Well said!

Like many open source communities, pandemic had a pretty significant impact, but development and releases are quite active.

New release coming out in a few weeks introduces conversion support for 150 new geometry and terrain file formats. This summer, Physically-based Rendering support is coming to open source CAD for the first time ever. All the while, devs are working on GUI infrastructure, mentoring GSoC, doing academic research, interacting with academia, and doing what they can to help foster an open source CAx community.
