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 Lark?

Lark concentrates monthly updates on Base — automation branching, mobile dashboards, layout reset — while the collaboration suite holds steady.

Lark's monthly update cadence is centered on Lark Base, the suite's no-code data tool. V7.65 adds advanced formatting and branch settings to Base automations; V7.64 makes dashboard charts interactive on the mobile app; V7.62 ships one-click reset for custom Base record detail page layouts; V7.63 introduces AHA PC Doctor as an in-app self-service troubleshooter. V7.60 polishes image highlights in comments and V7.59 expands message-sending options in Base automated workflows.

BigBlueButton vs Lark: editorial side-by-side

BigBlueButton logo6.3

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.

Lark concentrates monthly updates on Base — automation branching, mobile dashboards, layout reset — while the collaboration suite holds steady.

◆ Current state

Lark's monthly update cadence is centered on Lark Base, the suite's no-code data tool. V7.65 adds advanced formatting and branch settings to Base automations; V7.64 makes dashboard charts interactive on the mobile app; V7.62 ships one-click reset for custom Base record detail page layouts; V7.63 introduces AHA PC Doctor as an in-app self-service troubleshooter. V7.60 polishes image highlights in comments and V7.59 expands message-sending options in Base automated workflows.

◆ Where it's heading

Lark is investing heavily in Base's automation depth and admin ergonomics — branch settings, granular automation triggers, mobile-first dashboard interaction, layout management. Earlier versions in the index (V7.51 AI in Base, V7.55 new workspaces, V7.58 condition-group permissions) confirm Base as the consistent center of feature work. The broader collaboration suite (chat, docs, calendar) is held steady while Base evolves.

◆ Prediction

Expect more agentic AI inside Base (extending the V7.51 thread), continued mobile parity with desktop dashboards, and deeper automation features — multi-step branching with conditions, more third-party connectors. Self-service support (PC Doctor) is likely to expand to mobile and Mac.
