LiveKit

Recently shipped a mock API server for testing server SDKs alongside egress v2 and Prometheus metrics in the server.

Server v1.13.x added a mock API server, egress v2, and Prometheus metrics. v1.13.3 shipped a mock API server for testing server SDKs with auth checks, plus average bitrate reporting for WHIP ingress. v1.13.2 added the egress v2 API, Prometheus join-latency and peer-connection-state metrics, subscription permission enforcement for data tracks, and async participant attributes via data blobs.

Rust SDK added a zero-playout-delay mode for native video subscribers. The local_video subscriber gained an opt-in --low-latency flag that isolates subscriber diagnostics from frame-driven rendering. Data-track logic was refactored into new shared crates (livekit-common, livekit-data-stream) and public fields were exposed on data-track types — public API is unchanged.

Python SDK added auto-failover APIs for LK Cloud. The client can now fail over between regions automatically. Frame processors also now fully configure when used directly on an audio stream.

Components and other SDK releases. Agents JS plugins for Hedra, xAI, Soniox, and Sarvam saw dependency-only patch bumps. The CLI reached v2.17.0 with SIP trunk media config support, agent deploy attributes, and JSON output on all commands.
