Catodon

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! ​​ #catodon

Catodon 26.9.0 stable released!

Catodon 26.9.0 - what's new

• Multi-server accounts - you can now sign in or sign up on any other Misskey- or Mastodon-API server, not just this one. Works with Pixelfed GoToSocial, Akkoma, and the Misskey family too.
• Customizable timelines - pick what fills your Home slot and arrange up to 9 tabs from Following, your other accounts, forums, RSS, antennas, lists, and more. Syncs across devices.
• New media timeline with a masonry layout.
• Quote posts that are compatible with Mastodon's implementation, federated via FEP-044f.
• Hashtag following - follow tags natively, federated, with a hover preview and Custom feed support.
• PeerTube video streaming - remote PeerTube videos now stream over HLS instead of just linking out.
• Blogs got content warnings and per-blog privacy settings, plus a raw HTML mode in the editor.
• Right-to-left language support - the whole UI now mirrors properly for RTL languages.
• ALTCHA added as the default self-hosted, privacy-friendly captcha option.
• A big security pass: closed several SSRF holes (URL previews, RSS fetching, JSON-LD verification), fixed a password-reset bug that let a moderator reset another admin's password, tightened 2FA/TOTP replay protection, patched a few data-visibility leaks, and pulled in ~90 hardening fixes adapted from upstream Sharkey. Nothing here was known to be actively exploited, but if you're running your own instance, update promptly.
• Plus a long tail of smaller fixes: broken federation edge cases (forums, blog permalinks, PeerTube lookups), a mention-notification race, sharper remote media, and assorted UI polish.
