coturn
2.5MEETINGS
coturn ships three minor versions in six weeks, packaged as Docker images on three registries.
◆ Current state
The tracked feed for coturn, the open-source TURN/STUN server, is Docker image releases: 4.16.0, 4.17.0, 4.17.1, 4.17.2 and 4.18.0 between late July and early September 2026. Each is published to Docker Hub, GitHub Container Registry and Quay.io, and the release notes here point to the upstream changelog without listing changes.
◆ Where it's heading
The cadence picked up: three minor versions (4.16, 4.17, 4.18) landed in about six weeks, with two same-day patch images for 4.17. The project keeps container packaging in lockstep with upstream releases, which matters to operators running TURN for WebRTC in containers.
◆ Prediction
A 4.18.x patch image or a 4.19.0 release is the likely next entry, following the observed roughly two-to-four-week rhythm; the feature content is not visible from these entries.
Fourwaves
6.3MEETINGS
Fourwaves is polishing participant messaging after a pricing reset.
◆ Current state
Fourwaves ships small daily changes to its event and conference platform. The past two weeks focused on participant communication — direct-message alerts, richer discussion emails, a communication Preferences page — plus account-page and domain-settings cleanup.
◆ Where it's heading
The September 17 pricing change to yearly submission limits with unlimited events set the commercial frame; the product work since then makes ongoing participant engagement smoother. Direct messages are replacing older contact paths.
◆ Prediction
More notification and messaging controls for participants and organizers are likely, continuing the current run of small communication fixes.
