+## [0.21.0] - 2023-08-08
+### Changed
+- Minimum supported Rust version is updated to 1.70.0.
+- Compatible with gtk-rs-core 0.18.
+- `gst::Bin::add_many()`, `remove_many()` and `gst::Element::link_many()`,
+  `unlink_many()` are more generic now.
+- `gst_base::Aggregator::src_pad()` returns an `AggregatorPad`.
+- `gst::Bus::add_watch()` now returns a guard value that automatically removes
+  the watch when it goes out of scope.
+- `gst::Bin`, `Pipeline` and `Pad` constructors don't take the optional name
+  parameter anymore but it can instead be provided via the builder API.
+- `gst::Pad` and `GhostPad` builders inherit name from the pad template (or
+  target) if possible and no other name is provided explicitly.
+- The preroll samples and selected sticky events are forwarded to `StreamProducer` consumers.
+
+### Added
+- Support for the upcoming GStreamer 1.24 APIs.
+- Support for inline variable names in format strings for error/warning/info
+  messages.
+- Methods for converting between floating point seconds and `gst::ClockTime`.
+- Various additions to the gst-validate bindings.
+- `Display` implementations for error/warning/info messages.
+- More useful `Debug` implementations for messages, events and queries and
+  `gst_pbutils::DiscovererInfo` related structs.
+- API for listing/checking `gst::Meta` tags.
