Arch Linux 2017.02.01 was the last monthly ISO snapshot released with 32-bit support, as all ISO snapshots that followed included only 64-bit packages, but existing 32-bit installations were still supported for a 9-month period during which users were had to move to 64-bit. That support ends today, November 8, 2017, effective immediately, and all 32-bit (i686) packages will be removed from the Arch Linux’s mirrors by the end of the month, as well as from its repositories by the end of the year.
