I was rather surprised to see: https://admin.fedoraproject.org/updates/F9/FEDORA-2009-6661 https://admin.fedoraproject.org/updates/F10/FEDORA-2009-6076 https://admin.fedoraproject.org/updates/F11/FEDORA-2009-6370 Where the automake was upgraded to 1.11 for F9, F10, and F11. In general automake hasn't had a very good track record of compatibility between 1.x and 1.y, though this has been getting better recently. I don't see any specific mentions of incompatible changes in a quick scan of: http://lists.gnu.org/archive/html/automake/2009-05/msg00093.html But it is also a pretty long release announcement so it wouldn't surprise me if there were some subtle incompatibilities. The only breakage I'm actually aware of in the gnome-common package; gnome-common-2.26 and earlier doesn't know that automake-1.11 is a valid replacement when automake-1.10 is asked for. So, we definitely need to release an update for gnome-common, or people aren't going to be able to do GNOME development on F11. But is this the type of upgrade that makes sense in general? It seems to me that we should be very conservative in upgrading build tools, especially in "maintenance mode" distributions like F9 and F10. - Owen -- fedora-devel-list mailing list fedora-devel-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/fedora-devel-list
