A side-by-side editorial comparison of Element Call and Fourwaves — release velocity, themes, recent moves, and the top alternatives to consider.
Legacy single-SFU mode is now gone, closing the multi-SFU migration it began in June.
Element Call has finished the call-topology migration it started two months ago. Multi-SFU became the default in v0.21.0 with legacy single-SFU negotiation still reachable from developer settings; this release deletes MatrixRTC legacy mode outright, so per-homeserver SFUs are the only topology left. The same release carries a substantial rendering performance pass — fewer context-menu re-renders, animations disabled at high tile counts, video fitted without polling RTP stats, redundant layout updates ignored — plus a configurable key-rotation participant limit.
Near-daily one-line releases, steadily removing friction from event setup and attendee use
Fourwaves ships an academic-conference platform and publishes a dated changelog entry almost every weekday, each carrying exactly one change in a single clean sentence. Titles are bare dates, so every headline has to be rewritten from the body. The current run mixes small UI repairs with real structural work on how event pages are addressed.

Two arcs are running together. The architectural one is nearly complete: transport discovery via .well-known went in the previous release, legacy RTC mode goes in this one, and the deprecation surface is shrinking release by release. The other is performance under load, which has been the recurring theme for three consecutive releases and points at large group calls as the case being optimised for. Every release in this window is an rc.1 that ships as the release, so the release-candidate labelling should not be read as instability.
With the legacy paths removed, expect the next releases to keep pushing on large-call rendering cost and on the embedded widget packages, which are versioned and published alongside every build.

Two threads are visible. Organiser-side work is tightening the event builder — guarding against deleting fields still in use, defaulting the program to a sensible date, cleaning up content-block layout. Attendee-side work is removing small indignities: muting microphones on join, letting visitors self-register from the sign-in page, fixing mobile messaging. Nothing here is directional; it is a team paying down friction one item at a time, which is why sparks are rare on this feed.
Expect the same one-change-per-day cadence to continue across both threads, with payment and registration plumbing the likeliest area for a larger item given the recent Authorize.net and checkout work.
