Erlang/OTP 22.3 is the last planned patch package for the 22 major release with new features, improvements and bugfixes. Below follows some highlights.

Highlights

  • ssl/public_key:
    • Implementation of the key and initialization vector
      update feature, and general hardening of TLS 1.3.
      There are cryptographic limits on the amount of
      plaintext which can be safely encrypted under a given set of keys.
      This change enforces those limits by triggering
      automatic key updates on TLS 1.3 connections.
    • Add support for TLS 1.3 Session Tickets (stateful and
      stateless). This allows session resumption using keying
      material from a previous successful handshake.
    • Add support for key exchange with Edward curves and
      PSS-RSA padding in signature verification.
  • erts:
    • A socket "registry" has been added making it possible to list current open sockets.
    • Add a "full featured" version of getifaddrs in the net module.
  • ssh:
    • The new functions ssh:set_sock_opts/2 and ssh:get_sock_opts/2 sets and reads option values for
      the underlying TCP stream.
    • Changes to the internal api of the experimental ssh_dbg tool.
  • common_test: The ct_property_test has now a report function for
    results of stateful testing.
  • stdlib:
    • Implement uri_string:resolve/{2,3} that can be used to
      resolve a URI reference against a base URI.
    • In gen_statem it is now possible to change the callback
      module for a running server. See gen_statem's
      documentation for change_callback_module,
      push_callback_module, and pop_callback_module.
