Development on Path seems to be moving ahead but also appears sporadic. It's difficult to keep up with the status of various projects so I thought to do a periodic 'digest' of activity. I'm summarizing things as I see them (strictly an end-user's point of view). Please reply to this thread if you're working on anything related to the Path workbench. A more detailed update of any of these items is welcome.
Regular profiling works by selecting a face. Simplest cases work well but many of the options don't work at the moment. Particularly troubling is that the user can't select which side of a face to profile. So if the face has a hole, the profile will always select the outside edge of the solid and the user can't select the edge of the hole.
Pocket operation isn't really useful yet but Is functional as a demonstration. Most options and parameters haven't been enabled yet but I've been able to produce a crude tool path.
Libarea is the profiling and pocketing operation used in HeeksCNC. It's stable, fast, and is license compatible with FreeCAD. Dan Falck has integrated libarea into Path so it's automatically installed with FreeCAD. (DAN: you can probably give a much better summary)
operation partially working. Instead of selecting a face to profile, the user selects individual edges. This works for individual contiguous edges but not for circular edges or multiple disconnected selections.
. Planned but not started.
Roland Modela MDX - user jonner working on this.
Maho CNC - user chrisb working on this and has done some work to make the post processors customizable by regular humans.
prrvchr is building a workbench to communicate with an arduino via PySerial USB. This will be useful to stream GCode from Path to an external device.

Even with Path still limited in functionality, I was able to make a simple project.
