We've successfully upgraded our Mastodon server to v4.7.0-alpha.1+mementomods-2026-07-05. This round stays on the v4.7.0-alpha.1 nightly line we moved onto last time, so it's a within-cycle daily build rather than a version jump, just brought fully up to date with upstream.

This update includes today's latest daily build with 120 new commits from upstream since our 19.6.2026 build (mementomods-2026-06-19).

What's new in Mastodon core, these are the changes the Mastodon Team have introduced in the latest nightly version we are running:

✨️ New features

- Admins: There's now an "Update available" item at the top of the navigation when a newer Mastodon version is out, so admins notice new releases without checking manually (github.com/mastodon/mastodon/p…).
- Hashtag suggestions now work with non-Latin scripts, so autocomplete finally helps when you write tags in other writing systems (github.com/mastodon/mastodon/p…).
- Post images now render inside notification emails instead of being left out (github.com/mastodon/mastodon/p…).
- The interface keeps shifting its wording from "status" to "post" for consistency (github.com/mastodon/mastodon/p…).

🔧 Fixes & improvements

- The indentation of the reply indicator on posts was corrected (github.com/mastodon/mastodon/p…) (Mastodon Bird UI nightly also updated)
- Filters no longer occasionally apply the wrong filter because of a caching bug (github.com/mastodon/mastodon/p…).
- Fixed a visual glitch with the content warning (spoiler) button (github.com/mastodon/mastodon/p…) (Mastodon Bird UI users not affected)
- Removed a duplicate "clear" button that showed up in the search box on Chrome (github.com/mastodon/mastodon/p…) (default theme only)
- The follow button no longer floats out of place on profiles when the overview landing page is enabled (github.com/mastodon/mastodon/p…).
- Usernames no longer turn invisible during the post highlight animation (github.com/mastodon/mastodon/p…).
- The "view collection" menu item no longer appears on the collection page itself (github.com/mastodon/mastodon/p…).

🔒 Federation & security (under the hood)

- Added verification of FEP-8b32 Object Integrity Proofs and support for expiring Linked Data Signatures, part of the ongoing work to harden how servers verify each other's content (github.com/mastodon/mastodon/p…).
- Local account signing keys were moved to a dedicated keypairs table, groundwork for cleaner and safer federation cryptography.
- Added audit logs for hashtag actions so moderators have a clearer trail (github.com/mastodon/mastodon/p…).

📦 Dependency updates

- Mostly routine bumps this round (formatjs, haml_lint, CI actions and translation updates).

🐦‍⬛ Mastodon Bird UI (nightly)

4.0.0 nightly branch introduces two fixes vendored in this round:

- Fixed the reply "replied to" indicator sticking to the left edge on non-thread replies, after Mastodon narrowed its thread indent to in-thread replies only (github.com/mastodon/mastodon/p…).
- Made the left navigation menu scroll so items below Bookmarks (Settings, More) stay reachable at high browser zoom, which especially helps the accessible themes.

A tip for users of our experimental instance mementomori.social:

You can enable the algorithmic "For you" feed from the top right corner of the Home feed. When you turn it on, it will instantly switch to a ranked feed that prioritizes posts based on who you follow, who you comment on, and what you like or boost. If you also toggle on "Include posts from people you don't follow," you'll see trending content across the Fediverse based on your interests.

Unlike Trending tab, For you -feed is personal. The logic is similar to pre-Musk Twitter but user-focused and not corporate-owned.

The Trending tab remains unchanged, and /explore shows posts from roughly the past 6-12 hours, with a strong focus on the most recent ones. A post that gets massive engagement might stick around a bit longer, but most cycle out within half a day. Your own For you page changes every time you click the menu, refresh the page, or return.

This is ongoing, experimental work. The PR draft and source code are available here: github.com/mementomori-social/…

Now that I've dug my hands deep into the Mastodon core, it looks like it's definitely possible to get the original home instance counts for federated posts, not just your own server's local tally.

For boosts and favourites, recent versions of Mastodon already fetch the origin's reported totals when retrieving a post and store them as "untrusted counts" (untrusted because the remote server self-reports them). So a remote post carries the home server's actual numbers.

Replies are trickier, as they only federate to subscribed servers, so the local count tends to lag. However, you can fetch the full reply tree from the origin on demand.

I'm basing our algorithmic home feed exactly on that: boosts and favourites from the origin counts, and comments from a backfilled reply tree.

The numbers in question have been requested for ages:

We've successfully upgraded our Mastodon server to v4.7.0-alpha.1+mementomods-2026-06-19, along with Mastodon Bird UI 4.0.0. Two big milestones this round: Mastodon 4.6.0 officially shipped as stable on 17.6.2026, and our own Mastodon Bird UI theme reached its 4.0.0 stable release. We're already running the first nightly of the next cycle, v4.7.0-alpha.1 (today's version).

This update includes today's latest daily build with 56 new commits from upstream since our 13.6.2026 build (mementomods-2026-06-13).

What's new in Mastodon core, these are the changes the Mastodon Team have introduced in the latest nightly version we are running:

✨️ New features

- Mastodon 4.6.0 is officially out. After a long alpha, beta, and RC run, version 4.6 was released as stable on June 17, 2026, bringing Collections, redesigned profiles, email subscriptions, custom filter import and export, and everything else we've been previewing throughout the cycle. Naturally, we've been testing these features over the past few months already.

🔧 Fixes & improvements

- List navigation hotkeys now use Alt + PageUp and Alt + PageDown, the modifier was added so they no longer clash with normal page scrolling.
- Editing a media attachment twice without submitting in between now works.
- The audio player no longer errors out in Safari's Lockdown Mode.
- Hovercards now show up properly in the compose column.
- The report modal heading can now be translated correctly in every language.

♿ Accessibility

- Another round of web UI accessibility fixes landed as part of the final 4.6.0 polish.

📦 Dependency updates

- This round was mostly the 4.6.0 release finalisation, so only minor dependency bumps came with it.

🐦‍⬛ Mastodon Bird UI 4.0.0 (stable)

Our theme reached its 4.0.0 stable release this round, the full modular rewrite built for Mastodon 4.6.0 and forward-compatible with 4.7.0-alpha.1. The big visible change for you is our brand new native favourite animation:

- Favourites now use a hand-rebuilt SVG burst animation instead of the old rotating sprite, recreated frame by frame in the classic Twitter style.
- There are two variants, a heart (shown by default) and a star. You can switch between them in Preferences, Appearance with the "use stars" toggle.
- The favourite counter and hover colour now match the icon, gold for the star and pink for the heart.
- The action-bar hover glow now sits centred on each icon (favourite, reply and boost) instead of drifting towards the counter number.
- Collection preview cards are now indented in feeds so they line up with the post content.
- Fixed the white, unreadable dropdown background on the settings pages (the native select popup).
- Fixed the boost and reply prepend line indentation that regressed after a Mastodon profile change

RE: mementomori.social/@rolle/1167…

I now have a working draft based on the Mastodon main branch (4.6.0-4.7.0-alpha.1): github.com/mementomori-social/…

If you're interested in micro-interactions, we now have them with custom SVGs. Please note I used some AI to trace the sprites I had before, which helped speed up the frame-by-frame work. Feel free to check it out @diondiondion @renchap

Experimenting with new native SVGs to bring into Mastodon core. Instead of the CSS hacks we use in the Mastodon Bird UI, these SVGs provide a more natural solution.

The CSS sprite-based ones are fine and serve their purpose as a theme layered over Mastodon, but I miss a more native approach for the large numbers we have in the posts in our Mastodon fork. The Mastodon team can later decide whether to use these animations, as they will be built against the main branch.

What can I say, I like appealing micro-integrations.

I see Mastodon 4.6.0 was released just a few hours ago, and I'm already getting questions from Mastodon admins. Just a heads-up for Mastodon Bird UI users and admins who have the UI installed: the main branch (stable for 4.5.0) is NOT compatible with Mastodon 4.6.0. The nightly version has been tested with 4.6.0-rc.1, but not yet confirmed for 4.6.0 stable. It should work though, since rc.1, which it was tested with, is only 35 commits behind.

If you are updating your instance now and want Mastodon Bird UI to work, you should use the nightly branch and preferably the official install script we provide for forks. A LOT of the UI has changed, including the new auto color scheme and contrast modes outside of the theme, as well as the major modularization work we did this spring while preparing for 4.6.0.

Custom CSS users should use the CSS files under dist/.

Let me know if you run into any issues with the nightly branch rc-version and I'll fix them soon. Final stable testing is coming at the latest this upcoming weekend.

We've successfully upgraded our Mastodon server to v4.6.0-rc.1+mementomods-2026-06-13, along with Mastodon Bird UI 4.0.0-beta.1.rc nightly updates.

Mastodon hit Release Candidate this round. The 4.6 release is right around the corner.

This update includes today's latest daily build with 85 new commits from upstream since our last build mementomods-2026-06-07.

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

- Import Custom Filters, the import side of last release's export, so you can move your filter rules between accounts and instances
- Bot notifications can be filtered with a new dedicated policy, separate from regular filtered-notifications handling
- Newsletters can now be viewed individually in the admin UI
- Polls and media attachments can be combined in the same post (the old restriction is lifted)
- Media attachment descriptions raised to a 10000 character limit
- Media attachments now carry duration in their ActivityPub representation, so audio and video duration travels with the post over federation
- Collections continue to polish
- Several internal refactors (typing-statuses representation, sundry test coverage on background workers) that should make future patches smoother
- Changelog now points to the right profile-API documentation

Fixes & improvements

- Account hovercard sometimes not triggering, fixed
- "Unlisted collections" profile section was visible to other users, now properly hidden
- Editing a post failed when the post had both a poll and attachments, the validation check is now consistent
- "Remove me from collection" confirmation dialog copy was misleading, cleaned up
- Missing string for custom filter import added
- Missing heading styles in settings area restored
- Loading or errored emoji in a detailed status display name no longer causes a line break
- Sensitive media card display fixed
- Unable to unmark media as sensitive when "always mark media as sensitive" is enabled, fixed
- Sidekiq Elasticsearch connection cleanup made robust
- Avatar and profile header description fields are now serialized over ActivityPub (so alt text actually federates)
- Intermittent failure in `RankedTrend` locales pluck (order-dependent), fixed
- Broken column header layout after the heading refactor, fixed
- Uncontained text overflow in column header, fixed
- Tiny checkboxes and radio buttons in Safari, fixed
- Font size of `Callout` component actions in Safari, fixed
- Alignment of icon and text in `Callout` component, tightened
- Missing boolean check in Admin Reports API, fixed
- Inconsistent `keyboard_shortcuts.translate` string, normalized
- Crash on standalone Wrapstodon and embedded status pages (#39400), fixed
- Poll options ordering below uploads in the compose form, fixed

Accessibility

- Navigation focus management overhauled, focus stays where it should after sidebar interactions
- Alerts ("toasts") are now announced by assistive tech
- Column extra buttons moved out of the h1 column heading
- Patched over the worst a11y issues from the "simple" ruby gems

🐦‍⬛ Mastodon Bird UI 4.0.0-beta.1.rc (nightly)

Side-panel and profile polish, plus some small UX wins:

- Compact navigation items (font-size 17px, gap 7px) on screen heights below 1080px so more nav links fit on a laptop
- Navigation menu scrollbar is now minimal (Firefox thin, WebKit 4px) instead of the dominant OS default
- Trends section top margin removed for a tighter side panel
- Trends drop to 2 items on screen heights below 830px (4 items fit above that)
- Dropdown menus are capped to the viewport height and become scrollable on short or zoomed screens
- Avatar follow badge sits above the display name (z-index) so the first row of the status stays clickable (only for forks that have experimental For you enabled)
- Account timeline filters render above the profile header
