1.10.0 (May 30, 2018)

New Features

• A RemoteParticipant now maintains a collection of RemoteTrackPublications in a
  new .trackPublications property. It also maintains kind-specific
  RemoteTrackPublication collections (.audioTrackPublications,
  .dataTrackPublications and .videoTrackPublications). A "trackPublished"
  event is emitted on the RemoteParticipant (and subsequently on the Room) whenever
  a Track is published. A "trackUnpublished" event is emitted on the RemoteParticipant
  whenever a Track is unpublished. (JSDK-1438)

  participant.on('trackPublished', publication => {
    console.log('A new Track was published!', publication);
    assert.equal(participant.trackPublications.get(publication.trackSid), publication);
  });
  
  participant.on('trackUnpublished', publication => {
    console.log('A new Track was unpublished!', publication);
    assert(!participant.trackPublications.has(publication.trackSid));
  });

• Added trackSid to TrackStats, so now, when you call getStats on a Room,
  the TrackStats will include Track SIDs for local and remote Tracks.
  (JSDK-1716)

Bug Fixes

• Fixed a bug that cause remoteAudioTrackStats and remoteVideoTrackStats to
  always be empty Arrays in Firefox. (JSDK-1927)
• LogLevel was accidentally omitted from the API docs. (JSDK-1701)

RemoteTrackPublication Guide

A RemoteTrackPublication represents a Track that was published to the Room by
a RemoteParticipant.

publication.on('subscribed', track => {
  console.log('Subscribed to Track', track);
  assert.equal(publication.isSubscribed, true);
  assert.equal(publication.track, track);
});

publication.on('subscriptionFailed', error => {
  console.error('Subscription failed', error);
  assert.equal(publication.isSubscribed, false);
  assert.equal(publication.track, null);
});

publication.on('trackDisabled', () => {
  console.log('Track disabled');
  assert.equal(publication.isTrackEnabled, false);
});

publication.on('trackEnabled', () => {
  console.log('Track enabled');
  assert.equal(publication.isTrackEnabled, true);
});

publication.on('unsubscribed', track => {
  console.log('Unsubscribed from Track', track);
  assert.equal(publication.isSubscribed, false);
  assert.equal(publication.track, null);
});
