As promised, Microsoft has released SP1 for Office 2007 today, available on their Office download site. At the same time, Microsoft has released SP1 for Visio 2007 and Project 2007.
The Office 2007 SP1 link, which was dead until just a few minutes ago, is now live, and is here. As I indicated earlier, for now, due to recent concerns over Automatic Updating, this will be a manual-only install.
Did we ask about the Ribbon yet? Based on the linked whitepaper, it doesn't look like turning off the oft-criticized Ribbon is a new option. Heavy sigh.
