LiveKit Server

A mock API server for testing server SDKs is now available with auth check support. Fixed a WHIP session notifier that was not stopping when participants leave, and updated webrtc to fix an interop issue with bundled datachannel.

Added support for data blobs (async participant attributes) and an egress v2 API. Also caps all metadata at 512 KiB, adds Prometheus metrics for join latency and peer connection state, and enforces subscription permission to data tracks.

Backwards compatibility for TURN authentication without TTL has been removed; refer to v1.12.0 changelog for migration details. Also added per-data-track bytes reporting, participant kind codes, metrics for active participants, and TURN secret configuration via file.

TURN will no longer relay traffic to private IPs by default; use allow_restricted_peer_cidrs to permit specific CIDRs. TURN credentials now have a configurable TTL (defaults to 300 seconds) beyond which they cannot be used to join a room. Backwards compatibility is maintained in this release but will be removed in the next release. Also added client capabilities support, SIP auth realm for inbound, and auto room creation for tokens with RoomCreate grant.

NOTE: Minor version bump that enables data tracks (https://docs.livekit.io/transport/data/data-tracks/) by default.
