Why is my PR not on the queue?

This page was last updated on: June 19, 2026 at 19:11 UTC

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

be based on the master branch of mathlib,
pass mathlib's CI,
not be blocked by another PR (as marked by the labels blocked-by-other-PR and similar)
have no merge conflict (as marked by the merge-conflict),
not be in draft status, nor labelled with one of WIP, help-wanted or please-adopt: these mean the PR is not fully ready yet;
not be labelled awaiting-CI, awaiting-author or awaiting-zulip,
not be labelled delegated, auto-merge-after-CI or ready-to-merge: these labels mean your PR is already approved.

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.
