Up through 0.44 we've stuck to the Gtk 2.4 requirement, in order to minimize dependency problems for users. When we jumped from Gtk 2.0 to 2.4, a lot of users had installation troubles that we had to spend a lot of time helping with, so we wished to avoid that as long as possible.
Yet 2.8 has been out a while, and has some new capabilities that would be nice to rely on. 2.8 would be more compelling of a change than 2.6, so if we have to put people through the trouble of upgrading gtk, it might be better to move them to 2.8.
I'd like to propose that we change the dependency requirements for Inkscape to 2.8. Doing this right now gives us a maximum amount of testing time before 0.45.
Would anyone see an issue with doing this in this next release?
