+* Wed Jul 20 2022 Jan Friesse <jfriesse@redhat.com> - 1.0-266.1.f288d59.git
+- Rebase to newest upstream snapshot
+- This version fixes a critical bug that caused the authfile directive
+  to be ignored. After installing the patched version, nodes may stop
+  communicating. Solution is to either remove authfile from configuration
+  file or update all other nodes.
