LJGF 0.0.5 was released to the wild, adding fun bag of new features, such as
0.0.5 breaks backwards compatibility, though, as lots of classes were moved into different namespaces or renamed to match the new additions. A small disadvantage is, that the MP3 sound engine relies upon JLayer, which is LGPL software (despite the licensing, it is an excellent package for working with MP3 encoded audio data). This however does not have any impact on the rest of the sofware, which is still Public Domain.
Enjoy!
