Greenlight vs Fourwaves: at a glance
What is Greenlight?
Greenlight 3.9.1 fixes a critical upload flaw and tells admins to rotate secrets.
Greenlight, the BigBlueButton web frontend, released 3.9.1 on Nov 5 to fix a critical flaw: through a Rails Active Storage issue, a user able to upload an avatar or presentation could read or write files on the server. The fix comes from Rails 8.0.5.2's stricter ImageMagick policy, and instances storing uploads on local disk are told to rotate SECRET_KEY_BASE, database, BigBlueButton and other credentials.
What is Fourwaves?
Fourwaves doubles Free plan submissions to 50 and reworks reviewer assignment.
Fourwaves ships small dated updates most days. November 11 raised the Free plan from 25 to 50 submissions, and November 12 added a four-step Assign reviewers window. Earlier in November it brought offline mobile check-in for Pro organizers and saved email templates for Advanced and Pro.

◆ Current state
Greenlight, the BigBlueButton web frontend, released 3.9.1 on Nov 5 to fix a critical flaw: through a Rails Active Storage issue, a user able to upload an avatar or presentation could read or write files on the server. The fix comes from Rails 8.0.5.2's stricter ImageMagick policy, and instances storing uploads on local disk are told to rotate SECRET_KEY_BASE, database, BigBlueButton and other credentials.
◆ Where it's heading
The project remains in security maintenance: gem updates, a breaking URL_HOST requirement in 3.9.0 and now an urgent patch. Feature work has been rare since the invitation changes in April.
◆ Prediction
Expect more dependency-driven security releases; new features look unlikely from the recent pattern.
Fourwaves
5.0MEETINGS
Fourwaves doubles Free plan submissions to 50 and reworks reviewer assignment.
◆ Current state
Fourwaves ships small dated updates most days. November 11 raised the Free plan from 25 to 50 submissions, and November 12 added a four-step Assign reviewers window. Earlier in November it brought offline mobile check-in for Pro organizers and saved email templates for Advanced and Pro.
◆ Where it's heading
Most releases go to organizer tools for running the event and the review process, with features gated to paid plans. The Free plan increase is the first move in this run that widens the entry tier rather than adding to paid ones.
◆ Prediction
Expect more steps in the submission and review workflow to follow the new reviewer window; whether the Free plan change is part of a wider pricing revision is unclear from the entries.
