;;;; -*- coding: utf-8; fill-column: 78 -*-

changes relative to Benben 0.5.0:
  * New: Quite OK Audio (QOA) format support added.
  * Enhancement: You can now specify either a single theme, or an array of
    themes, in the config file.  When it's an array, a random one out of that
    array will be chosen.
  * Enhancement: If the terminal is larger than 80x24, the play queue will
    expand to fill the empty space (it previously expanded horizontally, but
    not vertically).
  * Enhancement: Normalization now happens in parallel as jobs are being

* SoundFonts: Mostly working (the "global" soundfont is technically set
  incorrecly - see TODO in code)
* MP1/2/3: working
* FLAC: working
* Opus: Working
* Vorbis: working
* WAV/Au: working
* QOA: working
* XSPF/JSPF: working, seems to use more RAM than I would like
* Local files: working
* HTTP: removed
* Gemini: removed

=============
