If you are running Mastodon 4.1, note that it only supports Ruby 3.0 (which is no longer supported upstream) and is subject to the above SAML security issue.

If you are running Mastodon 4.2: Mastodon 4.2.17 drops support for Ruby 3.0 (which is no longer supported upstream).
If you are using Ruby 3.0, you can update to Mastodon 4.2.16 which contains the latest security fixes, but please note that this version has a known vulnerability if you are using SAML authentication with Mastodon.
If you are running Mastodon 4.2 + Ruby 3.0, we strongly encourage you to update to Ruby 3.2 and Mastodon 4.2.17 or above.

We are looking for feedback on our new grouped notifications API from Mastodon client developers.
All the details about this API are available at https://github.com/mastodon/mastodon/discussions/31618
We intend to mark this API as stable in our next 4.3 beta release, so if you are a client developer now is the time to have a look at it and tell us what you think!
