	Removed `channel` and `direction` from `clockSourceDidChange(audioDevice:)` signature in `AudioDeviceEvent` protocol.
3.1.1	Fixed broken `setDefaultDevice(_:)` functionality (reported by @DerButtsche.)	March 13th, 2017
3.1	Deprecated the `AM` prefix in all classes/enums/structs and modernized many function signatures. Old names and signatures are marked for removal in 3.2.	December 21st, 2016
	Added `isJackConnectedDidChange(audioDevice:)` notification.
	Added `preferredChannelsForStereoDidChange(audioDevice)` notification.
	Added some LFE (Low Frequency Effects) functions and variables.
	Added `setPreferredChannelsForStereo(channels:direction:)`.
	Changed `nominalSampleRate()` and `actualSampleRate()` implementations so they return nil in the event 0 is returned by Core Audio.
	Improved `volumeInfo(channel:direction:)` implementation so it does not return a `VolumeInfo` struct unless it is actually populated with any valid values.
	Removed the need to manually enable and disable device monitoring in `AudioHardware`.
	Added `TerminalType` and `StereoPair` enums.
	Changed all enum values to camelCase to follow Swift 3 conventions.
	Removed `.invalid` direction (it was only used internally and is no longer required.)

3.0.1	Added `AMCoreAudio` `setHogMode()` and removed `setHogModePidToCurrentProcess()` and `setHogModePID(_:)`	October 30th, 2016
	Fixed `unsetHogMode()` so it does not actually try to request hog mode instead of unsetting it when hog mode is not set.
	Changed `AMCoreAudio` `channelsForDirection(_:)` to calculate the total channel count based on the sum of channels in every stream's physical format. Old implementation is still available as `layoutChannelsForDirection(_:)`
3.0	Added Swift 3 support and new Pub/Sub notification system.	October 5th, 2016

2.0.2	Fixed that `AMCoreAudio.allOutputDevices()` was not declared as a public method.	July 13th, 2015
2.0.1	`preferredStereoChannelsForDirection(Direction)` now returns an optional `UInt32` array.	July 12th, 2015
	Misc improvements in documentation.
2.0	First Swift-only release.	July 12th, 2015
	Added `deviceManufacturer()`, `deviceIsHidden()`, `transportType()`, `ownedObjectIDs()`, `controlList()`, `relatedDevices()`, `classID()` to `AMCoreAudioDevice`.
	Changed `channelsForDirection(Direction)` so it is based on `kAudioDevicePropertyPreferredChannelLayout`.
	Audio device and audio hardware notifications now run on their own GCD queues.
	`AMCoreAudioDirection` is now `Direction`. `AMCoreAudioVolumeInfo` is now `VolumeInfo`.
	Many functions DO return optionals now.
