Catodon 26.10.0 "Bongo Cat" released!
This is a big one! Caught up with Misskey 2026.10.0, added ActivityPub C2S API support (we know there are not many clients, but we want to do our part for standardization in the Fediverse), added post languages and language filters, replaced Redis with Valkey and many more…
Read the release notes for a full list of everything we did this month!
Here is a lenghty part of the changelog, click on the link for the full version
changelog
The project is now a Misskey fork
Dependencies brought up to current Misskey. Backend dependencies were brought up to the versions Misskey runs in one sweep, including the AWS S3 client
Many Misskey features merged since the last Sharkey stable
A Misskey server can move to Catodon directly
The MFM parser was updated and patched to read emoji up to Unicode 17.0
Forum & Federation
Forum discovery through the Threadiverse Catalog.
A Lemmy-compatible API that lists this server’s public forums (/api/v3/community/list, /api/v3/community, /api/v3/site)
Cross-posting in forums. A topic posted to several forums is published once and cross-posted to the rest
Blocking a server, as its own thing beside the server mute. It removes the follows in both directions
An ActivityPub client API (client-to-server), so ActivityPub apps can sign in and post, read, follow, react, upload and more.
Reduced-relationship notices. When a moderator blocks a whole server, affected accounts are told which server and how many relationships in each direction it covered, served natively and as Mastodon’s severed_relationships
Mastodon
Word mutes become Mastodon filters. /api/v1/filters and /api/v2/filters
read and write the same filters the settings screen does
Security and correctness ports from Misskey 2026.10.0
Familiar followers (accounts/familiar_followers) and a native
users/familiar-followers, with the privacy rules Mastodon applies.
POST /api/v1/statuses/:id/translate, configuration.translation.enabled
and /api/v1/instance/translation_languages, so Mastodon apps (Tusky, Moshidon, the official Android app) offer translation
Bookmarks and blocked domains can be imported
Lists can be exclusive over the API, matching the native “Hide from home timeline” switch.
A post’s language is now reported and accepted
Smaller parity fixes
Posts, timelines and media
Like and repost counts that match the origin. Popular posts from Mastodon
show the counts Mastodon states
Trending links, server side. Mastodon-style link trends with moderator review
“Also discussed in”. Posts sharing a link now list the other posts discussing it, forum topics first
Watching a post or a thread, with its own notification type and grouped notifications for busy threads.
A focal point on images, honoured by every crop the client makes and
federated as Mastodon’s toot:focalPoint
Language filtering for timelines, with a per-timeline Show all languages override, plus per-post languages and a language pill in the composer.
Hot was reworked so likes and votes carry more weight against age, and no longer lets forum posts crowd out Home, Social, Media, Local and Global.
Double-tap media to like straight from the Media timeline, in the grid and immersive layouts.
Grid and immersive layouts for custom feed tabs, and an Options menu on list and custom feed tabs.
Hide URL previews entirely, a device setting under Settings > Posts and reactions.
A landing page setting deciding what signed-out visitors see at the root.
RSS, Atom and JSON feeds for hashtags (/tags/:tag.rss, .atom, .json).
Moderation
Freeze an account. stop it signing in or acting on any path, with its profile and posts left in place. Suspension is still what takes an account out of view.
IP address and range blocking in Control Panel
An email domain can be held for approval instead of refused outright.
A role can require two-factor authentication, the base role included.
Announcements can be sent by email to every eligible local account, in resumable background batches.
Moderators are notified in-app when someone files a report or signs up, as
Mastodon’s admin.report and admin.sign_up.
Reports carry what the reporter chose : category, rules and attached
posts…and can be forwarded anonymously.
Database connection pool logging, so db.extra.max can be set from evidence rather than guessed.
