Mastodon now supports automatic switching between the light and dark theme, depending on your system setting.

It will be available in the upcoming 4.3 version, or is already there if your instance runs the nightly code.

You can switch to this new automatic theme in your Appearance preferences. Instance admins can also set it as the default theme (I just did it on mastodon.social and mastodon.online).

This has been done in https://github.com/mastodon/mastodon/pull/29748, thanks a lot to @nshki for the initial PR!

Support "system" theme setting (light/dark theme depending on user system preference) by renchap · Pull Request #29748 · mastodon/mastodon

Another recently merged feature is the new "severed relationship" notifications. Those will appear when a moderator or admin blocks a user or a whole domain and this action caused you to loose some follows or followers.

Those blocks used to be invisible to users, you maybe saw your follows/followers count decrease but nothing more. Now you can access a list of those blocks, and download a CSV file with the list of impacted accounts.

@renchap On one hand this seems like a good change because transparency is important and can help users make informed decisions.

Although on the other hand with how the #threads situation and admins going under #NDA I can also see this being used as a divisive tactic to turn users against servers and admins.

So this feature really is a double edged sword and could be a transparency tool but also could have ulterior motives in its implementation.

So while I think it is good to show lost follows from #defederation, I'm not so keen on notifications when admins sever follows, as that seems divisive.
