What's New

Newer tag v1.13.3 is numerically older than v1.16.1 and swaps jailer/vsock fixes for WebRTC and mock-server features

Breaking Changes

  • The version number regresses from 1.16.1 to 1.13.3, so adopting this release is effectively a downgrade that drops the jailer symlink revert and the vsock snapshot-restore fix.
  • The DataBlobKey log name is now camel case, which can break log parsers, alerts, or dashboards keyed on the previous field name.
  • The bundled webrtc dependency update changes data channel interop behavior, so clients validated against the prior bundling should be re-tested.

New Features

  • A mock API server is included for testing server SDKs without a live backend.
  • The mock server supports auth checks, enabling end-to-end authentication testing.
  • Data track schema metadata is now exposed.
  • Average bitrates are reported for WHIP ingress.

Improvements

  • The webrtc library was updated to resolve interop issues with bundled data channels.
  • The github.com/urfave/cli/v3 dependency was bumped to v3.10.0.
  • Log naming for DataBlobKey was normalized to camel case for consistency.

Bug Fixes

  • The WHIP session notifier is now stopped when a participant leaves, preventing a lingering notifier.

Upgrade Notes

Treat this as a downgrade rather than an upgrade: the tag is lower than v1.16.1 and the jailer symlink and vsock snapshot-restore fixes present in the older release are absent here. If you depend on the DataBlobKey log field, update parsers for the new camel case name before rolling out. Re-run WebRTC/data channel integration tests after the bundled library change.
