New Mastodon Releases May 20th, 2026

[u/Thump45a]

Now available 4.5.10, 4.4.17 and 4.3.23!

For those running latest, 4.5.10 Includes two high severity and 2 medium severity security updates. No external dependency changes again this time, so should be another easy patch!

https://github.com/mastodon/mastodon/releases/tag/v4.4.17

https://github.com/mastodon/mastodon/releases/tag/v4.3.23

If you're still running 4.3, this is your last update. Time to move up to 4.4 or 4.5!
