mediasoup has moved off data-channel plumbing and into the media path — timing first, now layer selection.
A side-by-side editorial comparison of BigBlueButton and Jitsi — release velocity, themes, recent moves, and the top alternatives to consider.
BigBlueButton is polishing the 4.0 beta it already committed to LiveKit, while 3.0 stays the production line.
The 4.0 beta series is in its fifth iteration and the hard architectural decisions are behind it — LiveKit became the default media stack in beta.4 with the legacy SIP.js bridge deleted, BlockNote became the default shared notes engine, and the JVM moved to Java 21. Beta.5 is consolidation: a mobile layout overhaul with paginated webcams and landscape side-by-side camera and presentation, automatic light/dark switching, a dedicated Audio settings tab with push-to-talk, and better BBB-to-LiveKit state reconciliation on reconnect. Packaging gained a bbbctl admin tool and a bbb-coturn package, with bbb-etherpad and bbb-pads now optional. The project still recommends 3.0.x for production.
Jitsi rebuilds its transcription stack and keeps investing in large-call performance.
Jitsi (Jitsi Meet plus its open-source backend) is an engineering-led project whose blog doubles as its changelog. Recent posts mix genuine infrastructure work, a rebuilt transcription architecture, receiver audio subscriptions, AV1 codec adoption, with community items like Google Summer of Code cohorts.

The 4.0 line is converging toward a release candidate, and the work has shifted from replacing subsystems to making the new ones survive real conditions — reconnects, phones, and administrator tooling. Making etherpad and pads optional alongside a security advisory that urges API secret rotation points at shrinking the default install's attack surface. The parallel 3.0.x train continues shipping security patches, so the ecosystem is carrying two branches until 4.0 stabilises.
Expect beta.6 or a release candidate to focus on the LiveKit reconnection and mobile paths that beta.5 only started, since those are the areas where a self-hosted media migration typically breaks. The optional-package work suggests a slimmer default deployment is being prepared for the 4.0 release.
Jitsi (Jitsi Meet plus its open-source backend) is an engineering-led project whose blog doubles as its changelog. Recent posts mix genuine infrastructure work, a rebuilt transcription architecture, receiver audio subscriptions, AV1 codec adoption, with community items like Google Summer of Code cohorts.
The technical arc is toward scaling and modernizing the media stack: selective audio subscriptions, SSRC rewriting, AV1, and now a from-scratch transcription architecture replacing the decade-old Jigasi approach. Jitsi is steadily shedding legacy components in favor of architecture that handles large calls and real-time features more efficiently.
The new transcription architecture likely lands broader real-time features (live captions, translation hooks) over the coming releases; expect continued media-pipeline optimization for large meetings.
