We're pushing 3.2.6 back until next week. The AI development is something of a research project on its own, and the new pathfinding isn't up to par yet. The OpenGL shader support is working well on the Mac, but is still uncertain on Linux, and also needs to be tested on older Mac hardware before we can even have any certainty of basic functionality. Too many things are unfinished, slightly broken, or fundamentally untested for it to make sense for us to release in the short term.. even for a Test game. Some of the graphical changes we had planned for this release (damage effects and such) are also going well, but won't be up to snuff by tomorrow. Thus, we're going to delay it a little, spend some time making the AI a bit smarter and everything else a little more solid, and hopefully bring you a better build next week. Sorry to disappoint.
