Following 9 months of [deprecation period], support for the i686 architecture effectively ends today. By the end of November, i686 packages will be removed from our mirrors and later from the packages archive.
For users unable to upgrade their hardware to x86_64, an alternative is a community maintained fork named [Arch Linux 32]. See their website for details on migrating existing installations.
