- changes from version 0.8.1:
  * document changes (this file)
- changes from version 0.8:
  * 'PCM()' has new 'device' and 'cardindex' keyword arguments.
    + The keyword 'device' allows to select virtual devices,
    'cardindex' can be used to select hardware cards by index (as
    with 'mixers()' and 'Mixer()').
    + The 'card' keyword argument is still supported, but deprecated.
    + The reason for this change is that the 'card' keyword argument
    guessed a device name from the card name, but this only works
    sometimes, and breaks opening virtual devices.
  * new function 'pcms()' to list available PCM devices.
  * mixers() and Mixer() take an additional 'device' keyword argument.
    This allows to list or open virtual devices.
  * The default behaviour of Mixer() without any arguments has
    changed.  Now Mixer() will try to open the 'default' Mixer instead
    of the Mixer that is associated with card 0.
  * fix a memory leak under Python 3.x
  * some more memory leaks in error conditions fixed.
