+PipeWire 0.3.21
+
+This is a bugfix release that is API and ABI compatible
+with previous 0.3.x releases.
+
+- Highlights
+  - Many PulseAudio compatibility fixes. Handling of corked
+    streams, the prebuf setting, seek modes and stream flags
+    are now implemented correctly.
+  - Ports and Profiles are now managed by the session manager
+    and can save and restore previous settings.
+  - ALSA device handling has been tweaked for maximum
+    compatibility at the expense of latency. There are tuning
+    options in the config file.
+  - Improved Bluetooth support. HSP is disabled by default
+    because it is old and deprecated and in some cases causes
+    conflicts with the newer HFP profile. Codec switching is
+    now implemented as well.
+  - PipeWire accepts donations with liberapay now.
+
+- PipeWire improvements
+  - Improve draining in pw-stream.
+  - pw-stream now uses busy metadata by default. This makes sure
+    that no writer can write to buffers when readers are still
+    busy.
+  - Fix handling of empty array/choice instead of failing.
+  - Fix crashes when creating properties from empty strings.
+  - Make it possible to pass an array to module-access
+    access.allowed variables
+  - Fix small bug in argument parsing in pw-cat
+
+- Session-manager
+  - Restore route volumes in all cases, also when switching
+    routes.
+  - Use a default route volume for unknown routes instead of
+    letting the system decide on a default.
+  - Improve profile handling. Don't try to restore unavailable
+    profiles. Implement the profile switching in the session
+    manager now.
+  - Fix handling of Virtual sources as defaults.
+  - Handle port switching in the session manager. Implement
+    save and restore of default ports per profile.
+
+- GStreamer
+  - Fix a crash with zero SPA_PARAM_BUFFERS_size
+
+- Device support
+  - v4l2-source will now respect the requested memory types.
+  - ALSA buffering has been tweaked. USB devices should have
+    less XRuns by default. Parameters can be tweaked to
+    decrease the latency on capable devices. Also fix a case
+    where a quantum change would cause an xrun.
+  - Fix mute in bluetooth devices
+  - bluetooth devices are not paused in idle anymore for
+    improved compatibility.
+  - Codec switching for bluetooth is implemented along with
+    config options to select the codecs manually.
+  - HSP for bluetooth is now disabled by default. Most devices
+    support the newer HFP profile and some devices fail when
+    both are available.
+  - Reduce the amount of events the ALSA plugins emit by bundling
+    them.
+
+- PulseAudio server
+  - Implement the suspend command
+  - Fixes volume in sample info
+  - Fix playback of samples, sometimes samples would be clipped
+    short. Also implement the target sink for the sample.
+  - Use rate match to feed samples. This way the latency can
+    be kept to a minimum.
+  - Latency has been tuned some more, more closely emulating
+    pulseaudio behaviour.
+  - Improve default sink/source handling. Make sure all events
+    are sent correctly when defaults change.
+  - Handle underrun better without causing sync issues. Make sure
+    to pause in corked state.
+  - Implement rewind due to seeks, fixes GStreamer seeking.
