BigBlueButton vs Greenlight: 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 Greenlight?
Greenlight 3.9 makes URL_HOST mandatory, forcing admin action on every self-hosted deployment.
Greenlight, the BigBlueButton web frontend, is in a security-maintenance phase. The 3.8.x series was dominated by gem updates and language patches; 3.9.0 introduces multiple undisclosed security fixes alongside a breaking change that requires URL_HOST to be set in .env or the application will refuse to start. A follow-up hotfix landed hours later to address a startup crash introduced in the release.
BigBlueButton vs Greenlight: editorial side-by-side
BigBlueButton
5.0MEETINGS
BigBlueButton 4.0 rc.5 drops Etherpad and makes BlockNote the only notes editor.
◆ 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.
Greenlight
5.0MEETINGS
Greenlight 3.9 makes URL_HOST mandatory, forcing admin action on every self-hosted deployment.
◆ Current state
Greenlight, the BigBlueButton web frontend, is in a security-maintenance phase. The 3.8.x series was dominated by gem updates and language patches; 3.9.0 introduces multiple undisclosed security fixes alongside a breaking change that requires URL_HOST to be set in .env or the application will refuse to start. A follow-up hotfix landed hours later to address a startup crash introduced in the release.
◆ Where it's heading
Greenlight's release cadence is maintenance-driven: security response and dependency updates rather than feature work. The 3.9.0 breaking change is the project tightening deployment requirements, likely in response to misconfiguration risks identified in security audits. The rapid hotfix points to limited pre-release testing capacity on the project.
◆ Prediction
The undisclosed 3.9.0 security fixes will be disclosed within weeks and likely explain the URL_HOST mandate — deployments without it were probably vulnerable to host header injection or similar configuration-dependent attacks.
