we are about to release privacyIDEA 3.5, which enhances the 4-eyes token, adds support to enroll Yubikey as a smartcard (at least test the attestation certificate) and many enhancements with the UI, the dashboard, policies and events.
We are in the feature freeze and current not adding any more code.
See the changlog here:
We will now also provide packages for Ubuntu 20.04!
