Fedora 31, due for release on October 29th, will no longer be available as a 32-bit install. Rather, Fedora 30 is officially the last version of Fedora to support 32-bit hardware. Users on legacy hardware can expect full lifecycle support for Fedora 30 until May or June of 2020, at which time they will need to upgrade their hardware for continued official support.
