For now, it’s only a draft message on their arch-dev-public mailing list, but it will soon be published on the official Arch Linux website for all users, and it means that the forthcoming February 1, 2017, release of Arch Linux will be the last one provided as a dual-arch ISO image, for both 64- and 32-bit hardware platforms. Starting with the March 1, 2017, release, the official Arch Linux ISO won’t be a dual-arch one, but only a 64-bit image, which means that you won’t be able to install the operating system on a 32-bit computer, if you still have one of those around. However, 32-bit support for existing systems is not going away anytime soon.
