+  This includes a revamp of the composer interface.\
+  See https://blog.joinmastodon.org/2025/09/introducing-quote-posts/ for a user-centric overview of the feature, and https://docs.joinmastodon.org/client/quotes/ for API documentation.
+- **Add support for fetching and refreshing replies to the web UI** (#35210, #35496, #35575, #35500, #35577, #35602, #35603, #35654, #36141, #36237, #36172, #36256, #36271, #36334, #36382, #36239, #36484, #36481, #36583, #36627 and #36547 by @ClearlyClaire, @diondiondion, @Gargron and @renchap)
+- **Add ability to block words in usernames** (#35407, #35655, and #35806 by @ClearlyClaire and @Gargron)

+  This splits the `timeline_preview` setting into four more granular settings controlling live feeds and topic (hashtag, trending link) feeds.\
+  The setting for local topic feeds has 2 values: `public` and `authenticated`. Every other setting has 3 values: `public`, `authenticated`, `disabled`.\
+  When `disabled`, users with the “View live and topic feeds” will still be able to view them.

   You can now separately filter or drop notifications from people you don't follow, people who don't follow you, accounts created within the past 30 days, as well as unsolicited private mentions, and accounts limited by the moderation.\
   Instead of being outright dropped, notifications that you chose to filter are put in a separate “Filtered notifications” box that you can review separately without it clogging your main notifications.\
   This adds the following REST API endpoints:
-
   - `GET /api/v2/notifications/policy`: https://docs.joinmastodon.org/methods/notifications/#get-policy
