Are you thinking, “Gee, I wish I could help out with the LLVM 3.4 release, but I just don’t know where to start”? Well, ponder no more! You can grab both binaries and source code from this website:
http://llvm.org/pre-releases/3.4/rc1
Compile the sources yourself or use the binaries. Build your code and test to your heart’s content! 
Please file bugs if you hit any problems.
Share and enjoy!

Getting the source/binaries is easy. Getting the release notes seems hard. Anyone have a working link for 3.4 release notes? All of the 3.4 links don’t work. 3.3 links work and the main release notes pages have switched over to 3.5. Is there a working link anywhere or is this intended?

The release notes are in the 3.4 branch:
http://llvm.org/svn/llvm-project/cfe/branches/release_34/docs/ReleaseNotes.rst
similar for llvm. Please update them with current information!
