As for the language itself, I can manage with 2.5. It's the libraries that are occasionally an issue. I have only ever seen the module gtkmozembed in Python 2.6. It usually comes in the python-gnome2-extras package. However, it's not in the python2.5-gnome2-extras in Fremantle. It's probably not an issue of the version of Python per se, but rather than no one ever made gtkmozembed for 2.5. Or, I just failed to find it. If it's available for Fremantle, I'd sure like to know about it.
