gtk+ roadmap?

[Louis E Garcia II <louisg00 bellsouth net>]

I believe Yang JianJun is working on the xcb port of gtk and wanted to
know how it's coming? Their has been talk of possible abi compatibility
problems with xlib. I wonder if this would be a good time for a abi/api
break 3.0 release. Their are many performance optimizations and cleanups
that can be made to gtk core but can't do to abi compat. What is the
current thinking with project topaz and gtk 3.0?
