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)
