   * The ``pip`` requirements upgrade checks now do not output warning
     in case deployed ``.in`` file does not have a matching ``.txt``
     file.
+  * Certificate expiration check is less verbose. No mails are sent
+    out any longer in case no certificates have been configured for
+    checking, nor in cases where all certificates have passed the
+    check. E.g. mails are sent out only in case some of the configured
+    certificates will expire within next 30 days.
