 - The `plugin:list` command no longer outputs the version for the `plugn` binary.
 - Users building docker images that run Dokku will need to use a new sudoer wrapper for the `docker-image-labeler` binary to work correctly. A reference version has been placed in the `docker` skeleton directory. This should only impact platform developers, and users of our Docker image will already have the file available.
+- The `dokku` user's cron is now in use by Dokku itself. Customizations will be overwritten. Users are encouraged to use a cron entry in `/etc/cron.d/dokku` to avoid this issue.
