 - **WASAPI**: Default device changes no longer report `DeviceChanged`, which wrongly implied the stream had rerouted automatically.
 - **WASAPI**: Reported buffer sizes are no longer off by one frame.
 - **WASAPI**: `Stream::drop`, `play`, and `pause` no longer panic when the device is lost.
+- **WASAPI**: Output streams no longer reject formats that the built-in resampler can convert.
 - **WebAudio**: Fix stale audio output when a data callback wrote a partial buffer.
 - **WebAudio**: Fix unsound `Send + Sync` on `Stream` when compiled with `+atomics`.
 - **WebAudio**: Fix `Host::is_available()` always returning `true`, even in non-window contexts.
