It is an independent rewrite of MSys, based on modern Cygwin (POSIX compatibility layer) and MinGW-w64 with the aim of better interoperability with native Windows software. Both 32-bit and 64-bit variants exist and receive mostly the same level of support.

The MSYS environment contains the unix-like/cygwin based tools, lives under /usr and is special in that it is always active. All the other environments inherit from the MSYS environment and add various things on top of it.

Updating MSYS2. After you have installed MSYS2 via the installer or other means, you need to continue updating it with the built-in pacman tool. MSYS2 is a rolling release distribution and only supports full system upgrades, which means there are frequent minor and major updates to various packages and you can only update all packages at once.. To update all packages run the following command:

Msys/Cygwin Packages: Requires 64-bit Windows 8.1 / Windows Server 2012 R2. Mingw Packages : Requires 64-bit Windows 8.1 / Windows Server 2012 R2. Upstream software may impose additional requirements.

What is MSYS2? MSYS2 isn't "one tool to rule them all", but tries to focus on what it's good at. It provides a native build environment, based on open source software, and makes you feel right at home when you are already comfortable with Linux.
