> Network encryption: built-in TLS support encrypts database connections

> RethinkDB 2.3 includes TLS support, contributed by Josh Hawn. Josh integrated OpenSSL, enabling encryption on the wire for both the client driver protocol and communication between database servers in a cluster. This update also brings encryption to RethinkDB’s web-based administrative user interface, which you can now access with an HTTPS URL.

Yay! WAN Replication over TLS is built in now.

I'm not sure how I feel about the web interface, might be better to stick with SSH tunneling for that.
