Expected release date: September 2018

Beta 1 should be out later this month.


Expected changes to Bazel:

  • Remove support for non-libc++ STLs

libc++ has been the default for a release and has proven to be stable. It is a strict improvement over the other STLs (more features, better Clang compatibility, Apache licensed, most reliable). The fact that the NDK supports multiple STLs is a common pain point for users (it's confusing for newcomers, and it makes sharing libraries difficult because they must all use the same STL).

Now that we have a good choice for a single STL, we‘ll remove the others. We’ll most likely move the source we have for these along with building instructions to a separate project so that people that need these for ABI compatibility reasons can continue using them, but support for these will end completely.

  • Remove support for GCC

GCC is still in the NDK today because some of gnustl's C++11 features were written such that they do not work with Clang (threading and atomics, mostly). Now that libc++ is the best choice of STL, this is no longer blocking, so GCC can be removed.

Looking at this, support should be pretty simple it seems? Even almost working as-is?
