Following the auto-update early this week, there are now manual patches for Warcraft III: Reign of Chaos, bringing the English and European editions of Blizzard's 3D real-time strategy game to version 1.04b. This patch was uploaded to Blizzard's FTP server less than an hour after 1.04a. I'll let you decide which patch you want to install, there are no noted changes on the official site.
