v1.8.3

Changed

• Receiving from the SSL socket is now done with a lock to prevent sending and
  receiving at the same time (which can break with SSL). This should fix
  random disconnects with Ubuntu 22.04 / OpenSSL 3.
• Because of the above change, irc.sock is now non-blocking and things that
  call irc.sock.settimeout() may break the connection or cause deadlocks.
  • irc.sock hasn't been in the API documentation and has been deprecated
    for a while.
