If not, we should maybe add a proper remark about that to our support policy...? Also, some of our docker containers (tests/docker/dockerfiles/debian9*) are still using Debian 9 and are now used in our Gitlab-CI for our MinGW cross-compiler builds (I think also in the Shippable-CI, but I don't use that, so not sure about that one) ... if we don't support Debian 9 anymore, we should update these to a newer version. Any volunteers? Thomas
