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 TrueConf?

Mobile and calendar add-on tweaks dominate; the AI summarization story shipped last month is the real signal.

TrueConf's recent feed is heavy on marketing posts (Top Performer award, market overview piece) and small companion-tool updates — calendar add-ons, the Calendar Connector for Exchange. The substantive product moves are TrueConf 3.2 for Android (voice messages, PIN-protected app access) and, from April, TrueConf AI Server 1.0.2 adding meeting summarization on top of transcription.

BigBlueButton vs TrueConf: editorial side-by-side

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.

5.0

Mobile and calendar add-on tweaks dominate; the AI summarization story shipped last month is the real signal.

◆ Current state

TrueConf's recent feed is heavy on marketing posts (Top Performer award, market overview piece) and small companion-tool updates — calendar add-ons, the Calendar Connector for Exchange. The substantive product moves are TrueConf 3.2 for Android (voice messages, PIN-protected app access) and, from April, TrueConf AI Server 1.0.2 adding meeting summarization on top of transcription.

◆ Where it's heading

The on-premise video conferencing positioning continues to lean on enterprise-friendly extras — calendar integration, security patches, AI summarization that runs on customer-controlled infrastructure. Most of the cadence is incremental; the AI Server work is the only line of investment that could meaningfully change the competitive frame against cloud-first conferencing.

◆ Prediction

Expect AI Server to keep extending (action items, multi-language transcription, integrations with the meeting client UI). The core server and mobile apps will continue their slow stability-and-feature cadence.
