- Demote Recommends to Suggests.

- Update to version 2.0.4
  * Removed smpeg support for mp3 music, now that it's replaced
    by libmpg123.
  * Fixed mp3 mad decoder to skip tags, which otherwise would lead
    to crashes.
  * Added support for Opus music playback using opusfile library.
- Update to version 2.0.3
  * Fixed regression where Mix_Init() would return 0 for available
    music formats.
- Remove patch:
  * SDL2_mixer-only-load-required-interfaces.patch (fixed by upstream)

- update to version 2.0.2
  * 24-bit and surround sound support for FLAC audio files
  * Updated for SDL 2.0.6 and newer
  * Support for MP3 playback using mpg123
  * Added Mix_OpenAudioDevice() to specify the audio device to open
- Add SDL2_mixer-only-load-required-interfaces.patch
  Prevents initializing decoders unnecessarily.

  (due to misleading documentation).

  (they are already available through SDL(1)_mixer)

- Some metadata spruce-up: add current URLs, softer wildcarding
  in the files list
