👋 Hi! Thank you for contributing to the vLLM project.
Just a reminder: PRs would not trigger full CI run by default. Instead, it would only run fastcheck CI which starts running only a small and essential subset of CI tests to quickly catch errors. You can run other CI tests on top of those by going to your fastcheck build on Buildkite UI (linked in the PR checks section) and unblock them. If you do not have permission to unblock, ping simon-mo or khluu to add you in our Buildkite org.

Once the PR is approved and ready to go, your PR reviewer(s) can run CI to test the changes comprehensively before merging.

To run CI, PR reviewers can do one of these:

• Add ready label to the PR
• Enable auto-merge.

The change lgtm.

It would be nice to have a place to capture release notes for changes in behavior, deprecation notices, etc. That's not something to solve in this PR, though ...

some options:

1. A CHANGELOG.md file in the tree where PRs can add notes as part of the PR.
2. A commit message (PR description) convention that can be parsed out of the git commit log. Something like "VLLM-Release-Note: ". Then a script can extract it from the commits since the last release.

Since we don't have anything like #2 going already, I think #1 is probably more reasonable. The biggest downside to #1 is that it creates a place that will cause PRs to go into conflict when they're all trying to add a note to the same spot in the same file. It depends on how often the notes get added, and the conflicts are easy to fix, at least.

I can propose a file to start this in a follow-up PR to this one, using this PR as an example of one that could have included a note. Just let me know if you like the idea.
