+## [0.20.7] - 2023-07-05
+### Fixed
+- Fix `wait-for-eos` property name string in `appsink`.
+- Fix various memory leaks in `BaseTransform` subclassing bindings.
+- Mark some GES APIs as `Send+Sync`.
+
+### Added
+- Implement `DiscovererInfo::debug()` and on related structs.
++ Add subclassing bindings for `GESFormatter`.
+
+## [0.20.6] - 2023-06-06
+### Added
+- Getter for the `gst_rtsp_server::RTSPContext` URI field.
+
+### Fixed
+- `gst_pbutils::DiscovererStreamInfo::stream_id()` can return `NULL`. This is
+  mapped to the empty string for this release to keep backwards compatibility.
+- `gst_pbutils::DiscovererStreamInfo` iterator methods can be called on any
+  subclass directly now without casting.
+- Debug logs use the actual function name against instead of the name of a
+  closure generated by the log macros.
+
+### Changed
+- Minor performance improvements to debug logging.
+
+## [0.20.5] - 2023-04-22
+### Added
+- `glib::HasParamSpec` impl for miniobjects to allow using them with the
+  properties derive macro.
+- `Default` impl for `gst_player::Player`.
+
+## [0.20.4] - 2023-04-07
+### Fixed
+- Work around `gst_webrtc::WebRTCICE::add_candidate()` API breakage in 1.24.
+
+### Changed
+- Reduce size of `gst_audio::AudioBuffer` and `gst_video::VideoFrame` by a
+  factor of two by not storing an unnecessary copy of the audio/video info.
+
+## [0.20.3] - 2023-03-14
+### Fixed
+- `gst::ParamSpecArray` uses the correct `glib::Type` now.
+- Work around accidental ABI breakage in 1.18 gst-rtsp-server `GstRTSPClient`.
+
+### Added
+- Document `gst_utils::StreamProducer::forward_eos()` default value.
+
+## [0.20.2] - 2023-02-21
+### Added
+- `glib::HasParamSpec` impl for `gst::ClockTime`
+- `Default` impl for `gst_play::Play`
+- Constructors for non-raw `gst_audio::AudioCapsBuilder` / `gst_video::VideoCapsBuilder`
+
+## [0.20.1] - 2023-02-13
+### Fixed
+- Fix memory leaks when converting a `gst_audio::AudioBuffer` or
+  `gst_video::VideoFrame` to a `gst::Buffer` or FFI type.
+
 ## [0.20.0] - 2023-02-10
 ### Fixed
 - Make `gst_gL::GLDisplay::create_context()` `other_context` parameter optional.
