+
+  See https://github.com/openSUSE/systemd/blob/SUSE/v253/NEWS for details.
+
+  * Rebased 0001-conf-parser-introduce-early-drop-ins.patch
+
+  * Ship systemd-journald-audit.socket again: it can now be disabled via the
+    usual "systemctl disable" mechanism to stop collection of audit
+    messages. Note that it's handled by the preset logic, which turns it off by
+    default.
+
+  * TEST_06_SELINUX needs selinux-policy-devel.
