## Headline Changes

- Duo two-factor support

    You can now add the new `authenticator_duo` stage to configure Duo authenticators. Duo has also been added as device class to the `authenticator_validation` stage.

    Currently, only Duo push notifications are supported. Because no additional input is required, Duo also works with the LDAP Outpost.

## Minor changes

- You can now specify which sources should be shown on an Identification stage.

This release does not introduce any new requirements.
