Tor is and has always been end-to-end encrypted. What do you mean?
It's not encrypted between the Ricochet process and the Tor process (which is a point for potential improvement), but if you don't trust your local machine you've already lost.
That would be news to me. Since when is the traffic leaving the exit node encrypted?
(how could it be?)

When talking to a hidden service, there is no exit node, and no traffic leaving the tor network.
But not end-to-end encryption ... (unless Tor changed that?)
