+### Upgrade Notice
+
+If you're upgrading from an earlier version, make sure to delete your
+`bootsnap` cache, to avoid a load error (see
+[this issue](https://github.com/ontohub/graphql-pundit/issues/51)).
+The cache files are usually located in the `tmp` directory in your
+repository and are named `bootsnap-compile-cache` and
+`bootsnap-load-path-cache`.
