Lots of Good Stuff at MSDN

Web Services Enhancements 1.0 for Microsoft .NET (WSE) is released. This provides advanced Web services functionality for Microsoft Visual Studio .NET and Microsoft .NET Framework developers to support the latest Web services capabilities. Previously known as Web Services Development Kit Technology Preview (WSDK), this version allows Enterprise ready applications to be developed quickly with the support of security features such as digital signature and encryption, message routing capabilities, and the ability to include message attachments that are not serialized into XML. Functionality is based on the WS-Security, WS-Routing, WS-Attachments and DIME specifications.

Also a new article on What's New for "Office 11" Developers?, Some salient features: XML as Native File Format, Support for XML Schemas, and the biggest one, Visual Studios Tools.
