0.13.0 (December 15, 2015)

New Features

twilio-conversations.js will now auto-stop any MediaStreamTracks it gathers
for you as part of inviteToConversation or accept-ing an IncomingInvite
when you disconnect from a Conversation. You can bypass this behavior by
passing in your own local MediaStream or LocalMedia object (JSDK-412)
The "participantFailed" event emitted by the Conversation is now
parameterized by a Participant object instead of merely the failed
Participant's identity.
Added the ability to remove a MediaStream from a LocalMedia object
Added the ability to specify whether or not to stop the LocalTrack when
removing it from a LocalMedia object (the default remains to stop the
LocalTrack)

Fixed a bug where detaching Media or a Track could raise an uncaught error
(JSDK-375)
Fixed a bug which made it impossible to add or remove LocalAudioTracks and
LocalVideoTracks and have it reflected to remote Participants (JSDK-411)
