BigBlueButton vs mediasoup: at a glance
What is BigBlueButton?
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.
What is mediasoup?
After weeks of one-line subchannel patches, mediasoup rebuilt its RTCP timing model.
The Rust line had been shipping single-PR point releases every few days, nearly all of them subchannel plumbing for DataConsumers over pipe transports plus the occasional crash fix. 0.26.0 breaks that pattern with a seven-PR reworking of how RTCP Sender Reports are generated, moving them off RTP packet arrival time and onto an estimate of when the media was actually captured. The 0.24.0 release earlier in the window also carried real security work — constant-time MAC comparison and fixes for an OOB write and an SCTP integer overflow.

BigBlueButton is polishing the 4.0 beta it already committed to LiveKit, while 3.0 stays the production line.
◆ Current state
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.
◆ Where it's heading
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.
◆ Prediction
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.

6.3MEETINGS
After weeks of one-line subchannel patches, mediasoup rebuilt its RTCP timing model.
◆ Current state
The Rust line had been shipping single-PR point releases every few days, nearly all of them subchannel plumbing for DataConsumers over pipe transports plus the occasional crash fix. 0.26.0 breaks that pattern with a seven-PR reworking of how RTCP Sender Reports are generated, moving them off RTP packet arrival time and onto an estimate of when the media was actually captured. The 0.24.0 release earlier in the window also carried real security work — constant-time MAC comparison and fixes for an OOB write and an SCTP integer overflow.
◆ Where it's heading
Two threads run through this window: finishing the subchannel mechanism so pipe transports behave like direct ones, and tightening timing correctness in the media path. The new RemoteClockOffsetEstimator and RemoteCaptureTimeEstimator classes, plus abs-capture-time rewriting in the simulcast manager, are foundations rather than endpoints — they give the worker a notion of remote capture instants it did not previously have. Expect that foundation to be used by more than Sender Reports.
◆ Prediction
The capture-time estimators look like groundwork for synchronization and delay features beyond Sender Reports; the near-term releases will likely be fixes shaking out the new timing path across simulcast and pipe transports.
