LLVM 19.1-rc1 was released today as the first tagged development snapshot of [1]LLVM 19 that is working its way toward the stable LLVM 19.1 version expected in September.

Earlier this week when the LLVM 19 code was branched I wrote an article outlining [2]all of the new features in LLVM 19 and Clang 19 . See that article for more details but there's a lot in new C and C++ language features, Intel Branch Hint support, new Arm cores added, Apple M4 support, initial C2Y plumbing, removing AMD 3DNow! instructions, and many other additions over the past half-year.

Those wanting to try out the LLVM 19.1-rc1 compiler stack can find the sources and binaries via the [3]LLVM Discourse .

LLVM 19.1-rc2 is expected for release around 6 August, LLVM 19.1-rc3 around 20 August, and then ideally releasing LLVM 19.1.0 around 3 September. After that will be the usual bi-weekly point release regiment.
