+### Added
+
+- Add warning on direct messages screen in web UI ([Gargron](https://github.com/mastodon/mastodon/pull/18289))
+  - We already had a warning when composing a direct message, it has now been reworded to be more clear
+  - Same warning is now displayed when viewing sent and received direct messages
+- Add ability to set approval-based registration through tootctl ([ClearlyClaire](https://github.com/mastodon/mastodon/pull/18248))
+- Add pre-filling of domain from search filter in domain allow/block admin UI ([ClearlyClaire](https://github.com/mastodon/mastodon/pull/18172))
+
+## Changed
+
+- Change name of “Direct” visibility to “Mentioned people only” in web UI ([Gargron](https://github.com/mastodon/mastodon/pull/18146), [Gargron](https://github.com/mastodon/mastodon/pull/18289), [ClearlyClaire](https://github.com/mastodon/mastodon/pull/18291))
+- Change trending posts to only show one post from each account ([Gargron](https://github.com/mastodon/mastodon/pull/18181))

+  - Different threads no longer have to wait on a mutex over a single connection
+  - However, this does increase the number of Redis connections by a fair amount
+  - We are planning to optimize Redis use so that the pool can be made smaller in the future
+
+## Removed
+
+- Remove IP matching from e-mail domain blocks ([Gargron](https://github.com/mastodon/mastodon/pull/18190))
+  - The IPs of the blocked e-mail domain or its MX records are no longer checked
+  - Previously it was too easy to block e-mail providers by mistake
