I have heard a lot of good stuff about DrumGizmo[0] lately, it has a very active development as well. Havent had the oppurtunity to try it out yet. But I have recently heard people moving from Hydrogen to DrumGizmo.
FreeCAD development have really picked up the pace lately. There is also a major overhaul of the partdesign workbench merged and underway for release 0.17. It brings user created datum points, axis and planes. It also brings advanced modeling features such as draft angles, shell and swept profile cut! Much to get excited about! :)
I am using Hugo on my personal site http://www.gntech.se and i Like it alot! Coming from Jekyll and Pelican I really appreciate the build speed and the minimal environment setup that is needed! Highly recommended tool!
