Pre-release

Breaking changes:

  • This is the first release based on WASI snapshot 1.
  • The linux build wasi-sdk-9.0-ubuntu18.04.tar.gz requires Ubuntu 18.04. wasi-sysroot and the clang builtins can still be installed on any system already shipping with LLVM >= 8.
  • Due to regressions this release has been redacted, we will release wasi-sdk-10 shortly to take its place

Note: Path names within the wask-sdk tar archive no longer contain opt/wasi. This means that paths to WASI tools will all be shorter, but build scripts will need to be updated accordingly.

In this release, wasi-libc includes optimizations to avoid linking in command-line argument initialization code in programs that don't use command-line arguments (eg. `int main(void)), and similar to avoid linking in environment-variable initalization code in programs that don't access environment variables.

And, the wasi-sdk installation now includes common tools such as nm, ar, strings, and others.
