It's patch day for Diablo III, and the massive 1.0.4 update is scheduled to deploy during this morning's downtime. Update 1.0.4 adds a number of new changes to all of Diablo III's classes, improvements to Legendary Item to make them more unique and desirable, the new 100 level Paragon system, better auction house functionality and more.
A very long list of patch notes for the update is available on the Diablo III forums.
