+    BREAKING CHANGE:
+
+    The `ludusavi` module has changed its default backup and restore path.
+    The new module implements a mechanism to automatically migrate the backups
+    to the new path, but if it doesn't work and you can't find your backups in
+    `ludusavi`, they should be in the old path: ~/\$XDG_STATE_HOME/backups/ludusavi/
+    (that means a directory literally called $XDG_STATE_HOME in your home, rather than
+    the env var expanded). For more info, see pull #8234.
