Attention une mise à jour du service Gitlab va être effectuée le mardi 30 novembre entre 17h30 et 18h00. Cette mise à jour va générer une interruption du service dont nous ne maîtrisons pas complètement la durée mais qui ne devrait pas excéder quelques minutes. Cette mise à jour intermédiaire en version 14.0.12 nous permettra de rapidement pouvoir mettre à votre disposition une version plus récente.
