Updating Releases.md failed, but other than that looks good:

Error: Error executing git: fatal: No tags can describe 'd5cd7c3261427fac3cf2b1aef8f38640596e9859'.
Try --always, or create some tags.

Updating Releases.md failed. Please manually run `git log --oneline VERSION_FROM..VERSION_TO` and use the output to update Releases.md

Edit: Cool. I can reproduce this if I follow what the CI does in a fresh directory.
Edit 2: Opened #14166 for next time.
