There are two new updates that I need to pass along. Hopefully, you have another source for learning about updates, but it never hurts to point out new updates. The first is a Cumulative Update for SQL server 2008 if you have SP1 installed:

The second is the Cumulative Update if you have only the RTM (Released to Manufacturing – the initial release of the product):
