Not exactly. What I changed is that setuptools always interpreted a '-' as indicating a post-release patch. This meant that if you put a '-' before 'rc' or 'beta' or whatever, it was still considered a *post*-release, which caused all the CherryPy upgrade problems. Setuptools always interpreted numbers like '2.1.0rc2' or '0.2b5' correctly; it was only the inclusion of a '-' that threw it off. Now, the '-' is ignored if it precedes something that would otherwise be considered a pre-release like 'rc' or 'b'. Note that this means that using the very latest (i.e. today's version, 0.6a9dev-r41630) setuptools (ez_setup.py setuptools==dev) is necessary if you're upgrading CherryPy or trying out the new Subway release, as both have the problematic '-rc' versions out there. When CherryPy did it, I sort of assumed it was a fluke. When Subway did it too, it made it abundantly clear that the dash-is-postrelease logic was not intuitive, and I had a flash as to how I could fix it in a way that hopefully won't break anything else. :)
