Version 0.6.1 of the Character Editor is now available here: http://apocalyptech.com/eschalon/
Windows users are strongly encouraged to upgrade, to avoid potential problems with locking the savegame directories, which could result in losing a savegame slot if you run the editor at the same time that Eschalon is running. Users on other platforms wouldn't be affected by this (it was a bug in the bundled version of gtk+ which was causing this).
Apart from that, there were a few minor bugfixes not really worth enumerating; check the ChangeLog for details if you want.
I believe 4-7 there are penalties for having things equipped you're not skilled with (weapon, light armor, heavy armor, and shield in that order)
FYI, I ended up taking out the "permanent" statuses which are automatically computed by the game engine. When I added in the weapon penalties, it just seemed like too much wasted space for values which you can't actually
change in the game (since your changes would just get overwritten as soon as the game is loaded). So those aren't present in the GUI anymore (they'd still show up when listing characters from the CLI, though).
