BigBlueButton vs Bizzabo: at a glance
What is BigBlueButton?
BigBlueButton 4.0 rc.5 drops Etherpad and makes BlockNote the only notes editor.
BigBlueButton 4.0.0-rc.5 removes Etherpad, so upgrading uninstalls bbb-etherpad and bbb-pads and leaves BlockNote as the only shared-notes editor. It also moves Node components to Node.js 24, switches the client to the 1.0 pre-release plugin SDK, and redesigns the poll and quiz panels. It follows two security-only candidates, and the project still recommends 3.0.x for production.
What is Bizzabo?
Bizzabo's public feed is an SEO content engine, not a changelog.
Every entry in this window is marketing content — planning guides, listicles, and ROI explainers aimed at enterprise event teams. The recurring argument is that events must prove pipeline impact, and that Bizzabo supplies the attribution and registration infrastructure to do it. No product releases appear in the feed at all.

◆ Current state
BigBlueButton 4.0.0-rc.5 removes Etherpad, so upgrading uninstalls bbb-etherpad and bbb-pads and leaves BlockNote as the only shared-notes editor. It also moves Node components to Node.js 24, switches the client to the 1.0 pre-release plugin SDK, and redesigns the poll and quiz panels. It follows two security-only candidates, and the project still recommends 3.0.x for production.
◆ Where it's heading
The 4.0 cycle is removing legacy components one by one: SIP.js audio went in beta.4, and Etherpad goes now. Between the removals, security-only candidates harden the new LiveKit audio and BlockNote notes surfaces. The plugin SDK reaching a 1.0 pre-release suggests the extension API is being frozen for GA.
◆ Prediction
Expect at least one more candidate to settle the plugin SDK 1.0 change and Etherpad removal before 4.0.0 GA. The pace of security advisories makes the exact timing unclear.
Bizzabo
5.0MEETINGS
Bizzabo's public feed is an SEO content engine, not a changelog.
◆ Current state
Every entry in this window is marketing content — planning guides, listicles, and ROI explainers aimed at enterprise event teams. The recurring argument is that events must prove pipeline impact, and that Bizzabo supplies the attribution and registration infrastructure to do it. No product releases appear in the feed at all.
◆ Where it's heading
The content is converging on measurement: attribution models, ROI reporting, and mobile app adoption framed as data capture. That signals where the company wants to compete — against event platforms that stop at logistics — but it is positioning rather than shipping. Direction cannot be read from this feed with any confidence.
◆ Prediction
Expect more of the same measurement-themed content. Any real product signal would have to come from a channel other than this feed, which carries no release notes.
