Why is my PR not on the queue?

This page was last updated on: July 05, 2025 at 10:20 UTC

To appear on the review queue, your open pull request must...

For PRs which add new code (as opposed to e.g. performance optimisation, refactoring or documentation), it is very helpful to add a corresponding area label. Otherwise, it may take longer to find a suitable reviewer.

The table below contains all open PRs against the master branch which are not in draft mode. For each PR, it shows whether the checks above are satisfied. You can filter that list by entering terms into the search box, such as the PR number or your github username.
