We have resolved a regression present when using merge queue with either squash merges or rebases. If you use merge queue in this configuration, some pull requests may have been merged incorrectly between 2026-04-23 16:05-20:43 UTC.
This behavior is still present in GitHub Enterprise Cloud with Data Residency, and we are rolling out the same fix.
