v1.4.0 (2015-05-19)

• Update to not use deprecated Mopidy audio APIs.

• Use strings and not ints for the model's date field. This is required for
  compatibility with the model validation added in Mopidy 1.1. (Fixes: #52)

• Fix error causing the image of every 50th URI in a library.get_images()
  call to not be looked up and returned.

• Fix handling of empty search queries. This was still using the removed
  playlists.playlists to fetch all your tracks.

• Update the SpotifyTrack proxy model to work with Mopidy 1.1 model
  changes.

• Updated to work with the renaming of mopidy.utils to mopidy.internal
  in Mopidy 1.1.
