In previous versions, you had to configure email connection details per [Email Stage](../flow/stages/email/index.md). Now, you can (and should) configure global settings.
This is documented under the [docker-compose](../installation/docker-compose.md) and [Kubernetes](../installation/kubernetes.md) sections.
- New notification system
More info can be found under [Notifications](../events/notifications.md) and [Transports](../events/transports.md).
During the update, some default rules will be created. These rules notify you about policy exceptions, configuration errors and updates.
These notifications will be sent using a default transport, which uses the global email transport.
Download the latest docker-compose file from [here](https://raw.githubusercontent.com/goauthentik/authentik/version-2021.1/docker-compose.yml). Afterwards, simply run `docker-compose up -d` and then the standard upgrade command of `docker-compose run --rm server migrate`.
