Hello all, Sage 4.3.alpha0 is out! Sage 4.3 now contains much of the new categories code from the sage-combinat team! It's been in development for quite awhile, and it's great to finally get it in. There is one known failure in sage/interfaces/maxima.py caused by #7401. This issue will be fixed in alpha1 when it comes out.
