (use 0o777 instead of 0777).
• The extension_safe attribute of apple_binary no longer validates transitive dependencies are compiled against extension_safe APIs.
• Parentheses around the tuple are now mandatory in [a for b in c if 1, 2]
• Adjust the thresholds for --test_verbose_timeout_warnings so that it can recommending timeout increases and won't recommend timeouts that are too close to the actual timeout.
• Iterating on a depset object is deprecated. If you need an iterable, call the .to_list() method first.
• Bazel now uses tools from action_configs in Crosstool by default (as oposed to using top level tools).
• Incremental dexing errors on combination of --multidex=off and either --main-dex-list or --minimal-main-dex.
• When using the dictionary literal syntax, it is now an error to have duplicated keys (e.g. {'ab': 3, 'ab': 5}).
• New property on android_sdk: aapt2 Choose the version of aapt on android_binary

     ce7c4deda60a307bba5f0c9421738e2a375cf44e.

Incompatible changes:

• Blaze no longer generates xcode projects. Use tulsi.bazel.build instead.

Important changes:

• Keyword-only syntax in a function definition is deprecated (e.g. def foo(a, *, b) or def foo(a, *b, c)) and will be removed in the future.
• Attempting to build an Android target without setting up android_sdk_repository will now produce a helpful error message.
• Adds a sha256 attribute to git_repository and new_git_repository. This can only be used if the remote is a public GitHub repository. It forces Bazel to download the repository as a tarball, which will often be faster and more robust than cloning it.
• Sandboxing is now enabled by default on FreeBSD (via processwrapper-sandbox).
• android_test may use manifest placeholders with 'manifest_merger = "android"'.
• load() statements should be called at the top of .bzl files, before any other statement. This convention will be enforced in the future.
• Effectively remove sysroot from CppConfiguration and allow it to use select statements.
• proto_library.strict_proto_deps no longer exists.
• Flag --explicit_jre_deps is now a noop.
• The 'legacy' Android manifest merger is deprecated. Please upgrade to the 'android' manifest merger, which is the same merger used by Gradle. https://developer.android.com/studio/build/manifest-merge.html
• Using $(CC_FLAGS) in a GenRule adds a dependency to the c++ toolchain
• add one-version enforcement to android_local_test
• Skylark support (apple_common.dotted_version(string)) for building DottedVersion objects to interface with native apple rules
• CC_FLAGS can be defined using 'cc-flags-make-variable' action_config in CROSSTOOL
• ios_framework native rule has been removed. This rule had been essentially broken for several months now; users should be using the skylark ios framework rule. https://github.com/bazelbuild/rules_apple has details.
• Clean command no longer uses boolean values for --async, --expunge, and --expunge_async options.
• Partially fixes external J2ObjC support.
• '--aspects' can occur more than once on the command line.
• --no_ prefix no longer recognized.
• Use action_config in crosstool for static library archiving, remove ar_flag.
• Added a new flag --sandbox_writable_path, which asks the sandbox to make an existing directory writable when running actions.
• bazel test now also computes a default instrumentation filter if --collect_code_coverage is enabled
• n/na
• In .bzl files, top-level if statements are deprecated and will be forbidden in the future. Move them in a function body instead (or use a conditional expression instead: x if condition else y).
• ios_device and ios_test are deprecated. Please use the new testing rules in https://github.com/bazelbuild/rules_apple instead.
• bazel query --output package now displays packages from external repository with the format "@reponame//package". Packages in the main repository continue to have the format "package".
• ctx.expand_make_variables is deprecated.
• Bazel posts links to the CAS to the BEP if remote caching / execution is enabled
• bazel info execution_root returns the corrrect directory name for the execution root.

     Adding feature for linking C Run-Time library on Windows

Incompatible changes:

• Bazel's Linux sandbox no longer mounts an empty tmpfs on /tmp, instead the existing /tmp is mounted read-write. If you prefer to have a tmpfs on /tmp for sandboxed actions for increased hermeticity, please use the flag --sandbox_tmpfs_path=/tmp.
• Converting artifacts to strings and printing them now return "File" instead of "Artifact" to be consistent with the type name.
• The return type of depset.to_list() is now a list rather than a frozen list. (Modifying the list has no effect on the depset.)
• Bazel now prints logs in single lines to java.log
• --use_dash, --dash_url and --dash_secret are removed.
• Remote repositories must define any remote repositories they themselves use (e.g., if @x//:foo depends on @y//:bar, @y must be defined in @x's WORKSPACE file).
• Remote repositories must define any remote repositories they themselves use (e.g., if @x//:foo depends on @y//:bar, @y must be defined in @x's WORKSPACE file).
• objc_xcodeproj has been removed, use tulsi.bazel.build instead.

New features:

• If grte_top is a label, it can now follow non-configurable redirects.
• Optional coverage_files attribute to cc_toolchain
• "query --output=build" now includes select()s
• Raw LLVM profiles are now supported.

Important changes:

• Automatically generate Proguard mapping when resource shrinking and Proguard are enabled.
• New rules in Bazel: proto_library, java_lite_proto_library, java_proto_library and cc_proto_library
• Activate the "dead_strip" feature if objc binary stripping is enabled.
• More stable naming scheme for lambda classes in desugared android code
• Convert --use_action_cache to a regular option
• Per-architecture dSYM binaries are now propagated by apple_binary's AppleDebugOutputsProvider.
• Avoid factory methods when desugaring stateless lambdas for Android
• desugar calls to Objects.requireNonNull(Object o) with o.getClass() for android
• Add an --copy_bridges_from_classpath argument to android desugaring tool
• Change how desugar finds desugared classes to have it working on Windows
• Evaluation of commands on TargetsBelowDirectory patterns (e.g. //foo/...) matching packages that fail to load now report more detailed error messages in keep_going mode.
• Allow to have several inputs and outputs
• Repository context's execute() function can print stdout/stderr while running. To enable, pass quiet=False.
• Bazel can now be built with a bundled version of the OpenJDK. This makes it possible to use Bazel on systems without a JDK, or where the installed JDK is too old.
• The --jobs flag now defaults to "auto", which causes Bazel to use a reasonable degree of parallelism based on the local machine's capacity.
• Bazel benchmark (perf.bazel.build) supports Java and Cpp targets.
• no factory methods generated for lambda expressions on android
• The Linux sandbox no longer changes the user to 'nobody' by default, instead the current user is used as is. The old behavior can be restored via the --sandbox_fake_username flag.
• /tmp and /dev/shm are now writable by default inside the Linux sandbox.
• Bazel can now use the process-wrapper + symlink tree based sandbox implementation in FreeBSD.
• turn on --experimental_incremental_dexing_error_on_missed_jars by default.
• All android_binarys are now signed with both Apk Signature V1 and V2. See https://source.android.com/security/apksigning/v2.html for more details.
• Windows MSVC wrappers: Not filtering warning messages anymore, use --copt=-w and --host_copt=-w to suppress them.
• A downloader bug was fixed that prevented RFC 7233 Range connection resumes from working with certain HTTP servers
• Introduces experimental android_device rule for configuring and launching Android emulators.
• For boolean flags, setting them to false using --no_<flag_name> is deprecated. Use --no<flag_name> without the underscore, or --<flag_name>=false instead.
• Add --experimental_android_compress_java_resources flag to store java resources as compressed inside the APK.
• Removed --experimental_use_jack_for_dexing and libname.jack output of android_library.
• blaze canonicalize-flags now takes a --show_warnings flag
• Changing --invocation_policy will no longer force a server restart.
• Bazel now supports Android NDK14.
• android_binary multidex should now work without additional flags.
• Use action_config in crosstool for static library archiving, remove ar_flag.
• new option for bazel canonicalize-flags, --canonicalize_policy
• Use action_config in crosstool for static library archiving, remove ar_flag.
• android_library exports_manifest now defaults to True.
• Fix select condition intersections.
• Adds a --override_repository option that takes a repository name and path. This forces Bazel to use the directory at that path for the repository. Example usage: --override_repository=foo=/home/user/gitroot/foo.
• fix idempotency issue with desugaring lambdas in interface initializers for android
• --experimental_android_use_singlejar_for_multidex is now a no-op and will eventually be removed.
• Every local_repository now requires a WORKSPACE file.
• Remove jack and jill attributes of the android_sdk rule.
• Add Skylark stubs needed to remove sysroot from CppConfiguration.
• Desugar try-with-resources so that this language feature is available to deveces with API level under 19.
• The flag --worker_max_retries was removed. The WorkerSpawnStrategy no longer retries execution of failed Spawns, the reason being that this just masks compiler bugs and isn't done for any other execution strategy either.
• Bazel will no longer gracefully restart workers that crashed / quit, instead this triggers a build failure.
• All java resources are now compressed in android_binary APKs by default.
• All java resources are now compressed in android_binary APKs by default.
• android_ndk_repository now creates a cc_library (@androidndk//:cpufeatures) for the cpufeatures library that is bundled in the Android NDK. See https://developer.android.com/ndk/guides/cpu-features.html for more details.
• 'output_groups' and 'instrumented_files' cannot be specified in DefaultInfo.
• You can increase the CPU reservation for tests by adding a "cpu:" (e.g. "cpu:4" for four cores) tag to their rule in a BUILD file. This can be used if tests would otherwise overwhelm your system if there's too much parallelism.
• Deprecate use_singlejar_for_proguard_libraryjars and force behavior to always on.

     Add the appropriate cxx_builtin_include_directory entries for
     clang to the Android NDK crosstool created by
     android_ndk_repository.

Incompatible changes:

• Depsets (former sets) are converted to strings as "depset(...)" instead of "set(...)".
• Using --symlink_prefix is now applied to the output symlink (e.g. bazel-out) and the exec root symlink (e.g. bazel-workspace).
• Bazel now uses the test's PATH for commands specified as --run_under; this can affect users who explicitly set PATH to a more restrictive value than the default, which is to forward the local PATH
• It's not allowed anymore to compare objects of different types (i.e. a string to an integer) and objects for which comparison rules are not defined (i.e. a dict to another dict) using order operators.

New features:

• environ parameter to the repository_rule function let defines a list of environment variables for which a change of value will trigger a repository refetching.

Important changes:

• android_ndk_repository now supports Android NDK R13.
• Android resource shrinking is now available for android_binary rules. To enable, set the attribute 'shrink_resources = 1'. See https://bazel.build/versions/master/docs/be/android.html#android_b inary.shrink_resources.
• resolve_command/action's input_manifest return/parameter is now list
• For increased compatibility with environments where UTS namespaces are not available, the Linux sandbox no longer hides the hostname of the local machine by default. Use --sandbox_fake_hostname to re-enable this feature.
• proto_library: alias libraries produce empty files for descriptor sets.
• Adds pkg_rpm rule for generating RPM packages.
• Allow CROSSTOOL files to have linker flags specific to static shared libraries.
• Make it mandatory for Java test suites in bazel codebase, to contain at least one test.
• Support for Java 8 lambdas, method references, type annotations and repeated annotations in Android builds with --experimental_desugar_for_android.
• Removed .xcodeproj automatic output from objc rules. It can still be generated by requesting it explicitly on the command line.
• Flips --explicit_jre_deps flag on by default.
• Activate the "dbg", "fastbuild", and "opt" features in the objc CROSSTOOL.
• Remove support for configuring JDKs with filegroups; use java_runtime and java_runtime_suite instead

Release 0.4.4 (2017-02-01)

Baseline: 4bf8cc30a

Cherry picks:
   + ef1c6fd33: msvc_tools.py.tpl: Change default runtime library to
              static

Incompatible changes:

• Only targets with public visibility can be bound to something in //external: .
• The deprecated -x startup option has been removed.
• docker_build: change the repository names embedded by docker_build. You can revert to the old behavior by setting legacy_repository_naming=True.
• The string methods strip(), lstrip(), and rstrip() now by default remove the same whitespace characters as Python 3 does, and accept None as an argument.
• Deprecated globals HOST_CFG and DATA_CFG are removed. Use strings "host" and "data" instead.
• repository_ctx environment is now affected by --action_env flag (value from the client environment will be replaced by value given on the command line through --action_env).
• All executable labels must also have a cfg parameter specified.
• Removed the cmd_helper.template function. The function was equivalent to: def template(items, template): return [template.format(path = i.path, short_path = i.short_path) for i in items]
• Tuples that end with a trailing comma must now be inside parens, e.g. (1,) instead of 1,
• The traversal orders for depsets have been renamed. The old names are deprecated and will be removed in the future. New names: "stable" -> "default", "compile" -> "postorder", "link" -> "topological", "naive_link" -> "preorder".

New features:

• Skylark: you can now multiply a list by an integer to get the concatenation of N copies of this list, e.g. [a,b] * 3 = [a,b,a,b,a,b]
• Allow Android aidl tool to add a jar to the program's classpath, such as if needed to support generated sources.
• Add transitive proguard_specs when android_sdk.aidl_lib is specified
• Windows: "/dev/null" is now a supported path, e.g. --bazelrc=/dev/null now works

Important changes:

• Bazel Android builds use the apksigner tool from the Android SDK build-tools. Bazel Android builds now require build-tools version 24.0.3 or later.
• Android SDK external bindings for support libraries, e.g. //external:android/appcompat_v4, are removed because the support library JARs that they referenced no longer ship with the Android SDK.
• aar_import rule is now documented.
• An IE bug was fixed in repository_ctx.download_and_extract
• Update "-I" to "-isystem" in documentation to reflect current behavior.
• android_sdk_repository build_tools_version is now optional. The highest installed build-tools will be used if none is specified.
• New flag --sandbox_add_mount_pair to specify customized source:target path pairs to bind mount inside the sandbox.
• expose proto_library descriptor set to skylark via .proto.descriptor_set
• The set constructor is deprecated in favor of depset
• Autodetect gold linker in cc_configure.bzl
• Remove build flag --experimental_j2objc_annotation_processing. It is on by default now.
• Set clang's -mwatchos-version-min correctly using the value of --watchos_minimum_os, not --watchos_sdk_version.
• singlejar can now create jar files larger than 4GB.
• android_sdk_repository and android_ndk_repository now read $ANDROID_HOME and $ANDROID_NDK_HOME if the path attribute is not set.
• Removed broken api levels 3, 4 and 5 from Android NDK 12.
• Default --android_dynamic_mode to off.
• android_sdk_repository no longer requires api_level. If one is not specified, the highest android platform installed will be used. Furthermore, android_sdk's are created for all android platforms installed and can be specified with the --android_sdk flag.
• To iterate over or test for membership in a set, prefer using the new to_list() method. E.g., "for x in myset.to_list():", or "print(x in myset.to_list())". Iteration/membership-test on the raw set itself is deprecated.
• Remove support for --javawarn; use e.g. --javacopt=-Xlint:all instead

   + b11dd48: Fix bad bug with the parallel implementation of
              BinaryOperatorExpression. Turns out that
              ForkJoinTask#adapt(Callable) returns a ForkJoinTask
              whose Future#get on error throws a ExecutionException
              wrapping a RuntimeException wrapping the thrown checked
              exception from the callable. This is documented
              behavior [1] that I incorrectly didn't know about.
   + 9012bf1: Fix scripts/packages/convert_changelog to read the
              changelog correctly

   + 05fd076: Disable sandboxing for XibCompile actions.

Incompatible changes:

• Skylark maven_jar and maven_aar settings attribute is now a label so it can be checked into your workspace.
• --{no}experimental_use_rclass_generator is now a nop.

New features:

• Coverage support (experimental) for pure Java target. Use bazel coverage //my:target to generate coverage information from a java_test.

Important changes:

• Enable fallback URLs in Skylark http rules.
• cc_proto_library generates C++ code from proto_library rules.
• cc_library now supports the strip_prefix and strip_include_prefix attributes for control of include paths.
• Skylark dicts internally don't rely on keys order anymore and accept any hashable values (i.e. structs with immutable values) as keys. Iteration order of dictionaries is no longer specified.

Release 0.4.2 (2016-12-02)

Baseline: 6331a94

Cherry picks:
   + 7b835d9: Do not patch WORKSPACE in the release process

Incompatible changes:

• Callback functions in Skylark no longer support the cfg parameter. This is a cleanup and only affects the signatures of callbacks, since the parameter hasn't been set since September 2016.

Important changes:

• Alias proto_library's produce a descriptor set that contains all srcs of its dependencies.
• proto_library supports strict proto deps.
• Top level @androidsdk support library targets have been replaced by @androidsdk//:- for Android SDK Support and Google Play Services libraries.

Release 0.4.1 (2016-11-21)

Baseline: 9a796de

Cherry picks:
   + 88bfe85: Description redacted. -- MOS_MIGRATED_REVID=139219934
   + b09ea94: Rollback of commit
              a3f5f576cd35798140ba3e81d03d919dd4ecb847.

New features:

• android_library now has a "exported_plugins" attribute just like java_library
• Use --strict_system_includes to apply hdrs_check=strict also to cc_library.includes, even if sandboxing is disabled.
• Bazel on Windows: java_binary can now be the executable of Skylark rule actions (ctx.action's executable argument)
• Packages are defined in BUILD.bazel as well as BUILD files.

Important changes:

• getattr()'s 3-arg form no longer raises an error when the retrieved field is a built-in method.
• --apk_signing_method default changed to v1. Android APKs are now signed with the new ApkSignerTool by default.
• New rule: proto_lang_toolchain(), to support LANG_proto_library rules on multiple platforms.
• Fix for Android clang++ std::stack segfault on 32bit x86. See https://code.google.com/p/android/issues/detail?id=220159
• Default android_manifest_merger is now "android" which uses the official Android manifest merger. http://tools.android.com/tech-docs/new-build-system/user-guide/man ifest-merger
• Do not propagate aspect to its own attributes when using '*'.
• Comparing sets (if set1 < set2:) is not allowed anymore in Skylark because it didn't work correctly anyway.
• When --experimental_extra_action_top_level_only, Bazel reports extra-actions for actions registered by Aspects injected by a top-level rule (approximately).
• Blacklists for proto_lang_toolchain() no longer have to be proto_library's.
• Extra actions now contain aspect-related information.
• Fix slicing bug where "abc"[:-4:-1] would give wrong answer

Release 0.4.0 (2016-10-26)

Baseline: 088bbc6

Cherry picks:
   + b01160c: Stamp Windows release.
   + 2d6736e: Add --no-tty for gpg signing
   + 9b1dfb8: Remove .sig file before gpg signing
   + 81aede1: Reimplement whole archive on Windows

Incompatible changes:

• Skylark: updating list/dicts while they are being looped over is not allowed. Use an explicit copy if needed ("for x in list(mylist):").
• Bazel now uses the --cpu flag to look up Jvms; it falls back to "default" if it can't find a Jvm matching the CPU value.
• --command_port=-1 to use AF_UNIX for client/server communications is not supported anymore.
• Sandboxed actions can access the network by default, unless their target has a "block-network" tag.

New features:

• Files now have an "extension" property in Skylark.

Important changes:

• Added a new flag --sandbox_tmpfs_path, which asks the sandbox to mount an empty, writable directory at a specified path when running actions. (Supported on Linux only for now.)
• Update protoc-3.0.0-mingw.exe to a working (statically linked) binary
• apple_static_library rule to create multi-architecture static archive files from Objc/C++/Swift dependencies on apple platforms
• JS: Add support for localization with closure managed rules.
• Create a flag --android_dynamic_mode to turn off dynamic mode during the Android split transition.
• Darwin sandboxing is default.
• Remove flag --experimental_zip_tree_artifact from j2objc Java annotation processing support.
• A few functions are added to BUILD files for consistency (hash, dir, hasattr, getattr) with .bzl files, although they are not very useful.
• --watchfs is now a command option; the startup option of the same name is deprecated. I.e., use bazel build --watchfs, not blaze --watchfs build.

Release 0.3.2 (2016-10-07)

Baseline: 023a7bd

Cherry picks:
   + bebbbe5: Fix dependency on libtool's helper script

   + c30432c: Fix cc_configure on Windows
   + 95b16a8: sandbox: Replace the error-prone lazy cleanup of
              sandbox directories by a simple synchronous cleanup.
   + e898023: Fix #1849: Sandboxing on OS X should be turned off by
              default for 0.3.2.
   + ffdc05d: Add action_config and feature for linking on Windows

Incompatible changes:

• If you maintain a rule that uses persistent workers, you'll have to specify execution_requirements={"supports-workers": 1} in the ctx.action that intends to run a tool with workers. The WorkerSpawnStrategy will alert you with a warning message if you forget to make this change and fallback to non-worker based execution.
• It is now an error to include a precompiled library (.a, .lo, .so) in a cc_library which would generate a library with the same name (e.g., libfoo.so in cc_library foo) if that library also contains other linkable sources.
• The main repository's execution root is under the main repository's workspace name, not the source directory's basename. This shouldn't have any effect on most builds, but it's possible it could break someone doing weird things with paths in actions.
• Blaze doesn't support Unix domain sockets for communication between its client and server anymore. Therefore, the --command_port command line argument doesn't accept -1 as a valid value anymore.
• Skylark: It is an error to shadow a global variable with a local variable after the global has already been accessed in the function.
• bin_dir and genfiles_dir are now properties of ctx, not configuration. That is, to access the bin or genfiles directory from a Skylark rule, use ctx.bin_dir or ctx.genfiles_dir (not ctx.configuration.{bin,genfiles}_dir). At the moment, you can access {bin,genfiles}_dir from either, but the ctx.configuration version will stop working in a future release.
• filegroup-based C++ toolchains are not supported anymore. --*_crosstool_top options must always point to a cc_toolchain_suite rule (or an alias of one).
• repository_ctx.{download,download_and_extract,execute} API now use named parameters for optional parameters and no longer uses argument type to distinguished between arguments (executable attribute name must be specified when preceding optional arguments are missing).

New features:

• print and fail are now available in BUILD files.

Important changes:

• Added @bazel_tools//tools/build_defs/repo/git.bzl as a Skylark rule for Git repositories.
• Added @bazel_tools//tools/build_defs/repo/maven_rules.bzl as a Skylark rule for Maven repositories.
• Add global hash() function for strings (only)
• Improve Android split transition handling.
• Removes exports_manifest attribute from android_binary rule.
• java_proto_library: control strict-deps through a rule-level and a package-level attribute.
• Persistent workers are now used by default for Java compilation in Bazel, which should speed up your Java builds by ~4x. You can switch back to the old behavior via --strategy=Javac=standalone. Check out http://www.bazel.io/blog/2015/12/10/java-workers.html for more details.
• objc_* rules can now depend on any target that returns an "objc" provider.
• Adds support for NDK12 to android_ndk_repository rule in Bazel.
• Test targets can disable the JUnit4 test security manager via a property.
• Disable the Android split transition if --android_cpu and fat_apk_cpu are both empty.
• New sandboxing implementation for Linux in which all actions run in a separate execroot that contains input files as symlinks back to the originals in the workspace. The running action now has read-write access to its execroot and /tmp only and can no longer write in arbitrary other places in the file system.
• Add worker support to single jar.
• Invoke source jar action as a worker.
• Sandboxed builds allow network access for builds by default. Tests will still be run without networking, unless "requires-network" is specified as a tag.
• Add path.realpath() method for Skylark repositories.
• On Mac devices, detect locally installed versions of xcode to:
  1. Use a sensible default if xcode is required but --xcode_version is unspecified.
  2. Use sensible default iOS SDK version for the targeted version of xcode if ios_sdk_version is unspecified.
• Emacs' [C-x `], a.k.a. next-error, works again in emacsen >= 25.1
• swift_library can be used to build watchOS apps.
• Exposes the is_device field on Apple platform objects and adds the apple_common.platform_type(name) method to retrieve a platform_type value that can be passed to methods like the Apple fragment's multi_arch_platform.
• Move Skylark git_repository rules to git.bzl
• Add support for aspects to attr.label() attributes
• Global varaiables HOST_CFG and DATA_CFG are deprecated in favor of strings "host" and "data. Argument cfg = "host" or cfg = "data" is mandatory if executable = True is provided for a label.
• The deprecation attribute of all rules now causes warnings to be printed when other targets depend on a target with that attribute set.
• Change default of --[no]instrument_test_targets to false, change default --instrumentation_filter (which previously tried to exclude test targets by heuristic) to only exclude targets in javatests.
• Remove deprecated absolute paths in blaze IDE artifacts
• When using android_binary.manifest_merger="android" the merger produces a summary log next to the merged manifest artifact.
• Allow different default mallocs per configuration.

Release 0.3.1 (2016-07-29)

Baseline: 792a9d6

Cherry picks:
   + 25e5995: Rollback of commit
              a2770334ea3f3111026eb3e1368586921468710c.
   + 2479405: Fix NPE with unset maven_jar sha1
   + 3cf2126: Rewrite the extra action info files if the data within
              them changes.
   + 5a9c6b4: JavaBuilder: Reintroduce the -extra_checks flag.

Incompatible changes:

• Removed predefined Python variable "generic_cpu".
• Skylark rules: if you set "outputs" or an attribute to a function, this function must now list its required attributes as parameters (instead of an attribute map).
• The host_platform and target_platform entries are not written to the master log anymore.
• Bazel requires Hazelcast 3.6 or higher now for remote execution support, because we upgraded our client library and the protocol it uses is incompatible with older versions.

New features:

• LIPO context (--lipo_context) can now also be a cc_test (in addition to cc_binary)

Important changes:

• If --android_crosstool_top is set, native code compiled for android will always use --android_compiler and not --compiler in choosing the crosstool toolchain, and will use --android_cpu if --fat_apk_cpu is not set.
• Add --instrument_test_targets option.
• apple_binary supports a new platform_type attribute, which, if set to "watchos", will build dependencies for Apple's watchOS2.
• objc_binary now supports late-loaded dynamic frameworks.
• Native Swift rules no longer pull in module maps unconditionally. Use --experimental_objc_enable_module_maps for that.
• Merged manifests are guaranteed to have the application element as the last child of the manifest element as required by Android N.
• The Android manifest merger is now available as an option for android_binary rules. The merger will honor tools annotations in AndroidManifest.xml and will perform placeholder substitutions using the values specified in android_binary.manifest_values. The merger may be selected by setting the manifest_merger attribute on android_binary.
• The progress message would not clear packages that need to be loaded twice.
• Remove warning for high value of --jobs.
• Use the correct build configuration for shared native deps during Android split transitions.
• When building ObjectiveC++, pass the flag -std=gnu++11.
• use xcrun simctl instead of iossim to launch the app for "blaze run".
• Glob arguments 'exclude' and 'exclude_directories' must be named
• Bazel no longer regards an empty file as changed if its mtime has changed.

Release 0.3.0 (2016-06-10)

Baseline: a9301fa

Cherry picks:
   + ff30a73: Turn --legacy_external_runfiles back on by default
   + aeee3b8: Fix delete[] warning on fsevents.cc

Incompatible changes:

• The --cwarn command line option is not supported anymore. Use --copt instead.

New features:

• On OSX, --watchfs now uses FsEvents to be notified of changes from the filesystem (previously, this flag had no effect on OS X).
• add support for the '-=', '*=', '/=', and'%=' operators to skylark. Notably, we do not support '|=' because the semantics of skylark sets are sufficiently different from python sets.

Important changes:

• Use singular form when appropriate in blaze's test result summary message.
• Added supported for Android NDK revision 11
• --objc_generate_debug_symbols is now deprecated.
• swift_library now generates an Objective-C header for its @objc interfaces.
• new_objc_provider can now set the USES_SWIFT flag.
• objc_framework now supports dynamic frameworks.
• Symlinks in zip files are now unzipped correctly by http_archive, download_and_extract, etc.
• swift_library is now able to import framework rules such as objc_framework.
• Adds "jre_deps" attribute to j2objc_library.
• Release apple_binary rule, for creating multi-architecture ("fat") objc/cc binaries and libraries, targeting ios platforms.
• Aspects documentation added.
• The --ues_isystem_for_includes command line option is not supported anymore.
• global function 'provider' is removed from .bzl files. Providers can only be accessed through fields in a 'target' object.

Release 0.2.3 (2016-05-10)

Baseline: 5a2dd7a

Incompatible changes:

• All repositories are now directly under the x.runfiles directory in the runfiles tree (previously, external repositories were at x.runfiles/main-repo/external/other-repo. This simplifies handling remote repository runfiles considerably, but will break existing references to external repository runfiles. Furthermore, if a Bazel project does not provide a workspace name in the WORKSPACE file, Bazel will now default to using main as the workspace name (instead of "", as previously). The repository's runfiles will appear under x.runfiles/main/.
• Bazel does not embed protocol buffer-related rules anymore.
• It is now an error for a cc rule's includes attribute to point to the workspace root.
• Bazel warns if a cc rule's includes attribute points out of third_party.
• Removed cc_* attributes: abi / abi_deps. Use select() instead.

New features:

• select({"//some:condition": None }) is now possible (this "unsets" the attribute).

Important changes:

• java_import now allows its 'jars' attribute to be empty.
• adds crunch_png attribute to android_binary
• Replace --java_langtools, --javabuilder_top, --singlejar_top, --genclass_top, and --ijar_top with java_toolchain.{javac,javabuilder,singlejar,genclass,ijar}
• External repository correctness fix: adding a new file/directory as a child of a new_local_repository is now noticed.
• iOS apps are signed with get-task-allow=1 unless building with -c opt.
• Generate debug symbols (-g) is enabled for all dbg builds of objc_ rules.
• Bazel's workspace name is now io_bazel. If you are using Bazel's source as an external repository, then you may want to update the name you're referring to it as or you'll begin seeing warnings about name mismatches in your code.
• Fixes integer overflow in J2ObjC sources to be Java-compatible.
• A FlagPolicy specified via the --invocation_policy flag will now match the current command if any of its commands matches any of the commands the current command inherits from, as opposed to just the current command.
• The key for the map to cc_toolchain_suite.toolchains is now a string of the form "cpu|compiler" (previously, it was just "cpu").
• Fix interaction between LIPO builds and C++ header modules.
• Ctrl-C will now interrupt a download, instead of waiting for it to finish.
• Proxy settings can now be specified in http_proxy and https_proxy environment variables (not just HTTP_PROXY and HTTPS_PROXY).
• Skylark targets can now read include directories from ObjcProvider.
• Expose parameterized aspects to Skylark.
• Support alwayslink cc_library dependencies in objc binaries.
• Import cc_library dependencies in generated Xcode project.

Release 0.2.1 (2016-03-21)

Baseline: 19b5675

Incompatible changes:

• Skylark rules that are available from their own repository will now issue a warning when accessed through @bazel_tools.
• Set --legacy_bazel_java_test to off by default. java_test will now have a slightly different behaviour, correctly emitting XML file but, as a downside, it needs correct declaration of the test suite (see bazelbuild#1017).
• Labels in .bzl files in remote repositories will be resolved relative to their repository (instead of the repository the Skylark rule is used in).
• Renamed proto_java_library to java_proto_library. The former is now deprecated and will print out a warning when used.
• android_sdk now compiles android_jack on the fly from android_jar, which means android_jar must be a jar and android_jack is now deprecated. The Jack tools (jack, jill, resource_extractor) must be specified.
• Any project that depended on the objc_options rule will be broken. Can be fixed by adding attrs (infoplists,copts) directly to rules depending on the options.
• .aidl files correctly require import statements for types defined in the same package and the same android_library.

New features:

• Experimental Windows support is available.
• Experimental support for writing remote repository rules in Skylark is available.
• iOS ipa_post_processor attribute allows for user-defined IPA edits.
• Adds a to_json method to Skylark structs, providing conversion to JSON format.
• Native python rule can depend on skylark rule as long as skylark rule provides 'py' provider.
• When using both --verbose_failures and --sandbox_debug, Bazel prints instructions how to spawn a debugging shell inside the sandbox.
• add flag --sandbox_add_path, which takes a list of additional paths as argument and mount these paths to sandbox.

Important changes:

• @androidsdk//:org_apache_http_legacy added for the legacy Apache classes for android sdk version 23 and above.
• Genrules correctly work when used with bazel run.
• When namespace-sandbox is run with the -D (debug) flag and inside a terminal, it spawns a shell inside the sandbox to aid in debugging when the sandboxed command fails.
• Added --artifact to workspace generator for generating workspace and build file rules from artifact coodrinates.
• Specifying --experimental_android_resource_shrinking on the command line will enable a resource shrinking pass on android_binary targets that already use Proguard.
• J2ObjC updated to 1.0.1 release.
• Added "root_symlinks" and "symlinks" parameters to Skylark runfiles() method.
• You can no longer use objc_binary targets for the xctest_app attribute of an ios_test rule.
• Enable overriding jsonnet binaries and stdlib for Jsonnet rules.
• mount target of /etc/resolv.conf if it is a symlink.
• Tests that failed to build because execution was halted no longer print their status.
• Bazel warns if a cc rule's includes attribute contains up-level references that escape its package.
• Add repository_ctx.download and repository_ctx.download_and_extract function.

Release 0.2.0 (2016-02-18)

Baseline: 9e100ac

Incompatible changes:

• ObjC compile actions for J2ObjC-translated code now only has access to headers from the java deps of the associated original java rule. These compile actions no longer takes the compiler options specified in "copts" attribute on objc_binary/ios_test rules. J2ObjC dead code removal (enabled through flag "--j2objc_dead_code_removal") now happens after ObjC compilation.
• maven_jar no longer supports separate artifact_id, group_id, and verison fields. This information should be provided in the artifact field, instead.

New features:

• Better support for toolchains that don't have a dynamic linker.
• build_file_content attribute added to new_git_repository, new_http_archive, and new_local_repository.
• Add support for .tar.bz2 archives to http_archive rules.

Important changes:

• The --skyframe flag is no longer available for the build command.
• The --artifacts flag was removed from the dump command.
• The sha256 attribute is now optional (although recommended!) for remote repository rules.
• Add instrumented file provider support to Skylark rules.
• Add imports attribute to native Python rules.
• Allow overriding -gsplit-dwarf from copts.
• Improved sandbox performance on XFS filesystems.

Release 0.1.5 (2016-02-05)

Baseline: 3a95f35
   + 8378cd8: Rollback of commit
              a9b84575a32476a5faf991da22b44661d75c19b6.

Incompatible changes:

• Set stamping to false by default (i.e., --nostamp)
• Removed --objc_dump_syms_binary.
• Removes --objc_gcov_binary flag.
• Remove JAVAC "Make" variable
• The startup flag --blaze_cpu is removed,

New features:

• A new java test runner that support XML output and test filtering is supported. It can be used by specifying --nolegacy_bazel_java_test or by specifying the test_class attribute on a java_test.
• Skylark aspects can now specify configuration fragment dependencies with fragments and host_fragments like rules can.

Important changes:

• Support for downloading remote resources through proxies by setting HTTP_PROXY (or HTTPS_PROXY).
• Timestamps within Android apks are removed to make apks deterministic.
• Support aggregation over existing rules in Skylark extensions through native.rules and native.rule.
• A tools/bazel script in the workspace will be executed as an opportunity to use a fixed version of Bazel (not implemented for the homebrew recipe yet).
• --noimplicit_deps and --nohost_deps work correctly for Aspect attributes.
• JDK-related targets are now available via @local_jdk (instead of @local-jdk).
• j2objc tools can now be accessed via @bazel_j2objc, not @bazel-j2objc.
• Repository rules must use names that are valid workspace names.
• [rust] Update to Rust 1.6
• Add support for .tar.xz archives to http_archive rules.
• Make C++ modules compatible with tools using --compilation_prerequisites_only
• [d] Update to DMD 2.070.0

Release 0.1.4 (2016-01-15)

   + 7751d43: Add a method for getting the root of a rule workspace
              to the Label method

Important changes:

• add loadfiles() query operator, to find skylark files loaded by targets.
• Added ability to declare and use aspects in Skylark.
• Skylark load statements may now reference .bzl files via build labels, in addition to paths. In particular, such labels can be used to reference Skylark files in external repositories; e.g., load("@my_external_repo//some_pkg:some_file.bzl", ...). Path-based loads are now deprecated and may be disabled in the future. Caveats: Skylark files currently do not respect package visibility; i.e., all Skylark files are effectively public. Also, loads may not reference the special //external package.
• Relative paths can now be used for 'path' with new_local_repository and local_repository.

Release 0.1.3 (2016-01-07)

Baseline: 23ad8f6

• .bazelrc allows workspace-relative imports as "import %workspace%/path/to/rcfile"
• Evaluate the query expression in a file by passing --query_file= to query

Important changes:

• Remove obsolete --objc_per_proto_includes flag.
• iOS apps and extensions now have launch_storyboard
• Passing multiple JVM options via a single --host_jvm_args flag is now deprecated. Pass each JVM option behind its own --host_jvm_args flag.
• Resources defined locally on an android_library rule will respect the neverlink attribute.
• Update Rust to 1.4
• Fix resource handling for exported android_library rules
• Files in external repositories are now treated as mutable, which will make the correctness guarantees of using external repositories stronger (existent), but may cause performance penalties.

Release 0.1.2 (2015-11-20)

Baseline: ee0ade3
   + 1e66ccd: RELNOTES: Symlink dirents of directories containing a
              file named
              "DONT_FOLLOW_SYMLINKS_WHEN_TRAVERSING_THIS_DIRECTORY_VIA
              _A_RECURSIVE_TARGET_PATTERN" will *not* be traversed
              for transitive target patterns. The motivation here is
              to allow directories that intentionally contain wonky
              symlinks (e.g. foo/bar -> foo) to opt out of being
              consumed by Blaze. For example, given
   + f5773fc: Set the ijar MAX_BUFFER_SIZE to 256 MB

New features:

• java_library now supports the proguard_specs attribute for passing Proguard configuration up to Android (not Java) binaries.
• http_file can specify "executable" to make the downloaded file runnable.
• Debian and tar packaging is now supported (see tools/build_defs/pkg/README.md).
• cpxx_builtin_include_directory specifications allow more flexibility.
• accept %crosstool_top% in cxx_builtin_include_directory
• android_binary now supports proguard_apply_mapping to re-use a previously generated proguard mapping.

Important changes:

• remove webstatusserver (--use_webstatusserver).
• Add support for objc textual headers, which will not be compiled when modules are enabled.
• actoolzip, momczip and swiftstdlibtoolzip have all been made into bash scripts and have been renamed to actoolwrapper, momcwrapper and swiftstdlibtoolwrapper respectively. The old versions will be deleted in a later change.
• [rust] Add rust_bench_test and rust_doc_test rules and improve usability of rust_test tule.
• Java rules now support a resource_strip_prefix attribute that allows the removal of path prefixes from Java resources.
• [docker_build] incremental loading is default now. Specify explicitly //package:target.tar (with the .tar extension) to obtain the full image.
• --ios_signing_cert_name allows specifying a cert for iOS app signing
• Go rules for Bazel.
• [jsonnet] Update to Jsonnet 0.8.1.
• [jsonnet] Add vars and code_vars attributes to jsonnet_to_json to allow passing external variables to Jsonnet via --var and --code_var.
• Adds --override_workspace_root blaze flag to hand-set workspace_root and mainGroup in xcodeproj.
• Allow dots in package names.
• When used as a forwarding rule (i.e., has no sources), android_library will also forward any exported_plugins in its dependencies.
• Add support for Windows-created zip files with non-posix permissions.
• [jsonnet] Add jsonnet_to_json_test rule for testing Jsonnet code.
• C++ compile actions run in a sandbox now on systems that support sandboxed execution.
• The names of the clang compilers in the Android NDK crosstool no longer reference gcc.
• 420 dpi is now a valid density for andoid_binary.densities.
• Bazel does strict validation of include files now to ensure correct incremental builds. If you see compilation errors when building C++ code, please make sure that you explicitly declare all header files in the srcs or hdrs attribute of your cc_* targets and that your cc_* targets have correct "deps" on cc_library's that they use.
• [jsonnet] Fix jsonnet_to_json rule to read code_vars from code_vars instead of vars.
• Tests, genrules, and Skylark actions without the "requires-network" tag will no longer be able to access the network.
• C++ libraries no longer need includes = ["."] (or similar copts) to include paths relative to a remote repository's root.
• Support exports attribute for android_library
• Symlink dirents of directories containing a file named "DONT_FOLLOW_SYMLINKS_WHEN_TRAVERSING_THIS_DIRECTORY_VIA_A_RECURSI VE_TARGET_PATTERN" will not be traversed for transitive target patterns. The motivation here is to allow directories that intentionally contain wonky symlinks (e.g. foo/bar -> foo) to opt out of being consumed by Blaze.

Release 0.1.1 (2015-10-05)

Baseline: 22616ae
   + 1ef338f: Rollback of "Propagates cc_library linkopts attribute
              to dependent objc_libraries.": breaks certain
              objc_binary build targets.
   + 5fb1073: Reintroduce an inconsistency check (albeit, in a weaker
              form) removed by a previous change that was trying to
              optimize away a filesystem call.
   + 6d00468b2eb976866cfb814d562e0d53a580a46f: Add IdlClass to the embedded default android tools
              repository and rearrange BuildJar's JarHelper so that
              it too can be embedded.
   + a5199039934a2e399a7201adc0d74e2f2d2b0ff3: Fixes Android integration tests by wiring up idlclass
              rules in integration environment.

Incompatible changes:

• Bazel requires JDK 8 to run.
• Attribute "copts" is removed from j2objc_library.

New features:

• a cc_binary rule may list '.s' and '.asm' files in the srcs
• Support for build with libsass.
• labels in "linkopts" may match any label in either "deps" or "srcs" to be considered valid.
• Maven servers that require username & password authentication are now supported (see maven_server documentation).

Important changes:

• Support empty plist files
• The section of the AndroidManifest.xml will not be overwritten if it already contains a tag for each of the densities specified on the android_binary rule.
• Add Jsonnet rules to Bazel
• Remove deprecated xcode_options flag.
• Workspace names are now restricted to being in their base directory (that is, the names cannot contain up-level references or /./).
• j2objc_library on Bazel now transpiles transitive proto_library dependencies. (Note that java_* rules in Bazel do not yet support protos; currently they ignore proto dependencies.)
• new_http_archive can specify a root directory.
• Adds support for dylibs on devices for Xcode 7.
• [d] d_docs rules now depend on a d_binary, a d_library or d_source_library.
• [docker] docker_build now set the permission to 0555 to files added to the layer, use mode = "0644" to use the legacy behavior.
• android_binary now has a main_dex_proguard_specs attribute to specify which classes should be in the main dex.
• [rust] Add rust_docs rule for generating rustdoc.

Release 0.1.0 (2015-09-08)

   + 2984f1c: Adds some safety checks in the Bazel installer
   + 4e21d90: Remove BUILD.glob and incorporate the necessary
              filegroups into the android_{ndk,sdk}_repository rules
              themselves.
   + 1ee813e: Fix Groovy rules to work with sandboxing
   + 8741978: Add initial D rules to Bazel.
