[AOMP Release 23.0-0](https://github.com/ROCm/aomp/releases/tag/rel_23.0-0)
These are the release notes for AOMP 23.0-0. AOMP uses AMD developer modifications to the upstream LLVM development trunk. These differences are managed in a branch called "amd-staging". This branch is found in a mirror of upstream LLVM found at https://github.com/ROCm/llvm-project. The amd-staging branch is constantly changing as it merges the upstream development trunk with its downstream development updates. The AMD modifications are experimental while under review for the upstream trunk. AOMP uses a snapshot of amd-staging at the commit ids and dates listed below. AOMP also includes builds of related ROCm components. We call AOMP a "standalone" build as it does not use or require ROCm with the exception of the kernel module (amdgpu-dkms) and libdrm which are often part of the Linux distribution. AOMP is isolated from any ROCm installations by installing into /usr/lib/aomp and the use of RPATH for runtime libraries.

For AOMP 23.0-0, the last LLVM trunk commit is a 82447b92c37842b33e708146ba4ec794bb9fae98 on February 12, 2026. The last amd-only commit is ae56654bd26b8475fc000b1a2a8a80557fe7c83f on February 12, 2026. These commits form a frozen branch now called "aomp-23.0-0". See https://github.com/ROCm/llvm-project/tree/aomp-23.0-0.
