Where to find a zip file for 3.0.6

Does anyone know where to download the zip file for 3.0.6?  I can find build 3.0.4423 on the downloads page, but I can't find anything in the build itself to verify that this is 3.0.6.

(Yes, I'm aware that 3.5 is out, but I don't want to upgrade until I have the time to verify that this semi-major release doesn't break anything in a spectacular way.)
