Microsoft is expected to release Service Pack 1 for Office 2007 on December 11. The release is expected to provide improved support for VSTO, coding improvements in the form of better object module documentation and improved support for .NET 3.5; improvements to the animated type in PowerPoint; backwards compatibility with older Office document formats; and improvements to the DirectX video overlay. The service pack will also include bug fixes and security patches.

Office 2007's SP1 will not be pushed out to users via Microsoft's automatic update service. Users may download the service pack and test it before rolling it out broadly. Microsoft is taking this approach in response to customer concerns about compatibility.
