Last month saw the final adoption, after 4 years of work, of TLS version 1.3 by the Internet Engineering Task Force (IETF).

This is a very important security property, because without forward secrecy, if a server’s private key is compromised today, any previously-recorded conversations with that server dating back as long as the key was in use could be decrypted.
