- win32 and x64 are now separate platform build targets, so no more nasty hacks to swap between them.
- class diagram view is a very powerful new feature which allows you to see the design of your software in a uml class diagram and I'm sure that for C++ programmers who like me are conscious of software architecture it will prove to be an often used feature.
- debugger enhancements make debugging multithreaded software a fair bit easier with the ever-so-handy 'Debug Location' toolbar.
I know this doesn't sound like a huge amount, but I just recently upgraded my Visual Assist to 10.4 (with vs2008 integration) and the new VA Outline feature slots in nicely with these new features in VS2008.
