Cosmopolitan is a neat project that enables compiling a C program into a fat binary – a single executable file that runs on Linux, macOS, and Windows. Build once, run anywhere. Congrats, and thanks for all your work, Justine! 🎉

After a year of development, I've just published Cosmopolitan v3.0. The release notes are here. Now featuring arm support, fat binaries, and improved windows polyfills.
