0.13.4 (February 4, 2016)

Bug Fixes

• Fixed a regression in removeTrack and related methods which caused the
  "trackRemoved" event not to be propagated to remote Participants (JSDK-512)
• Fixed a bug where getUserMedia would be called multiple times when accepting
  an IncomingInvite without a LocalMedia object; in Firefox, this could result
  in failing to join a Conversation; now, getUserMedia will be called at
  most once (JSDK-439)
• Removed a postinstall script that caused failures with NPM 3.
• Fixed a bug where a LocalTrack removed with removeTrack could not be added
  back with addTrack (JSDK-548)
• Fixed a bug where calling stop on a LocalTrack caused it to be removed
  (JSDK-549)
