One more fun fact:

SolveSpace officially is supported on Windows (Vista-11), Linux and macOS, and compiles with Emscripten and runs in a browser.

However with a little effort it also compiles for and runs on Windows 2000.

So it runs on all the majour platforms from the last 26 years (excluding MacOS 9).
