BigBlueButton 4.0.0-rc.1

BigBlueButton 4.0.0-rc.1 is the first release candidate for 4.0. Audio and LiveKit work dominates this iteration: the LiveKit bridge gains multi-room sessions with a membership-based token model (including automatic token refresh), breakout listen-in reaches parity with the FreeSWITCH/mediasoup transfer flow, and the "LiveKit as the audio state source" refactor lands with a long tail of talking-indicator, mute-state, and reconnection fixes. Advanced Filtering becomes pluggable with a second WASM backend (WorkAdventure/DTLN) alongside BBBA. The whiteboard switches to scroll-to-pan with Ctrl+scroll to zoom, the Learning Dashboard now works inside breakout rooms, and the webcam grid can be disabled per server or per meeting. Shared notes collect a round of BlockNote fixes covering math, link editing, export indentation, and the slash menu. Under the hood this candidate upgrades FreeSWITCH to 1.11.3 (from 1.10.12), bbb-webrtc-sfu to 2.25.0-beta.0, bbb-presentation-video to 5.1.0-rc.4, and lettuce-core to 7.7.0. Below is a list of the pull requests in this iteration, grouped by component.

For production use we still recommend the latest release of BigBlueButton 3.0.x.

Upgrade notes

This candidate removes three configuration items that were already dead or deprecated. Administrators upgrading an existing 4.0.x-beta server should check the following:

  • allowDuplicateExtUserid is no longer recognized in bigbluebutton.properties. Use maxUserConcurrentAccesses instead.
  • clientLogoutTimerInMinutes was removed. It was never consumed by the HTML5 client, and its last reader (the /enter endpoint) was removed earlier in 4.0. If you customized /usr/share/bbb-web/WEB-INF/classes/spring/resources.xml in place, remove the <property name="clientLogoutTimerInMinutes" .../> entry as well — bbb-web will otherwise fail to start with NotWritablePropertyException.
  • The logoutTimer parameter on create was removed. It had no effect: the value was stored in bbb-web but never propagated to akka-apps or the client.
  • sharedNotesEditor on create is now validated. Values are stripped of control characters and surrounding whitespace, matched case-insensitively against etherpad / blockNote, canonicalized, and unknown values are now rejected rather than silently accepted.
  • Breakout rooms now always inherit the parent meeting's effective meetingKeepEvents value. An explicit meetingKeepEvents parameter and the server-wide defaultKeepEvents fallback apply only to top-level meetings.

New client settings in this iteration: public.kurento.pagination.gridEnabled (default true) and public.media.audio.audioWasmProcessing.provider (bbba default, or workadventureDtln). The webcam grid can also be turned off per meeting with disabledFeatures=webcamGrid.

Release name

Passing -v noble-400 to https://github.com/bigbluebutton/bbb-install/blob/v4.0.x-release/bbb-install.sh will always install the latest released BigBlueButton 4.0 version.

If for some reason you would like to install this specific release, pass -v noble-400-4.0.0-rc.1.

We still recommend using -v noble-400 as this repository is continually updated with each BigBlueButton 4.0 release.
