SQL 2008 Service Pack 1 RTM now available
Service Pack 1 for SQL Sevrer 2008 is now available (download link below). Two of the key features in this are the ability to slipstream the service pack with the RTM media to provide a prepatched install (which I tested during the CTP and seems to work great although it's a bit manual) and the ability to uninstall the service pack (will try this soon and report back) which should hopefully provide a quicker backout than the previous uninstall/reinstall route.
