- Profile redesign polish - account header banners refactored, better link colors in bio, display name overflow handling, improved number fields layout and spacing
- Big accessibility pass - list semantics and landmark regions across the main navigation, footer, settings and login/sign-up pages, visible focus outlines on search and composer fields, and selected-state cues on the follows/followers filters
- Admin: manage email subscriptions from the admin UI, search email blocks by domain
- API: retrieve both resolved and unresolved reports, allow the HTML lang attribute on remote posts
- Search results page keeps the search field and tabs sticky
🔧 Fixes & improvements
- Custom emoji selection and the emoji picker rendering when there are no custom emojis
- Several collection bugs - crashes rendering remote posts with a collection card, notification URLs, item position updates, "New collection" link showing on other people's profiles
- Profile fields not showing links, bio line spacing with and without paragraph tags, account header banner grayscale
- Remote posts with large media descriptions no longer rejected
- Text overflow in the list item component
- Unblocking a domain now updates the blocked-domains list

🐦⬛ Ours: Mastodon Bird UI 4.0.0-alpha.8.rc2 (nightly)
- Adapt profile styles to the new account_header module classes after upstream renamed (#38863) and removed (#38920) the old profile classes - avatar size and position, role badges, "Follows you" badge, tabs and buttons all restored
- Restore the navigation menu order after upstream wrapped the items in list elements (#39145): Lists and Followed tags at the bottom, More as the last item
- Hide the navigation separators that replaced the old hr elements
- Restore even profile tab distribution at all widths
- Fix familiar followers spacing when no role badges are present
- Video previews behind a content warning use object-fit cover so portrait videos no longer letterbox
🔧 Ours: Mementomori.social Mastodon fork fixes
