This pre-release is mainly for our Linux users.
It provides our first AppImage for Linux, which will be built now automatically with each push to master.
The latest build for Linux will be available at Continuous Build from now.
There were also some notable improvements from libdxfrw, which should make DWG reading more stable. This is attractive for all user.
macOS users please take care, that there are 2 packages, one for Big Sur and one for older ones.
Probably the Big Sur package runs on Monterey too, if not, please report in the forum or open an issue here.
