LLVM Clang 19 Branched, LLVM 20 Enters Development- No AMD Zen 5 "Znver5" Merged Yet
Jul. 23, 2024

As scheduled, LLVM Clang 19 was branched from mainline Git this morning and is now considered feature frozen ahead of its planned September release. LLVM Clang 20 in turn is now in development with the main Git branch.

LLVM Clang 19 (to be released as LLVM/Clang 19.1 in September as the stable release per their current versioning scheme) is the newest six-month feature update to this open-source compiler. The LLVM Clang 19.1-rc1 release candidate is expected in the coming days and at least two release candidates expected in August. If all goes according to plan, LLVM/Clang 19.1 stable will be out around 3 September.
