What is BigBlueButton?

BigBlueButton 4.0 enters release candidate with LiveKit fully replacing the legacy audio stack.

BigBlueButton is in its final stretch to 4.0 GA, with three release candidates shipping in September 2026. The 4.0 release is a near-complete architectural rebuild: LiveKit has replaced SIP.js and mediasoup as the default media transport, BlockNote replaced the old shared notes engine, and the mobile layout was overhauled. RC2 shipped security fixes for a cross-meeting presentation injection vulnerability, urging immediate admin updates.

BigBlueButton vs Slack (Huddles): editorial side-by-side

BigBlueButton logo6.3

BigBlueButton 4.0 enters release candidate with LiveKit fully replacing the legacy audio stack.

◆ Current state

BigBlueButton is in its final stretch to 4.0 GA, with three release candidates shipping in September 2026. The 4.0 release is a near-complete architectural rebuild: LiveKit has replaced SIP.js and mediasoup as the default media transport, BlockNote replaced the old shared notes engine, and the mobile layout was overhauled. RC2 shipped security fixes for a cross-meeting presentation injection vulnerability, urging immediate admin updates.

◆ Where it's heading

The LiveKit migration that began in 3.x security patches has culminated in rc.1's 'LiveKit as audio state source' refactor — the legacy audio path is gone. Multi-room sessions with membership-based tokens and automatic token refresh enable scenarios (breakout listen-in, large conferences) that the old bridge couldn't cleanly support. A 4.0 GA release is imminent given the RC cadence.

◆ Prediction

4.0 GA will ship within 2-3 weeks based on the RC pace. Post-GA focus will shift to hardening the LiveKit multi-room session model and expanding BlockNote capabilities (Markdown export landed in beta.4; more collaborative editing features likely next). The successful migration may influence other open-source video conferencing projects still running legacy SFU stacks.

Slack (Huddles) logo0.0

This feed is an archive of old Slack desktop releases, not current product news.

◆ Current state

The window covers Slack desktop app versions 2.6.3 through 2.8.2 — keychain credential storage, resumable file downloads, keyboard navigation, French, Spanish and German localization, and a run of Electron security updates and input-method fixes. These are historical client releases, captured with version-only titles.

◆ Where it's heading

Read as a sequence, the arc is a desktop client maturing: security and platform updates, internationalization, and repeated regression fixes to Japanese input. It says nothing about where Slack is heading now, because the entries predate the product's current direction.

◆ Prediction

No forward-looking read is supportable from these entries. Current signal would require the feed to point at Slack's present release notes rather than this archived client changelog.
