Microsoft SQL Server 2008 R2 Release to Manufacturing (RTM)
Go find out all the goodness of the release at https://www.microsoft.com/sqlserver/2008/en/us/R2.aspx
My personal favorite? Self-service business intelligence. Anything that empowers end-users is a win for me, and this one simultaneously gives IT more oversight and control of what's happening with the data that runs their business.
Enjoy!
