Hi!
Version 17.0.0-rc3 of LLVM and all it’s subprojects (clang, lld, mlir, libc++ and more) is now released!
Find the binaries and sources on the GitHub release page.
The diff for RC2->RC3 is massive, and I wrote some notes about the plan for final in the release testers forum, the TLDR of that is that if we continue to get this huge amount of fixes in the next two weeks it is safer to do an RC4 release instead of going directly to -final.
