A key milestone for Microsoft Office was the release of the Technical Preview for Microsoft Office 2010 on the 13th of July 2009. Another key highlight was the release of the Office 2010 Beta documentation on MSDN and the release of the implementer notes for IS0/IEC 29500 and ODF 1.1.
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.
