File Format Spec 3.0 released

The third version of the file format specification has been released. Without breaking backwards compatibility, it has been simplified a lot. One important field has been removed though: The Group field in the [Global] section. This information has basically been moved to the cpdir.txt file, and if anybody finds that this is causing trouble, don't hesitate to contact me, and I will write a tool that converts from the old 2.0 version to this new version.
