2.0.0-beta12 (July 12, 2019)

New Features

By default, you will subscribe to all RemoteTracks shared by other Participants in a Room. You can now override this behavior through a new ConnectOptions flag automaticSubscription. Setting it to false will make sure that you will not subscribe to any RemoteTrack in a Group or Small Group Room. Setting it to true, or not setting it at all preserves the default behavior. This flag does not have any effect in a Peer-to-Peer Room. (JSDK-2395)
```
  const { connect } = require('twilio-video');
  const room = await connect(token, {
    automaticSubscription: false
  });
```
twilio-video.js will now detect and attempt to recover from media disruptions quicker than before thereby improving the performance of the Network Reconnection API. (JSDK-2337)

Fixed a bug where Participants in a Group or Small Group Room stopped receiving Dominant Speaker and Network Quality updates when the media server recovered from a failover. (JSDK-2307)
Fixed a bug where, the local and remote AudioTracks' audioLevels returned by Room.getStats() were not in the range [0-32767]. (JSDK-2303)
Fixed a bug where Chrome and Safari Participants were enabling simulcast for H264 LocalVideoTracks when VP8 simulcast was enabled. (JSDK-2321)

On October 12, 2018, the specification for the JavaScript Session Establishment Protocol (JSEP) was updated to remove MediaStreamTrack IDs from Unified Plan SDPs (Media Session Descriptions). twilio-video.js depends on MediaStreamTrack IDs to map WebRTC MediaStreamTracks to the corresponding RemoteAudioTracks and RemoteVideoTracks. With this release of twilio-video.js, we have added support for the updated JSEP specification for Firefox and Safari (twilio-video.js uses Plan B SDPs on Chrome). We highly recommend that you upgrade to this version so your application continues to work on Firefox and Safari even after they support the updated JSEP specification. We will provide a detailed advisory once we have more information about when they are planning to support the updated JSEP specification. (JSDK-2385)
