A suggestion to include: I've recently been trying to adapt our project to LLVM 3.0 rc2, and it took me several hours to track down what happened to "include/llvm/Support/StandardPasses.h".  There is no mention of this topic in the current release notes page for 3.0 on the website (http://llvm.org/docs/ReleaseNotes.html#whatsnew), or the equivalent page in the kit itself.  And it isn't easy to find how it has transmogrified just by searching the LLVM sources, because all the old API function names have also changed.

I was finally able to track it down to the new header "include/llvm/Transforms/IPO/PassManagerBuilder.h" by looking at how the Clang usage had changed, where it previously had used StandardPasses.h and its contents.

So, for the release notes, it would be nice to mention this change and perhaps give a couple examples how to convert from calls to "createStandardModulePasses()" and "createStandardFunctionPasses()" to the new interface.  

Thanks for everyone's hard work on 3.0 - I can't wait to get our project building cleanly with rc2.
