Krisp turned noise cancellation into a contact-center AI stack — and now defends it against deepfakes.
A side-by-side editorial comparison of Dendrite and Signal Desktop — release velocity, themes, recent moves, and the top alternatives to consider.
A forked, relicensed Dendrite spent its first year catching up on Matrix protocol and security debt
The window opens with the first release after forking from matrix-org/dendrite under AGPLv3, which fixed long-standing state-reset bugs and added I2P and Onion listening. What follows is a security release closing a server-side request forgery vulnerability, then a release adding room version 12 support and two MSC implementations, and finally two quick patches for unresponsiveness, v12 room joins and malformed PDUs blocking whole transactions.
Signal is quietly rebuilding group governance while polls and pins push into everyday chats
The desktop beta line is shipping a steady run of user-facing social features: polls extended to one-to-one chats, admin deletion of recent group messages, an explicit End Group action, disappearing call events, and reorderable sticker packs. Each release carries one or two concrete changes rather than a bundle. Pinned chats also moved from 4 to 10.

This is a fork proving it can carry a homeserver. The order is telling: license and state correctness first, then a CVE, then protocol currency with room version 12, then the operational bugs that surface once people actually run it. Several fixes carry outside contributor credits, which is the fork's clearest sign of life.
Expect continued protocol catch-up on newer MSCs and room versions plus operational fixes, since federation compatibility is the constraint that sets this project's agenda.

Two threads run through the window. One is group administration — admins gained message deletion and a way to formally close a group, turning groups from open-ended threads into objects with a lifecycle. The other is bringing lightweight social mechanics from group chats down into individual ones. Both extend the surface without touching Signal's privacy model.
Expect the group-lifecycle work to continue with more admin controls, and for the features currently landing in desktop beta to promote into the stable line on the same weekly-to-biweekly rhythm.
