Version of gtk+ to shoot for in Gnome 2.18?

["Elijah Newren" <newren gmail com>]

Hi,

http://live.gnome.org/TwoPointSeventeen/Platform currently lists HEAD
for the version of gtk+ to use for 2.17.x.  Should this be gtk-2-10
instead, or is there a tentative timetable for gtk+ 2.12 with a date
far enough in advance of Gnome 2.18.0?  (I couldn't find one at
http://www.gtk.org/plan/, so I'm asking here)

Thanks,
Elijah
