Full Changelog: v0.17.1...v0.17.2

• Fix over-NACK due not resetting lost_packets bitmask #372.
• Increased minimum support rust version to 1.60.0.
• Increased required webrtc-util version to 0.7.0.

• #14 Prevent crash in RTCP NACK writing by @pthatcher.
• Adds IntoIterator for NackPair which iterates over all the sequence numbers specified by the NackPair. This is similar to packet_list but without requiring the allocation of a Vec. Added in #225 Add RTP Stats to stats report by @k0nserv.

• Promote agent lock in ice_gather.rs create_agent() to top level of the function to avoid a race condition. #290 Promote create_agent lock to top of function, to avoid race condition contributed by efer-ms

Changes

Breaking changes

• The serialized format for RTCIceCandidateInit has changed to match what the specification i.e. keys are camelCase. #153 Make RTCIceCandidateInit conform to WebRTC spec contributed by jmatss.
• Improved robustness when proposing RTP extension IDs and handling of collisions in these. This change is only breaking if you have assumed anything about the nature of these extension IDs. #154 Fix RTP extension id collision contributed by k0nserv
• Transceivers will now not stop when either or both directions are disabled. That is, applying and SDP with a=inactive will not stop the transceiver, instead attached senders and receivers will pause. A transceiver can be resurrected by setting direction back to e.g. a=sendrecv. The desired direction can be controlled with the newly introduced public method set_direction on RTCRtpTransceiver.
  • #201 Handle inactive transceivers more correctly contributed by k0nserv
  • #210 Rework transceiver direction support further contributed by k0nserv
  • #214 set_direction add missing Send + Sync bound contributed by algesten
  • #213 set_direction add missing Sync bound contributed by algesten
  • #212 Public RTCRtpTransceiver::set_direction contributed by algesten
  • #268 Fix current direction update when applying answer contributed by k0nserv
  • #236 Pause RTP writing if direction indicates it contributed by algesten
• Generated the a=msid line for m= line sections according to the specification. This might be break remote peers that relied on the previous, incorrect, behaviour. This also fixes a bug where an endless negotiation loop could happen. #217 Correct msid handling for RtpSender contributed by k0nserv
• Improve data channel id negotiation. We've slightly adjust the public interface for creating pre-negotiated data channels. Instead of a separate negotiated: Option<bool> and id: Option<u16> in RTCDataChannelInit there's now a more idiomatic negotiated: Option<u16>. If you have a pre-negotiated data channel simply set negotiated: Some(id) when creating the data channel.

  • #237 Fix datachannel id setting for 0.5.0 release contributed by stuqdog

  • #229 Revert "base id updating on whether it's been negotiated, not on its … contributed by melekes

  • #226 base id updating on whether it's been finalized, not on its value contributed by stuqdog
