The Microsoft SharePoint Product Group and the Microsoft Office Service Pack Team announced the Service Pack 2 for Microsoft Office System which will be released between February and April 2009. Some SharePoint-related highlights that we could expect are:

1. Performance and manageability improvements including STSADM commands for repairing links between source and target pages.
2. Improvements to read-only content databases and index rebuild timer jobs.
