jluerken,
As I stated 6.3 has alot of bugfixes and a few MOD additions. It is still beta so who knows if Rick is gonna sneak something new in.
He used 6.3 as a CLEAN UP CODE version. He templated the language files as well as the admin area. He added area in admin section to add language files on the fly. Alot of behind the door stuff. Most things are templated now which makes it tons easier to edit them.
6.4 I know has the calendar slated for it. I do not know about sub-forums but that would be cool.
