That list is currently being worked on by many peoples. Also, there are some parts on that list, which have not been adressed yet.

But as far as versions go, it was agreed at SFEU17, that all dependencies for 2.4 must be set for 2.6 as well. 3.0 is when we cut off, and for now, I would keep it that way.

2.6 should be the final LTS for gtk and qt4.8

Stig documented on January 13th a list of issues which should be attended too before branching of 2.6 would be prudent. I see that translation stuff is being addressed, the rest I haven’t looked at yet. Let’s seriously look at this list and come to a conclusion.
