The next version of Exaile, which was to be version 0.3.3, will be version 3.3.0. We feel that the 0.x versioning was more confusing than actually useful or representative of the development process; in addition, the new versioning avoids long version numbers like 0.3.2.1.
In related news, Exaile 3.3.0 is going to be released soon. The RC is already out; please help us test it and iron out last-minute bugs.
