We've successfully upgraded our Mastodon server to v4.6.0-alpha.8+mementomods-2026-05-24, along with Mastodon Bird UI 4.0.0-alpha.8.rc2.

This update includes today's latest daily build with 158 new commits from upstream since mementomods-2026-05-02.

What's new in Mastodon core - These are the changes Mastodon Team have introduced us in the latest nightly version we are running:

✨️ New features

- Collections keep maturing - add an account to a collection straight from its profile, choose how accounts are sorted in a collection, language added to the collection payload, partial accounts in the collections endpoint, plus batch actions and reporting for collections in the moderation tools
- 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
- Role management can require 2FA for all users
- nan-tw added to supported locales

📦 Dependency updates

- Vite 8.0.13, TypeScript 6.0.3, Sidekiq 8.1.5, Devise 5.0.4 (security), axios 1.16.1, FFmpeg 8.1.1, aws-sdk bumps, and dozens of smaller updates

🐦‍⬛ 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

- Merged the latest upstream into our fork and resolved the conflicts, keeping all our customizations
- Re-synced the vendored Mastodon Bird UI to 4.0.0-alpha.8.rc2

figured this out: neuromatch.social/@jonny/11658…

we have struggled for awhile with how to make instancewide information salient - announcements aren't exactly that, and many ppl don't know they exist. in particular we wanted to do voting within the instance, but we would have to go and boost the poll a bunch of times and only a few people ended up seeing it.

so this lil change might be of general interest to small instances out there - added the ability for moderators to sticky/unsticky posts and have them stay at the top of local and home feeds. we'll trial it out and see how it goes.

what up if any #mastodev or rails or redux knowers are around here, we are trying to do somethign super simple that might be generally useful for small instances: we want to potentially move instancewide votes onto the instance rather than a separate loomio instance, but to make that possible we have to make sticky posts where a vote can be pinned to the top of everyone's feeds.

this should be super simple but for the life of me i can't make heads or tails of this damned redux thing. if anyone is kind enough to take a look or help me finish this, i will pay you back by trying to pull this up to glitch so everyone can have it

We just upgraded our Mastodon fork on Mementomori.social to support Mastodon Bird UI with Mastodon 4.6.0 theme variations.

Mastodon Bird UI is now at 4.0.0-alpha.8.rc with support for Color scheme and Contrast settings.

New settings in Settings → Preferences → Appearance:

- Use stars instead of hearts for favourites
- Hide Translate links on Finnish posts
- Hide all Translate links

These used to be separate themes; now you can mix and match.

The Theme dropdown is shorter for the same reason: Light, Dark and Contrast moved into Mastodon's own radios just below the dropdown. If your previous theme is gone, pick Mastodon Bird UI and set Color scheme + tick the new checkboxes to match what you had.

Fixes in Mastodon Bird UI:

- Star icon alignment when Reduce motion is enabled
- Sparkle and ring animations now fire in both motion modes
- Notification colors that disappeared when your OS was light but Mastodon was set to dark

If anything feels off, let me or the admins know.
