New Mastodon release 4.5.12 (security) is now installed on all customer instances. https://github.com/mastodon/mastodon/releases/tag/v4.5.12 Progress update on the 4.6 upgrade: The new version needs a newer ffmpeg, and since we'd rather not compile that ourselves, we're upgrading Debian from 11 to 13 across all instances (we need to do this eventually anyway). Instances mostly stay online during this — aside from the occasional service restart and the required reboots. 40% are already done. After the upgrade, two things follow: 1. The database needs reindexing, thanks to the dreaded "collation version mismatch". 2. We're dropping the unmaintained Elasticsearch 7 and moving every instance with search enabled to Elasticsearch 9. Both steps can take a considerable amount of time — days for larger instances — but with enough free disk space they can run while your instance stays online. We rebuild the search index from scratch, so search may be incomplete or feel a bit off over the next few days. When that is done for all instances, we will upgrade Mastodon to version 4.6.
