OSv Release 0.18

We are pleased to announce the release of OSv 0.18 Release. Please note this is not the Beta release, which is only available via registration

Release 0.18 is focused on bug fixes. Two noteworthy additions:

1. Added support for applications using the AVX instruction set for 256-bit SIMD (vectorized) operations. One example of such application is DPDK.
2. Support shared libraries which use initial-exec TLS (e.g., compiled with -ftls-model=initial-exec).
