        * `consul['configuration']['#{setting}']` has been deprecated since 15.5 and will be removed in 16.0. In GitLab 15.5 Consul version has been updated to 1.12.5, starting with which this setting has been moved to a different location. Hence, move this setting to `consul['configuration']['tls']['defaults']['#{setting}']`.
