For the past few years, we have been creating Clang branches based on the llvm.org release branches. However, we use names like stable/<date> for these branches, which can be confusing and hard to remember the upstream branch name. To address this issue, we are going to update the branch scheme starting with release/21.x.
For example:
- llvm/llvm-project -> release/21.x
- swiftlang/llvm-project -> stable/21.x
