This is not just a bug fix.  Look at the list of all the new features.

Microsoft announces the availability of SQL Server 2005 Service Pack 1 (SP1) with Database Mirroring, SQL Server Management Studio Express, additional options for ISVs and normal feature fixes.

This is the first major milestone for SQL Server 2005 since the launch last November which attracted more than 300,000 attendees at 307 launch events, held in 247 cities across 92 countries.

The release of SQL Server 2005 SP1 follows the March 2006 Community Technology Preview (CTP) and the initiation of a new customer collaboration model, which allowed active customer feedback to drive final updates and routine fixes delivered in this service pack.

SQL Server 2005 includes functionality for the largest enterprise to the smallest hobbyist, non-professional or ISV, delivering on the team’s vision to provide a complete data platform for all users of every size.
