* Added model `RepeatSettingTypes` - repeat setting types enumeration.
* Added model `ShuffleSettingTypes` - shuffle setting types enumeration.

* Added method `SoundTouchClient`.`MediaSeekToTime` - Start playing the current media at the specified position in seconds (e.g. seek to time) if the currently playing media supports it.

* Adjusted the maxsize value of the PoolManager constructor. This WILL fix the "Connection pool is full, discarding connection ..." messages for environments with a large number of SoundTouch devices. The attempts prior to this fix were adjusting the wrong parameter (num_pools instead of maxsize).
* Added SourceTitle property to the `NavigateResponse` class. This returns a user-friendly source title for the `SoundTouchClient`.`GetMusicServiceStations` and `GetMusicLibraryItems` methods.

* Increased number of connection pools in PoolManager constructor from 30 to 75. This should fix the "Connection pool is full, discarding connection ..." messages for environments with a large number of SoundTouch devices.

* Added method `SoundTouchClient`.`ToggleZoneMember` - Toggles the given zone member in the master device's zone. If the member exists in the zone then it is removed; if the member does not exist in the zone, then it is added. A new zone is automatically created if necessary.

* Added `resolveSourceTitles:bool` argument to `SoundTouchClient`.`GetPresetList` and `GetRecentList` methods, so that a friendly source title can be displayed in user-interfaces.
* Added `Preset`.`SourceTitle` property - contains a friendly source title that can be displayed in user-interfaces.
* Added `Recent`.`SourceTitle` property - contains a friendly source title that can be displayed in user-interfaces.
