Cosmopolitan Libc transforms C into a versatile language that runs natively on multiple platforms without the need for an interpreter or virtual machine. It optimizes GCC and Clang to output a POSIX-approved format for Linux, Mac, Windows, and more with top performance and minimal footprint. Updates include a better memory map, updated Lua version, and enhancements to the C++ standard library. GitHub development process improvements have also been implemented. Explore the Cosmopolitan Third Edition, Cosmo README, and Cosmopolitan Toolchain README for more details. Some controversial aspects may include the reinventing of the C++ STL and various memory management changes.
