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 Fourwaves?

Fourwaves follows its participant inbox with a week of admin fixes and security hardening.

Fourwaves ships small daily updates. After the Oct 19 participant DM inbox came: admins of organizations with a delegated payment gateway can connect it to events without waiting for approval, sessions without times can have presentations reordered, and a second round of fixes from an internal security audit. One entry is a header-divider style change.

BigBlueButton vs Fourwaves: editorial side-by-side

BigBlueButton logo5.0

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.

MEETINGS
5.0

Fourwaves follows its participant inbox with a week of admin fixes and security hardening.

◆ Current state

Fourwaves ships small daily updates. After the Oct 19 participant DM inbox came: admins of organizations with a delegated payment gateway can connect it to events without waiting for approval, sessions without times can have presentations reordered, and a second round of fixes from an internal security audit. One entry is a header-divider style change.

◆ Where it's heading

The product moves in two lanes: networking features for participants (DM alerts, then the inbox) and less organizer friction around payments, data tables and session scheduling. The security-audit follow-ups suggest more hardening releases are coming.

◆ Prediction

Expect more small organizer-workflow fixes and further security-audit releases. Participant messaging may get moderation or notification controls next.
