v1.2.0 [Colonel]

Colonel is the next major release of Coconut, and makes major feature additions and minor breaking changes over v1.1.1 [Brontosaurus]. See the updated documentation for more information on everything below.

Breaking changes:

• removed @recursive (now does auto tco)
• function composition (..) precedence changed
• removed --autopep8 flag

New features:

• automatic tail call optimization
• statement (multiline) lambdas
• command-line syntax highlighting
• --jobs flag
• assignment function notation
• @recursive_iterator
• star pattern matching
• implicit pass for data and class
• inline nonlocal and global statements
• --keeplines flag

v1.1.1 [Brontosaurus]

v1.1.1 [Brontosaurus] makes only minor feature additions over v1.1.0 [Brontosaurus], and should be fully backwards-compatible. The major changes were:

• Adding a --watch flag (#99, #106, thanks @Boscillator!)
• Improving Jupyter / IPython console autocompletion (#114)
• Adding methodcaller implicit partial (#112)
• Adding links to 3rd party Vim and Emacs highlighters (thanks, @manicmaniac and @NickSeagull!)
• Adding pip install coconut[...] as a way to install optional dependencies

v1.1.0 [Brontosaurus]

Brontosaurus makes notable feature additions over v1.0.0 [Albatross], but should be fully backwards-compatible. The major changes were:

• Adding addpattern and prepattern built-ins (#92, #103)
• Changing recommended file extension from .coc to .coco (#88)
• Making interpreter print the result of an expression (#100, thanks @Boscillator!)
• Fixing IPython / Jupyter kernel support (#97)
• Adding support for guards in pattern-matching function definition (#98)
• Upgrading to pyparsing 2.1.5

v1.0.0 [Albatross]

Albatross is the first production release (v1.0.0) of the Coconut programming language. No new features have been added since Pinnate (v0.4.1), although there have been major stability improvements. For documentation, see our new website at http://coconut-lang.org.

[P]innate

Pinnate (v0.4.1) is the first candidate release for v1.0.0. The language has become relatively stable and is unlikely to change much until a release is selected for v1.0.0.

Massive changes have been made to Coconut since Odisha (v0.3.6). If you've been following Coconut development, you should read the new tutorial and go over the new documentation to familiarize yourself with all the changes.

Pinnate is the type of leaf on the Coconut palm.

[O]disha

Major Changes:

• New: --package or -p and --standalone or -a flags for forcing the type of compilation to perform
• --print or -p is now --display or -d (-d is no longer an alias of --debug)
• Fixes issues in data mutability and augmented assignment
• Significantly increases compilation speed

Odisha is a part of India famous for its coconuts.

[N]ucifera

Major Changes:

• New: Built-in consume function for efficiently exhausting iterators
• New: Only recompiles changed files (will recompile all files if --force is passed)
• Improves (-) to support subtraction and negation
• Improves Python-version-cross-compatibility for str, bytes, and open
• Warns on mixing of tabs and spaces even if --strict isn't passed
• Changes coconut.convenience.setup function

Cocos Nucifera is the scientific name for the coconut tree.
