BigBlueButton vs Dacast: at a glance
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.
What is Dacast?
Dacast's changelog is a streaming-education blog with no releases in it.
Dacast is a video streaming and OTT delivery platform, and every entry in the current window is editorial content: CDN and adaptive-bitrate guides for education, remote streaming without wired connectivity, sports OTT strategy, an IPTV versus OTT comparison, simulcast instructions, and a church streaming buyer's guide. All are bylined to the Dacast editorial team and reviewed by an executive, and none announce a product change.

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.
Dacast
0.0MEETINGS
Dacast's changelog is a streaming-education blog with no releases in it.
◆ Current state
Dacast is a video streaming and OTT delivery platform, and every entry in the current window is editorial content: CDN and adaptive-bitrate guides for education, remote streaming without wired connectivity, sports OTT strategy, an IPTV versus OTT comparison, simulcast instructions, and a church streaming buyer's guide. All are bylined to the Dacast editorial team and reviewed by an executive, and none announce a product change.
◆ Where it's heading
The consistent shape is vertical-by-vertical buyer education — education, sports, worship, remote production — each mapped to a use case Dacast sells into. That is a go-to-market pattern, not a product one, and the platform's actual development is not visible through this feed.
◆ Prediction
Expect more vertical guides on the same rotation, refreshed with a current year in the title. No prediction about the product itself is supportable from these entries.
