One of the hotfixes released today addresses an exploit used to circumvent the recent decreases in attack speed. Before the hotfix, players could "temporarily increase their attack speed or double-cast a skill" by repeatedly clicking the Town Portal option within the hot bar. A complete list of fixes can be found on the official game blog.
In changes made yesterday, Blizzard once again increased high-level item drops in Acts III and IV of Hell difficulty and all four acts in Inferno. The breakdown of increases can be found after the break. Not found after the break: those hundred hours you've spent clicking through Sanctuary.
