What is Fourwaves?

Fourwaves is closing the gaps around its payments layer and its form editor at the same time.

Fourwaves publishes a near-daily, one-line changelog covering small changes to the conference organiser's admin surface. The August window is dominated by payments and money administration: transaction filtering by organisation and by payment gateway, the Free plan surfaced in the upgrade checkout, and Authorize.net added as a supported processor. The two newest entries move elsewhere — self-service account creation from the sign-in page, and a guard that blocks deleting fields, sections, or choices still referenced elsewhere in an event, with a warning naming what depends on them.

What is Greenlight?

BigBlueButton's front door is in pure maintenance mode: security patches, gem bumps, translations.

Greenlight ships on a security-driven cadence rather than a feature one. The last four releases in the 3.8.2.x line are almost entirely gem updates, security backports and language file refreshes, with occasional small admin affordances like HTML in the maintenance banner or an env var to bypass host configuration. The one substantive batch in the window is 3.8.1's invitation flow work.

Fourwaves vs Greenlight: editorial side-by-side

MEETINGS
5.0

Fourwaves is closing the gaps around its payments layer and its form editor at the same time.

◆ Current state

Fourwaves publishes a near-daily, one-line changelog covering small changes to the conference organiser's admin surface. The August window is dominated by payments and money administration: transaction filtering by organisation and by payment gateway, the Free plan surfaced in the upgrade checkout, and Authorize.net added as a supported processor. The two newest entries move elsewhere — self-service account creation from the sign-in page, and a guard that blocks deleting fields, sections, or choices still referenced elsewhere in an event, with a warning naming what depends on them.

◆ Where it's heading

The work is aimed at multi-event organisations rather than single-conference organisers; transaction filtering and a second payment processor only matter if you run several events through shared gateways. The referential-integrity guard on form fields points at the same maturity problem from the other side — events configured deeply enough that deleting a field silently breaks something downstream, which is a complaint you only get once customers build complex forms. Individually each change is minor; together they describe a platform being made to hold more events per customer.

◆ Prediction

Expect the payments thread to continue — further gateway options or per-organisation payment configuration are the natural next step now that transactions can be filtered by gateway. The date-stamped daily format suggests the cadence holds regardless of the size of what ships.

2.5

BigBlueButton's front door is in pure maintenance mode: security patches, gem bumps, translations.

◆ Current state

Greenlight ships on a security-driven cadence rather than a feature one. The last four releases in the 3.8.2.x line are almost entirely gem updates, security backports and language file refreshes, with occasional small admin affordances like HTML in the maintenance banner or an env var to bypass host configuration. The one substantive batch in the window is 3.8.1's invitation flow work.

◆ Where it's heading

This is a stable, feature-complete front-end for BigBlueButton that its maintainers are keeping patched rather than growing. The patch-number depth (3.8.2.4) signals a team responding to CVE disclosures and dependency advisories on a schedule, not iterating on product. Where user-visible work does land, it clusters on administration: invitations, account provisioning, accessibility statements, RTL support.

◆ Prediction

Expect more 3.8.2.x patch releases dominated by gem updates and translations, with any real change confined to admin and onboarding surfaces.
