I have been working on getting OCC 7.2 into the PPA but it's slow going because I'm new to Debian packaging and it's quite complex, although I don't think it has any explicit blockers.
The main objective I've been researching is making sure 0.17 gets into Ubuntu 18.04, which means it needs to be in Debian Unstable by March 1st. However, I believe it would need to be the Qt5/PySide2 version there (https://tracker.debian.org/pkg/freecad
) so that kinda complicates things without a PySide2 release.
I think for Ubuntu 16.04 a release could more or less be done by moving stuff from the daily PPA to the stable PPA. I don't use 14.04 so I'm not sure on that front.
I can't speak for release readiness on Windows/Mac either so if someone wants to chime please do.
