+Extra-ATC freeze
+--------------------------------------

+All contributions to OpenStack are valuable, but some are not expressed as
+Gerrit code changes. That allow teams to list active contributors to their
+projects and who do not have a code contribution this cycle, and therefore won't
+automatically be considered an Active Technical Contributor and allowed
+to vote. This is done by adding extra-atcs to
+https://opendev.org/openstack/governance/src/branch/master/reference/projects.yaml
+before the Extra-ATC freeze on 25 February, 2021.
