Automattic has released Wordpress 2.8.0 an open source (GPL) blog engine based on PHP and MySQL. "2.8 represents a nice fit and finish release for WordPress with improvements to themes, widgets, taxonomies, and overall speed. We also fixed over 790 bugs." And here I just finished upgradinbg to 2.7.1. None of the new features seem especially compelling to me, so I'll probably just stay there for a while.
