the right answer is of course to move the documentation over to an 
environment that can track such changes, and render things dynamically 
based on whatever version/platform the user's interested in.

moving the reference portions of the documentation into the source files 
might also be a pretty good idea (DRY!).  I'd say a suitable requirement 
for 3.0's standard library is that you should be able to do this:

     import module
     import docgenerator
     model = docgenerator.getinfomodel(module)

and get an information model that contains enough information to 
generate a manual page that's at least as good as your average library 
reference latex page.

I'll prepare a draft PEP when I find the time.
