+        Do not submit bug reports about anything but the two most recently released *major* systemd versions upstream!
+        If there have been multiple stable releases for that major version, please consider updating to a recent one before reporting an issue.
+        When using a distro package, please make sure that the version reported is meaningful for upstream.
+        If a distro build is used, please just paste the package version, e.g. `systemd-250.7-1.fc36.x86_64`.
+        See https://github.com/systemd/systemd-stable/tags for the list of most recent releases.
