Version 0.0.2. This version has increased functionality. Well almost. It has 2 new buttons for playing and rewinding. Yes it is true that the don't work but atleast they are there.
mp3GTK version 0.01 released. This is a VERY simplistic version that only has the capabilaties to play 1 file at a time and that file has to be specified in the source code before compilation. It is soley meant for developers and to get the bugs out of the playing process.
