An opt-in nightly job deletes posts from other servers once they are past a retention period and nothing on this server points at them, so the database stops growing without bound. It is off by default and starts as a dry run that deletes nothing; Control Panel → Performance holds its settings. A post that someone here has interacted with is kept, along with its whole thread.
Pick the timeline that fills the Home slot and arrange up to nine more tabs from Following, Accounts, This server, Recommended, All servers, custom feeds, Forums, RSS, and your antennas and lists. The arrangement is stored on the server, so it follows you to every device.
Admins set the Home slot and the tabs that new accounts get, and existing accounts too as long as they have not arranged their own. An option overwrites everyone’s timelines.
You can sign in to, or sign up for, an account on any server that speaks the Misskey or Mastodon API, even without an account here. GoToSocial, Akkoma and Misskey-family servers get profile support, and all your accounts can be refreshed at once.
The Media timeline can be shown as a masonry grid or in an immersive layout, and there is a new Media timeline type. Explore gains a masonry Discover tab and the Pixelfed timeline a Local tab, and sensitive media can be revealed right in the grid.
ALTCHA, a bot protection that runs on your own server and respects privacy, can now be used, and mCaptcha becomes a supported captcha option.
You can follow hashtags, across servers too, and find them in a new Explore tab with a preview on hover. Mutes and blocks apply, antennas can match hashtags, and a hashtag can become a custom timeline with its own name and icon.
Quotes work as they do on Mastodon: from the visibility menu you choose who may quote you, quotes have states, and they federate with Mastodon’s approval and revocation (FEP-044f). Mastodon apps get the same behaviour.
Videos from PeerTube servers play by streaming over HLS, and video posts lead with the player, with their description folded below.
Mastodon apps can schedule posts through the Mastodon API.
Blog posts can carry a content warning, each blog has its own privacy settings, and the Pages and blog editor gains a raw HTML mode.
Sign-ups, and sign-ups waiting to be completed, are now rate-limited per IP address.
Links on your profile are verified the way Mastodon does it, with rel="me".
Admins can add custom CSS for the whole server, and it is served as a real stylesheet.
Admins can choose the time window over which trending hashtags are counted.
Posts now record which app they were posted from, and make it available.
A long dropdown list can be narrowed down by typing.
The layout now follows the direction of the interface language: in a right-to-left language, icons, accent bars and drawn shapes are mirrored throughout.
Servers publish Digital Asset Links, so the Catodon Android app can verify their domain.
