@Mastodon as a note the https://github.com/mastodon/mastodon/releases page says the Ruby versions is "2.5 up to 3.1" in the dependencies list, but the actual git checkout (.ruby-version) and install instructions below specify Ruby 3.0.3 instead. I assume the first is a typo, but who knows it could be the second :)
@morix I guess, 3.1 is the highest supported version and 3.0.3 is the recommended version. Many admins might prefer an older, more tested and proven to be stable release.
The Dockerfile specifies Ruby 3.0.3, too.

@morix @Mastodon you can run Mastodon with any version of ruby from 2.5 to 3.1 if you're using distro-provided Ruby for instance. Using rbenv (which is not mandatory), it'll try to use 3.0.3 by default
