Enhanced

• Video playback in Safari and Firefox by removing black bars from 4:3 aspect ratio.

• Maximum number of participants per canvas to 25 (5×5), increased from 9 (3×3) previously supported.

• Video statistics and data to include FPS and resolution of each rendered video.

  • Enabled using the subscribeVideoStatisticDatamethod, with data acquired using the video-detailed-data-change event.

• Starting video in mobile browsers with front-facing camera mode support.

• Video quality support (up to 720p) for Intel Macs.

• Command channel by reducing delay between messages.

Fixed

1. An issue where if the host unmutes someone with unmuteAudio, the user receives the host-ask-unmute-audio event instead of the audio being unmuted directly.

2. Edge cases on Firefox where calling startAudio would always return an unresolved promise.
