I think it is not a bad time to review and discuss about what might go into 0.15 and what not, even if a release will not happen right now. Last time it took roughly three months from the start of the discussion to the actual release (but this was a pretty big one).
I went over the 0.14 thread and tried to distill the things that were postponed or discussed. I don't closely follow all the developments (there are so many), so some of that might already be integrated.
- new Part Design (body feature, datum planes)
- new Drawing WB
- C++ Spreadsheet
- Arch halfspaces
- new OCC/OCE Versions
I wanted to integrate BOLTS into FreeCAD. It should not be too much effort, but I haven't really started yet, so depending on the timescale for 0.15, it might not be ready.
Then there is the freshly announced Oculus Support by Jürgen. I don't know how well one can expect to get it tested, given the limited availability of the Oculus Rift. Probably Jürgen has to decide whether it should go into 0.15 or not. But it would definitely be a very spectacular feature that would create a lot of buzz.
