    • Shape -> StreamConfig - The configuration input required to build a stream.
    • Format -> SupportedStreamConfig - Describes a single supported stream configuration.
    • SupportedFormat -> SupportedStreamConfigRange - Describes a range of supported configurations.
    • Device::default_input/output_format -> Device::default_input/output_config.
    • Device::supported_input/output_formats -> Device::supported_input/output_configs.
    • Device::SupportedInput/OutputFormats -> Device::SupportedInput/OutputConfigs.
    • SupportedFormatsError -> SupportedStreamConfigsError
    • DefaultFormatError -> DefaultStreamConfigError
    • BuildStreamError::FormatNotSupported -> BuildStreamError::StreamConfigNotSupported
  • Address deprecated use of mem::uninitialized in WASAPI.
  • Removed UnknownTypeBuffer in favour of specifying sample type.
  • Added build_input/output_stream_raw methods allowing for dynamically handling sample format type.

Version 0.11.0 (2019-12-11)

  • Fix some underruns that could occur in ALSA.
  • Add name to HostId.
  • Use snd_pcm_hw_params_set_buffer_time_near rather than set_buffer_time_max in ALSA backend.
  • Remove many uses of std::mem::uninitialized.
  • Fix WASAPI capture logic.
  • Panic on stream ID overflow rather than returning an error.
  • Use ringbuffer crate in feedback example.
  • Move errors into a separate module.

  • Allow users to handle stream callback errors with a new StreamEvent type.
  • Overhaul error handling throughout the crate.
  • Remove unnecessary Mutex from ALSA and WASAPI backends in favour of channels.

  • Add input stream support to coreaudio, alsa and windows backends.
  • Introduce StreamData type for handling either input or output streams in EventLoop::run callback.
  • Add Device::supported_{input/output}_formats methods.
  • Add Device::default_{input/output}_format methods.
  • Add default_{input/output}_device functions.
  • Replace usage of Voice with Stream throughout the crate.
  • Remove Endpoint in favour of Device for supporting both input and output streams.

Version 0.7.0 (2018-02-04)

  • Rename ChannelsCount to ChannelCount.
  • Rename SamplesRate to SampleRate.
  • Rename the min_samples_rate field of SupportedFormat to min_sample_rate

  • Remove unused ChannelPosition API.
  • Implement Endpoint and Format Enumeration for macos.
  • Implement format handling for macos build_voice method.

Version 0.6.0 (2017-12-11)

  • Changed the emscripten backend to consume less CPU.
  • Added improvements to the crate documentation.
  • Implement pause and play for ALSA backend.
  • Reduced the number of allocations in the CoreAudio backend.
  • Fixes for macos build (#186, #189).

Version 0.5.1 (2017-10-21)

  • Added Sample::to_i16(), Sample::to_u16() and Sample::from.

Version 0.5.0 (2017-10-21)

  • Removed the dependency on the futures library.
  • Removed the Voice and SamplesStream types.
  • Added EventLoop::build_voice, EventLoop::destroy_voice, EventLoop::play, and EventLoop::pause that can be used to create, destroy, play and pause voices.
  • Added a VoiceId struct that is now used to identify a voice owned by an EventLoop.
  • Changed EventLoop::run() to take a callback that is called whenever a voice requires sound data.
  • Changed supported_formats() to produce a list of SupportedFormat instead of Format. A SupportedFormat must then be turned into a Format in order to build a voice.
