Unless I'm missing something here, you've got two options before you break 
your users:
   1. fix your code before you ship it to them
   2. don't upgrade

Yes, you could say that the same applies to PyLucene, of course :-)

I'm not exactly sure what kind of backwards compat promises Lucene Java made 
going from 3.0 to 3.1 but the new QueryParser method overloads and the fact 
that there is no support for method overloads in Python make 
PythonQueryParser a bit stuck between a rock and a hard place. If you see a 
better way to fix the mess with the _quoted and _slop variants for 
getFieldQuery, a patch is welcome.
