The following features are new in Service Pack 1 ( See Release Notes):
- Slipstreaming is an installation method that integrates the base installation files for a program with its service packs and enables them to be installed in a single step. You can slipstream a SQL Server 2008 update and the original installation media so that original media and the update are installed at the same time. The update setup documentation available from the Download Center has the most recent description of the slipstream process. The update setup documentation is also available at MSDN.
- You can uninstall SQL Server 2008 cumulative updates or service packs from Programs and Features in Control Panel. For more information, see “Overview of SQL Server Servicing Installation” in the update help file.
- SQL Server 2008 Service Pack 1 provides a ClickOnce version of Report Builder 2.0. Report Builder is available for use in Reporting Services (SSRS) installed in native or SharePoint integrated mode. If SSRS is installed in SharePoint integrated mode, you need to install the add-in, Microsoft SQL Server 2008 Report Builder 2.0 ClickOnce for SharePoint, to make Report Builder 2.0 ClickOnce available from a SharePoint site. For more information, see the Report Builder 2.0 ClickOnce for SharePoint Readme.
