The latest is update Legendary Heroes which is in release, so no beta, download it from steam.
It still has problems with crashes and bugs, the AI is also pretty bad at playing the game and offers very little challenge. I don't think I've ever played through more than halfway through a game because it either starts crashing heavily or it suffers the same problem like many strategy games where you get to a point where you can just steam roll everything.
There are a lot of good things that it has going for it. Character customisation and progression is probably it's strongest feature as far as strategy games go. Balance and AI are it's weak links.
