rtpengine backports the same DTLS and socket fixes across four maintenance branches at once.
A side-by-side editorial comparison of BigBlueButton and Nextcloud Talk Desktop — release velocity, themes, recent moves, and the top alternatives to consider.
BigBlueButton 4.0 rc.4 is a security-only release as the LiveKit stack hardens.
BigBlueButton 4.0.0-rc.4 contains security fixes only, including a command injection through destination_number, unauthenticated access to a meeting's audio conference and shared notes reachable by non-members. It follows rc.2, also security-only, and rc.3, which focused on LiveKit reconnection and test stability. The project still recommends 3.0.x for production.
Nextcloud Talk Desktop 2.3.2 ships Talk v25 stable with E2EE call audio fix
Nextcloud Talk Desktop v2.3.2 delivers Talk v25.0.0 in the stable channel, alongside fixes for a critical E2EE call regression (no audio/video), Windows ARM64 crashes, Linux tray icon rendering, and Flatpak drag-and-drop on some distributions. Electron is updated to 44.3.0. The v2.3.x cycle moved from Talk v25 RC1 to stable in about three weeks through two beta iterations.

The 4.0 cycle has moved from architecture (LiveKit as the only media path, BlockNote notes, Java 21) to hardening. Two security-only candidates in a month show the new LiveKit audio and notes surfaces are getting close scrutiny before GA.
Expect 4.0.0 GA once the release-candidate cadence quiets, likely preceded by at least one more rc. The steady flow of advisories makes the exact timing unclear.

The desktop app tracks Talk server releases closely, with each major Talk version getting a corresponding desktop stable. The enterprise footprint is expanding: managed configuration via Windows GPO and macOS NSUserDefaults (shipped in v2.2.1) lets organizations deploy pre-configured servers at the OS policy level — a capability that was previously missing. ARM64 Windows support is now functional after the v2.3.2 crash fix.
The next cycle will center on Talk v25.x point releases and continued cross-platform reliability work, particularly for Linux Wayland and Flatpak. Enterprise deployment features (managed config, CLI account presets) may see further expansion given the recent investment.
