BigBlueButton vs PeerTube: 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 PeerTube?
PeerTube makes moderation federated: instances can now subscribe to each other's blocklists
The 8.3.0 candidate opens a new line and is by far the largest release in this window. Instances can subscribe to remote blocklists and watched-word lists that periodically re-sync, automatically muting accounts and servers and re-tagging existing videos and comments in the background, and an instance can publish its own blocklist as a public log for others to consume. A dense security block lands with it — cross-IP account login lockout, per-account rate limits on abuse and comment creation, OTP encryption moved to GCM, SVG sanitisation. The preceding 8.2 train was narrower: download bandwidth throttling and stabilisation.

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.

PeerTube makes moderation federated: instances can now subscribe to each other's blocklists
◆ Current state
The 8.3.0 candidate opens a new line and is by far the largest release in this window. Instances can subscribe to remote blocklists and watched-word lists that periodically re-sync, automatically muting accounts and servers and re-tagging existing videos and comments in the background, and an instance can publish its own blocklist as a public log for others to consume. A dense security block lands with it — cross-IP account login lockout, per-account rate limits on abuse and comment creation, OTP encryption moved to GCM, SVG sanitisation. The preceding 8.2 train was narrower: download bandwidth throttling and stabilisation.
◆ Where it's heading
The through-line from 8.2 to 8.3 is that PeerTube keeps building for the instance admin rather than the viewer, but the unit of defence has changed. 8.2 handed a single admin local controls — per-instance and per-IP download throttles aimed at scraping botnets. 8.3 makes those defences shareable, so moderation decisions propagate between instances on their own, while new plugin auto-tagger registration lets classification be automated too. The security list reads like a post-audit sweep rather than incremental hardening.
◆ Prediction
Expect 8.3 to spend its remaining candidates on stabilisation as 8.2 did, with the manual migration script and the multi-minute startup migration the main upgrade risks to shake out. Whether subscribed lists get curation or trusted-publisher tooling isn't visible in these entries.
