What is BigBlueButton?

BigBlueButton 4.0 enters release candidate with LiveKit fully replacing the legacy audio stack.

BigBlueButton is in its final stretch to 4.0 GA, with three release candidates shipping in September 2026. The 4.0 release is a near-complete architectural rebuild: LiveKit has replaced SIP.js and mediasoup as the default media transport, BlockNote replaced the old shared notes engine, and the mobile layout was overhauled. RC2 shipped security fixes for a cross-meeting presentation injection vulnerability, urging immediate admin updates.

What is Element Call?

Element Call is removing its legacy architecture — the federated multi-SFU model is now the only option.

Element Call has spent the last two months removing compatibility scaffolding: MatrixRTC legacy mode (v0.25.0) and .well-known transport discovery (v0.24.0) are both gone. Every participant now connects to their homeserver's SFU with no fallback to the old negotiated single-SFU model. React Compiler is enabled for rendering performance, and media quality settings got a dedicated UI in v0.24.0. The RC release cadence is high while stable releases remain patch-focused.

BigBlueButton 4.0 enters release candidate with LiveKit fully replacing the legacy audio stack.

◆ Current state

BigBlueButton is in its final stretch to 4.0 GA, with three release candidates shipping in September 2026. The 4.0 release is a near-complete architectural rebuild: LiveKit has replaced SIP.js and mediasoup as the default media transport, BlockNote replaced the old shared notes engine, and the mobile layout was overhauled. RC2 shipped security fixes for a cross-meeting presentation injection vulnerability, urging immediate admin updates.

◆ Where it's heading

The LiveKit migration that began in 3.x security patches has culminated in rc.1's 'LiveKit as audio state source' refactor — the legacy audio path is gone. Multi-room sessions with membership-based tokens and automatic token refresh enable scenarios (breakout listen-in, large conferences) that the old bridge couldn't cleanly support. A 4.0 GA release is imminent given the RC cadence.

◆ Prediction

4.0 GA will ship within 2-3 weeks based on the RC pace. Post-GA focus will shift to hardening the LiveKit multi-room session model and expanding BlockNote capabilities (Markdown export landed in beta.4; more collaborative editing features likely next). The successful migration may influence other open-source video conferencing projects still running legacy SFU stacks.

Element Call is removing its legacy architecture — the federated multi-SFU model is now the only option.

◆ Current state

Element Call has spent the last two months removing compatibility scaffolding: MatrixRTC legacy mode (v0.25.0) and .well-known transport discovery (v0.24.0) are both gone. Every participant now connects to their homeserver's SFU with no fallback to the old negotiated single-SFU model. React Compiler is enabled for rendering performance, and media quality settings got a dedicated UI in v0.24.0. The RC release cadence is high while stable releases remain patch-focused.

◆ Where it's heading

The architecture is settled: federated multi-SFU, homeserver-anchored, no legacy bridges. The breaking changes are pruning maintenance surface rather than adding capability. The next period is likely refinement — call quality controls, edge-case stability, and mobile experience polish — within the established architecture. Element Call's trajectory is now governed by the Matrix ecosystem roadmap more than its own feature backlog.

◆ Prediction

Stable releases catching up to the RC channel, with polish on the media quality controls from v0.24.0 and mobile layout improvements. Homeserver-level call routing policies are a plausible next capability now that the SFU model is uniform across all deployments.
