BigBlueButton vs Digital Samba: at a glance
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 Digital Samba?
Digital Samba's public feed is a WebRTC explainer blog, not a changelog.
Every entry in this window is editorial content rather than a release: WebRTC debugging walkthroughs, an SVC-versus-simulcast comparison, an E2EE threat breakdown, a build-versus-buy cost essay, and recaps of European tech events. The most recent post covers transcription and AI meeting summaries via API, but it reads as a buyer-education article rather than a shipping announcement. No product changelog is reaching the crawler, so the capability surface is invisible here.

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.
Digital Samba
5.0MEETINGS
Digital Samba's public feed is a WebRTC explainer blog, not a changelog.
◆ Current state
Every entry in this window is editorial content rather than a release: WebRTC debugging walkthroughs, an SVC-versus-simulcast comparison, an E2EE threat breakdown, a build-versus-buy cost essay, and recaps of European tech events. The most recent post covers transcription and AI meeting summaries via API, but it reads as a buyer-education article rather than a shipping announcement. No product changelog is reaching the crawler, so the capability surface is invisible here.
◆ Where it's heading
The topic mix is a positioning strategy aimed squarely at EU digital sovereignty. Regulatory pieces on the Cloud and AI Development Act and EU open-source strategy sit next to deep protocol content, which targets healthcare, government and education buyers who must justify where media and AI inference physically happen. The technical explainers do the second job of reaching engineers evaluating build-versus-buy.
◆ Prediction
Expect continued sovereignty and compliance content paced to EU regulatory milestones, alongside protocol explainers. Any read on actual product velocity would need a real changelog source, since this feed does not carry one.
