 v0.10.22 - TBD
   - Refactor to the PulseAudio backend.
   - Fix bugs in ma_decoder_init_file*() where the file handle is not closed after a decoding error.
+  - ALSA: Fix a bug in ma_context_get_device_info() where the PCM handle is left open in the event of an error.
 
 v0.10.21 - 2020-10-30
   - Add ma_is_backend_enabled() and ma_get_enabled_backends() for retrieving enabled backends at run-time.
