New creatures have been released:
Blink dog, Chimera, Chaos Beast, Centaur, Goblin, Gnome, Gnoll, Troll, Roper, Clay Golem, Iron Golem, Owlbear, and all ages green dragons and the red dragon great wyrm.
Also skills now are displayed and auto-assigned using a fairly intuitive strategy that tends to try to max out class skills and emphasizes a few specific skills based on creature type, or character class. Your Bugbear shouldn't usually get assigned 3 different perform skills unless he has bard levels.
Feats are now properly calculated including class levels. (Does not yet include bonus feats--although monk bonus feats are set up to assign randomly already)
There is a place on the display screen that now shows how many stat points the creature should have gained from advancement. (Just as a side note...if you ever actually do the math on the creatures you will realize that most monsters in the books ignore the whole extra stat point every 4 levels completely so I tend to not worry about it...keep in mind that in the main application that the table that shows the stats can be clicked on and every stat can be edited manually so the stats are always up to you.)
Also the main application now opens a new window for each creature you advance so that the javascript heavy page doesn't have to keep reloading.
Fixed a few problems with the printing from the stat block page. If you print the it should display only the things you would want displayed on your stat block automatically. (You don't have to cut and paste to another program if you don't want to)
