I’ve been trying the latest version for a week or so now and am very impressed with the improvement. The biggest improvement is to the UI (user interface). It is much more intuitive and has more of a feel of Fusion or Solidworks to it. It has fixed the bug with tapered radial spokes that has been discussed here and the only other I’ve come across is in the Gears workbench which truncates cycloid gear teeth. However that is an independently produced addon and not really part of the main program.
For me the biggest advantage of FreeCAD is the there are releases for Windows, MAC, and Linux so I can run it on my Linux machine without relying on the cloud for Onshape.
