Fourwaves vs Greenlight: at a glance
What is Fourwaves?
Fourwaves is in a polish cycle: custom-domain fixes, accessibility rules and password UX.
Fourwaves runs an event platform for academic conferences and ships small changes every few days. Since late September the work has covered participant communication (DM alerts, preferences, richer discussion emails) and organizer setup, especially custom domains: one-click DNS copy, root domains through A records, and a fix for language resets on custom-domain events. The latest items are accessibility and account hygiene.
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.

6.3MEETINGS
Fourwaves is in a polish cycle: custom-domain fixes, accessibility rules and password UX.
◆ Current state
Fourwaves runs an event platform for academic conferences and ships small changes every few days. Since late September the work has covered participant communication (DM alerts, preferences, richer discussion emails) and organizer setup, especially custom domains: one-click DNS copy, root domains through A records, and a fix for language resets on custom-domain events. The latest items are accessibility and account hygiene.
◆ Where it's heading
The cadence is steady and incremental, with no new product surface since the September pricing change. Custom-domain support is being hardened case by case, which suggests more organizers are running events on their own domains. Participant-side work has shifted from engagement features to account and form basics.
◆ Prediction
Expect more small custom-domain and accessibility fixes on the same few-day cadence; the entries do not point to a larger feature or another pricing change.
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.
