[boost] What is the status Property Tree Library?

I recall this library was accepted into boost: <http://thread.gmane.org/gmane.comp.lib.boost.devel/142785> but it seems it never made it into CVS? <http://thread.gmane.org/gmane.comp.lib.boost.devel/148783> With 1.34 out the door and 1.35 to follow soon ;) it would be nice to have a current status of libraries that are supposed to make it into 1.35. It's possible I have missed this but I thought I'd post just in case. Thanks, Jamie
