+* Mon Sep 14 2015 Frantisek Kluknavsky <fkluknav@redhat.com> - 1:6.0.0-13
+- do not package sse2 variant, use --enable-fat instead (a bit dangerous, some low level routines will be skipped in `make check`)
+
 * Fri Sep 04 2015 Michal Toman <mtoman@fedoraproject.org> - 1:6.0.0-12
 - Add support for MIPS architecture to gmp.h and gmp-mparam.h
