HTTPS problems after upgrading to 10.0.3

After upgrading my omnibus-gitlab-ce to 10.0.3, folks accessing git via https from certain (older) servers started reporting failure. This was reported as working prior to the upgrade. Access from newer linux boxes and OSX laptops seems to work, as does normal ssh access. Are there any new options which might be on by default with stricter checking on SSL or protocol restrictions?
