"The ReactOS project is proud to announce the release of version 0.3.15. A culmination of over a year of development, 0.3.15 incorporates several architectural enhancements to create a more compatible and conformant implementation of the NT architecture. Perhaps the most user visible enhancement is initial support for USB devices, both storage and input. Infrastructure wise, this is the first release of ReactOS using CMake instead of rbuild. The conversion to CMake has allowed developers to generate Visual Studio solutions for working on the code, though several C++ components still need work before support for Microsoft's toolchain is complete."
