The RTCDataChannelInit.maxRetransmitTime dictionary member is being renamed to maxPacketLifeTime. This member is used to construct an unreliable data channel, which will stop attempting to retransmit a message after "maxPacketLifeTime" milliseconds. An unreliable data channel may be used to, for example, send non-critical information to a user about the reason for a state update in a video chat or conference.
