I have been looking for this, since I heard about it at TechEd 2005.
This release includes the following new features:
1. Support for multiple endoints pointing at a single document library folder
2. Dynamic send port support using the following syntax
3. Username, password, and domain support per endpoint
4. Binary file support
5. Receive adapter context properties set (Site, Folder, View, Name)
6. Send Port endpoint properties set (UserName, FileName, Site, Folder, etc)
7. Fixed "unable to process batch callback" error
