I've upgraded Drupal to 5.12. I plan to upgrade to 6 in the near future.
Going to version 6 will require some significant changes: The module I'm using to handle item imports from the armory is not being maintained. While this shouldn't require having to redo some entries, I will have to rewrite this module myself. Either I will replace it with a lengthy, behind-the-scenes import from the Armory like the current module or I will implement it on top of itemstats. Either way, it's going to be interesting.
3.0.x has also seen me seriously picking up addon development and I want to get proper pages set up here for that too. It's just a matter of time...
