        - `get_rtp_parameters_by_kind`.
    - `RTCRtpTransceiver`:
        - `sender`;
        - `set_sender`;
        - `receiver`.
    - `RTPReceiverInternal`:
        - `set_transceiver_codecs`;
        - `get_codecs`.
    - `RTCRtpSender`:
        - `set_rtp_transceiver`;
        - `has_sent`.
    - `TrackRemote`:
        - `id`;
        - `set_id`;
        - `stream_id`;
        - `set_stream_id`;

## v0.6.0

* Added more stats to `RemoteInboundRTPStats` and `RemoteOutboundRTPStats` [#282](https://github.com/webrtc-rs/webrtc/pull/282) by [@k0nserv](https://github.com/k0nserv).
* Don't register `video/rtx` codecs in `MediaEngine::register_default_codecs`. These weren't actually support and prevented RTX in the existing RTP stream from being used. Long term we should support RTX via this method, this is tracked in [#295](https://github.com/webrtc-rs/webrtc/issues/295). [#294 Remove video/rtx codecs](https://github.com/webrtc-rs/webrtc/pull/294) contributed by [k0nserv](https://github.com/k0nserv)
* Add IP filter to WebRTC `SettingEngine` [#306](https://github.com/webrtc-rs/webrtc/pull/306)
* Stop sequence numbers from increasing in `TrackLocalStaticSample` while the bound `RTCRtpSender` have
directions that should not send. [#316](https://github.com/webrtc-rs/webrtc/pull/316)
* Add support for a mime type "audio/telephone-event" (rfc4733) [#322](https://github.com/webrtc-rs/webrtc/pull/322)
* Fixed a panic that would sometimes happen when collecting stats. [#327](https://github.com/webrtc-rs/webrtc/pull/327) by [@k0nserv](https://github.com/k0nserv).
* Added new extension marshaller/unmarshaller for VideoOrientation, and made marshallers serializable via serde [#331](https://github.com/webrtc-rs/webrtc/pull/331) [#332](https://github.com/webrtc-rs/webrtc/pull/332)
* Updated minimum rust version to `1.60.0`
* Added a new `write_rtp_with_extensions` method to `TrackLocalStaticSample` and `TrackLocalStaticRTP`. [#336](https://github.com/webrtc-rs/webrtc/pull/336) by [@k0nserv](https://github.com/k0nserv).
* Added a new `sample_writer` helper to `TrackLocalStaticSample`. [#336](https://github.com/webrtc-rs/webrtc/pull/336) by [@k0nserv](https://github.com/k0nserv).
* Increased minimum versions for sub-dependencies:
  * `webrtc-data` version to `0.6.0`.
  * `webrtc-ice` version to `0.9.0`.
  * `webrtc-media` version to `0.5.0`.
  * `webrtc-sctp` version to `0.7.0`.
  * `webrtc-util` version to `0.7.0`.

### Breaking changes

* Allowed one single direction for extmap matching. [#321](https://github.com/webrtc-rs/webrtc/pull/321). API change for `MediaEngine::register_header_extension`.
* Removed support for Plan-B. All major implementations of WebRTC now support unified and continuing support for plan-b is an undue maintenance burden when unified can be used. See [“Unified Plan” Transition Guide (JavaScript)](https://docs.google.com/document/d/1-ZfikoUtoJa9k-GZG1daN0BU3IjIanQ_JSscHxQesvU/) for an overview of the changes required to migrate. [#320](https://github.com/webrtc-rs/webrtc/pull/320) by [@algesten](https://github.com/algesten).
* Removed 2nd argument from `RTCCertificate::from_pem` and guard it with `pem` feature [#333]
* Renamed `RTCCertificate::pem` to `serialize_pem`  and guard it with `pem` feature [#333]
* Removed `RTCCertificate::expires` [#333]
* `RTCCertificate::get_fingerprints` no longer returns `Result` [#333]
* Make functions non-async [#338](https://github.com/webrtc-rs/webrtc/pull/338):
    - `RTCDataChannel`:
        - `on_open`;
        - `on_close`;
        - `on_message`;
        - `on_error`.
    - `RTCDtlsTransport::on_state_change`;
    - `RTCIceCandidate::to_json`;
    - `RTCIceGatherer`:
        - `on_local_candidate`;
        - `on_state_change`;
        - `on_gathering_complete`.
    - `RTCIceTransport`:
        - `get_selected_candidate_pair`;
        - `on_selected_candidate_pair_change`;
        - `on_connection_state_change`.
    - `RTCPeerConnection`:
        - `on_signaling_state_change`;
        - `on_data_channel`;
        - `on_negotiation_needed`;
        - `on_ice_candidate`;
        - `on_ice_gathering_state_change`;
        - `on_track`;
        - `on_ice_connection_state_change`;
        - `on_peer_connection_state_change`.
    - `RTCSctpTransport`:
        - `on_error`;
        - `on_data_channel`;
        - `on_data_channel_opened`.

[#333]: https://github.com/webrtc-rs/webrtc/pull/333

## v0.5.1

* 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](https://github.com/webrtc-rs/webrtc/pull/290) contributed by [efer-ms](https://github.com/efer-ms)

## v0.5.0

### 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](https://github.com/webrtc-rs/webrtc/pull/153) contributed by [jmatss](https://github.com/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](https://github.com/webrtc-rs/webrtc/pull/154) contributed by [k0nserv](https://github.com/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](https://github.com/webrtc-rs/webrtc/pull/201) contributed by [k0nserv](https://github.com/k0nserv)
  * [#210 Rework transceiver direction support further](https://github.com/webrtc-rs/webrtc/pull/210) contributed by [k0nserv](https://github.com/k0nserv)
  * [#214 set_direction add missing Send + Sync bound](https://github.com/webrtc-rs/webrtc/pull/214) contributed by [algesten](https://github.com/algesten)
  * [#213 set_direction add missing Sync bound](https://github.com/webrtc-rs/webrtc/pull/213) contributed by [algesten](https://github.com/algesten)
  * [#212 Public RTCRtpTransceiver::set_direction](https://github.com/webrtc-rs/webrtc/pull/212) contributed by [algesten](https://github.com/algesten)
  * [#268 Fix current direction update when applying answer](https://github.com/webrtc-rs/webrtc/pull/268) contributed by [k0nserv](https://github.com/k0nserv)
  * [#236 Pause RTP writing if direction indicates it](https://github.com/webrtc-rs/webrtc/pull/236) contributed by [algesten](https://github.com/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](https://github.com/webrtc-rs/webrtc/pull/217) contributed by [k0nserv](https://github.com/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](https://github.com/webrtc-rs/webrtc/pull/237) contributed by [stuqdog](https://github.com/stuqdog)
  * [#229 Revert "base id updating on whether it's been negotiated, not on its …](https://github.com/webrtc-rs/webrtc/pull/229) contributed by [melekes](https://github.com/melekes)

  * [#226 base id updating on whether it's been finalized, not on its value](https://github.com/webrtc-rs/webrtc/pull/226) contributed by [stuqdog](https://github.com/stuqdog)

## Prior to 0.5.0

Before 0.5.0 there was no changelog, previous changes are sometimes, but not always, available in the [GitHub Releases](https://github.com/webrtc-rs/webrtc/releases).
