Big news! The long-awaited release of WSS/MOSS SP1 has hit the streets. And this is a doozie of a service pack. So big that a page on TechNet has been created to guide you through it: http://technet.microsoft.com/en-us/office/sharepointserver/bb735839.aspx. Note! Even the product team is saying “be thoughtful” here. Per Joel Oleson, “It is essential that you understand the appropriate guidance and test out the patch in a separate test environment.” Spend the time it takes to evaluate the SP—don’t just roll it out.
