The next major release on our roadmap is Duplicati 2.0. There is a preview release available. It comes with a new command line interface, a brand new user interface, a new storage engine and a built-in updater that keeps your preview release up-to-date.
Before 2.0 will be officially released, a few things need to be done:
We would like to get 2.0 released as soon as possible. But we develop Duplicati in our spare time which is limited. That is why we still cannot give you a release date.
