The Office team achieved the goal of providing technical documentation for the implementation of Office 2010 Beta. We published a total of 256 documents which included new and updated documentation for Office 2007 and Beta Office 2010 on MSDN.
We also rolled out the implementer notes for the IS29500 and ODF 1.1 specification on the DII (Document Interoperability Initiative) website.
