1.0.0-beta7 (April 21, 2017)

Bug Fixes

• The first known issue in 1.0.0-beta6 stems from a behavior in Chrome: Chrome
  will treat an SSRC change for a MediaStreamTrack as adding and removing the
  MediaStreamTrack; this caused a problem in our SDK, as the first
  MediaStreamTrack would be raised to the user wrapped in a Track object, but
  would eventually become unusable due to the SSRC change. We workaround this
  behavior by "fixing" the SSRCs announced in an SDP between calls to
  createOffer. Firefox does not exhibit this behavior. (CSDK-1206)
• Calling addTrack, removeTrack, or their plural variants in the same tick
  could lead to sending more messages than necessary; we landed an optimization
  to reduce these additional messages. (JSDK-1257)
