CiviCRM 4.7.x has made significant progress towards supporting PHP 7, MySQL 5.7, and Ubuntu 16.04. I'm pleased to announce the availability of the release-candidate for v4.7.12.
These improvements were made possible with the collaborative efforts of several people and organizations, including Mark Burdett (EFF), Mattias Michaux, Seamus Lee (Australian Greens), the New York State Senate, and the CiviCRM core team (Jitendra Purohit and me).
