In general terms then would the plan be to make a good 0.14 release, and then merge the "Assembly/PartDesign" into master? Presumably master will then be a bit free for a while to be more "wild"/"dangerous"/"on-the-edge"/"compatibility issues" or whatever until Assembly is "better behaved" and more complete.
Regarding the OCC/OCE version...I think we need to focus on 6.7.0 or higher if at all possible, if for nothing else because the check geometry tool does not work well with earlier versions. It would seem logical to wait for the first bug release i.e. 6.7.1 if that is no too far away, since the "stable release" will probably be around a long time with Windows users. The point releases of OCC are, as far as I am aware, always compatible with the earlier point releases. The OCC version is a Windows specific issue, as on Linux it can be upgraded (within limits) being a lib in a different package.
I believe Juergen said a while ago something along the lines of the PartDesign improvements are not practical in include without the Assembly stuff. I think he said it was too much work to split it out...Werner seems in agree with that assessment, so presumably that matter is settled.
I was hoping Luke's new Drawing WB would be out in time but perhaps not?
I was also hoping the C++ spreadsheet stuff would be included, but that also perhaps not?
Obviously this is Yorik's baby, but I was wondering if he wants to get IFC import/export to some particular point of development and I think he might like "halfspace" resolved/implemented for 0.14?
