Which releases do you need this updated on?  I just reviewed the changes in the package.  I can definitely push this to rawhide and I'm willing to push it to F18.  I can be convinced to push it further back but there is one backwards incompatible API change so I'd like to know if it was needed first.

I was going to push the new package to at least F17, but I don't really mind if we stop at F18. 

The bug in question affects python3 only so we will still have a working package with python2

It's fine with me to push to F17.  I'll leave it in updates-testing for the full two weeks (for F17) but there's a straightforward fix if there's any problems.

(The package dropped a partial function that was used as backwards compat on older versions of python.  Since all current Fedora uses python-2.7, people can just port their code to try importing partial from the stdlib first.)
