gitea 1.12.4 is released, with bug fixes.
I'm running on Docker with the :latest tag, which is a development version. If you like me wanted to downgrade from 1.13-dev to 1.12.4, you'd run into Panic: unrecognized repo unit type: 8, issue 10849. The database has an enum for repo type, and 1.13 will add Kanban boards, so it's not database compatible with the previous 1.12 release.
Still trying to get my Gitea backups fully automated. I should be able to mount a temp directory onto the host with Docker Compose, and then drop a Gitea database dump there before running my nightly Restic backups. I've been doing this by hand every night, so it gets a little easier each time, but still there are a few fiddly bits that I don't have sorted out.
Incremental progress gives me something to write about every night.
