Looks like we are getting a bug fix release in a matter of days. There was quite a nasty bug.
Crucial bug fix done: doing an Undo with pointcaches (simulations like smoke, fluids) crashed Blender.
It is so nice to know that our coders respond so quickly to our concerns. Not all softwares come with such amazing support, so hug the nearest coder you can find and give them a big thanks.
