Open source TURN and STUN server for WebRTC and VoIP NAT traversal

github.com/coturn/coturn ↗

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.
