BigBlueButton vs mediasoup: at a glance
What is BigBlueButton?
BigBlueButton's 4.0 beta defaults to a Unified layout and ships a WASM audio processor.
BigBlueButton is running two parallel tracks: aggressive maintenance on the 3.0 line (six security-and-improvement releases between January and March, with LiveKit audio stabilization the recurring theme) and a 4.0 beta cycle that just hit beta.3 with substantial UX work. v4.0.0-beta.3 makes the Unified layout the default, adds a WASM-based audio processor on the mic stream, introduces user search, a 3-state presenter lock policy, pinned moderator messages, a viewer 'Request to Become Presenter' flow, and Ubuntu 24.04 support.
What is mediasoup?
mediasoup stays in maintenance mode, hardening its SFU worker internals
mediasoup is a low-level WebRTC SFU library that other products embed rather than an end-user app. The only recent release is a Rust-binding patch focused on worker-level correctness: transport tuple hashing, sequence management, and STUN parsing. There is no feature-level movement visible here.

BigBlueButton's 4.0 beta defaults to a Unified layout and ships a WASM audio processor.
◆ Current state
BigBlueButton is running two parallel tracks: aggressive maintenance on the 3.0 line (six security-and-improvement releases between January and March, with LiveKit audio stabilization the recurring theme) and a 4.0 beta cycle that just hit beta.3 with substantial UX work. v4.0.0-beta.3 makes the Unified layout the default, adds a WASM-based audio processor on the mic stream, introduces user search, a 3-state presenter lock policy, pinned moderator messages, a viewer 'Request to Become Presenter' flow, and Ubuntu 24.04 support.
◆ Where it's heading
BBB is preparing for the 4.0 line as the long-term successor to 3.0. The Unified layout (introduced opt-in in 3.0.19 back in January) is becoming the default; audio infrastructure is being modernized via WASM. The pattern of security patches every two to four weeks on 3.0 signals strong institutional-deployment support discipline. Beta cadence on 4.0 suggests GA is still some months out.
◆ Prediction
Expect a few more 4.0 beta iterations before release candidates, with feature work converging toward GA in Q3 2026. The 3.0 line will continue to receive security-focused maintenance — institutional users (universities, training orgs) tend to lag on majors, so the dual-track will continue past 4.0 GA.

2.5MEETINGS
mediasoup stays in maintenance mode, hardening its SFU worker internals
◆ Current state
mediasoup is a low-level WebRTC SFU library that other products embed rather than an end-user app. The only recent release is a Rust-binding patch focused on worker-level correctness: transport tuple hashing, sequence management, and STUN parsing. There is no feature-level movement visible here.
◆ Where it's heading
Development continues to track WebRTC protocol details rather than expand surface area. Replacing a uint64 hash with a structured TupleKey and adding handling for the STUN NOMINATION attribute show the project keeping pace with ICE/STUN edge cases as they appear upstream.
◆ Prediction
Expect more of the same: small, protocol-driven patches to the worker as WebRTC specs and real-world traffic surface collisions or new attributes. The single entry here doesn't support a prediction about larger feature direction.
