• 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.
