Release Notes

Released on 2026-04-13.

Highlight

prek auto-update is now stricter about pinned revisions and more useful in CI.
It now keeps rev and # frozen: comments in sync, can detect
impostor commits when validating pinned SHAs,
and lets you use prek auto-update --check to fail on both available updates and frozen-ref
mismatches without rewriting the config.

Examples:

$ prek auto-update
# updates revs and repairs stale `# frozen:` comments

$ prek auto-update --freeze
# writes frozen SHAs with matching `# frozen: <tag>` comments

$ prek auto-update --check
# exits non-zero when updates are available, a `# frozen:` comment is stale,
# or a pinned SHA does not belong to the fetched upstream refs
