1.6.0 (October 24, 2017)

New Features

Added DataTrack support in Group Rooms. Previously, DataTracks only worked in
Peer-to-peer Rooms. Now they work in both. Consequently, the "experimental"
warning has been removed.
Added LocalDataTrackOptions. These options allow you to configure the
maxPacketLifeTime, maxRetransmits, and ordered properties of a
LocalDataTrack's underlying RTCDataChannel(s).
Added "trackPublicationFailed" and "trackPublished" events to the
LocalParticipant. Previously, if you failed to publish a LocalTrack when
connecting to a Room, there was no API to discover what went wrong. Now, if
you fail to publish a LocalTrack at connect-time—for example, due to a codec
mismatch or an invalid Track name—we will raise a "trackPublicationFailed" on
the LocalParticipant with an informative error. Similarly, if publication
succeeds, we will raise a "trackPublished" event with the resulting
LocalTrackPublication.
Added a new top-level boolean property, isSupported, that indicates whether
or not the browser/environment/platform currently running twilio-video.js
contains the necessary APIs (for example, WebRTC) to participate in video
chats. Depending on how you use twilio-video.js, you can use one of the
methods below to access it:
```
// Option 1: Using `require`
const { isSupported } = require('twilio-video');

// Option 2: Using browser global
const { isSupported } = Twilio.Video;
```
