Matrix vs Signal Desktop: at a glance
What is Matrix?
Matrix 2.0 is nearly through the spec process, and governments are the audience
The Matrix spec process has moved quickly since the 2026 conference. MatrixRTC, its LiveKit transport, the voice and video calling application, sticky events and the sliding sync extensions were all accepted in the 30 October update, leaving MSC4480 and MSC4075 outstanding before Matrix 2.0. The conference drew more than 340 people, with civil servants from 15 nations and organizations. Talks came from FITKO, DINUM, UNICC and NATO, among others.
What is Signal Desktop?
Signal Desktop's 8.35 beta returns to fix-only notes after contact sharing.
Signal Desktop ships a beta roughly weekly, and most builds since September carry only generic fix notes. v8.35.0-beta.1 is another of those, following v8.34.0-beta.1, which added contact sharing from desktop and better audio device handling, and v8.32.0-beta.1, which extended the unread filter into folders and search.

◆ Current state
The Matrix spec process has moved quickly since the 2026 conference. MatrixRTC, its LiveKit transport, the voice and video calling application, sticky events and the sliding sync extensions were all accepted in the 30 October update, leaving MSC4480 and MSC4075 outstanding before Matrix 2.0. The conference drew more than 340 people, with civil servants from 15 nations and organizations. Talks came from FITKO, DINUM, UNICC and NATO, among others.
◆ Where it's heading
Two tracks now run together: finishing a protocol generation that puts real-time calling in the specification, and turning European digital-sovereignty policy into adoption and funding. The Foundation's own message is that usage is outrunning support. Only DINUM among government agencies is a member, so membership, certification and training are being explored as revenue. A federated calendaring proposal shows the spec work is already looking past 2.0.
◆ Prediction
The spec team says Matrix 2.0 follows shortly after the two remaining MSCs are merged, so that declaration is the next major event. Foundation funding is the less certain thread: the entries list ideas but no commitments.
Signal Desktop
5.0COMMS
Signal Desktop's 8.35 beta returns to fix-only notes after contact sharing.
◆ Current state
Signal Desktop ships a beta roughly weekly, and most builds since September carry only generic fix notes. v8.35.0-beta.1 is another of those, following v8.34.0-beta.1, which added contact sharing from desktop and better audio device handling, and v8.32.0-beta.1, which extended the unread filter into folders and search.
◆ Where it's heading
The desktop app is closing gaps with mobile one feature at a time, separated by maintenance betas. Visible features arrive about every two to three builds.
◆ Prediction
The next feature beta is likely within one or two builds, based on the cadence since October. The entries don't indicate what it will contain.
