+Version 0.8.1:
+- document changes (this file)
+
+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
+
