Sorry to bother you with such matters, but I'm doing Fedora package review for a nettle 3.10 compat package inclusion (https://bugzilla.redhat.com/show_bug.cgi?id=2443729), and one of the checks in the review checklist is keeping up with FSF postal address. I know. > nettle3.10.x86_64: E: incorrect-fsf-address /usr/share/licenses/nettle3.10/COPYINGv2 > nettle3.10-devel.x86_64: E: incorrect-fsf-address /usr/share/doc/nettle3.10-devel/descore.README Seems like they've recently moved again indeed: https://en.wikipedia.org/wiki/Free_Software_Foundation#Postal_address_and_headquarters
