+- fixed several memory leaks (patch 3372909), contributed by Erik Kulyk)
+
+
 Version 0.6:
 - mostly reverted patch 2594366: alsapcm_setup did not do complete error 
 checking for good reasons; some ALSA functions in alsapcm_setup may fail without
 rendering the device unusable
 
+
 Version 0.5:
 - applied patch 2777035: Fixed setrec method in alsaaudio.c
   This included a mixertest with more features
