@mfelsche can you add release note items for #2997 to this issue?

[SeanTAllen]

@jemc can you add release notes for LLVM 7.0 support to this issue?

[jemc]

This release adds experimental support for LLVM 7.0; the highest officially supported LLVM version is still LLVM 3.9, with higher LLVM versions having some code-generation optimizations disabled for stability. Work to stabilize these higher version is still ongoing.

[SeanTAllen]

@jemc do you want to change the LLVM release notes at all?

[SeanTAllen]

I've opened a branch release-0.27.0 to start including release notes.

The release brings in a refactoring of the process package, and upon that a basic implementation on Windows of child Process creation and monitoring, as well as non-blocking anonymous pipes for stdin, stdout and stderr. The async pipe reading and writing are handled using a Pony timer plus polling, with IOCP support a possible future task.

[jemc]

This release adds official support for LLVM 7, LLVM 6, and LLVM 5. Previously, LLVM 3.9 was the highest officially supported version, while support for LLVM 5 and LLVM 6 was listed as experimental, and did not have all optimizations enabled. Now all the above versions are officially supported with all optimizations enabled.

[jemc]

@SeanTAllen - sorry, I don't see the branch you mentioned, so I just added updated notes here.

[SeanTAllen]

Will start release tonight (my time, eastern US)
