Debian Development team announced on May 07, 2016. Stating that they are going to drop the i386 architecture support on Debian 9 (stretch) release cycle. It was decided on last year to increase the minimum CPU features for the i386 architecture to 686-class. This means dropping support for 586-class and hybrid 586/686 processors[1].(Support for 486-class processors was dropped, somewhat accidentally, in squeeze.)
