Send/Recv often needs to be called multiple times to transfer all of the data. send_raw/receive_raw are now mutex protected and so both send & receive can be called simultaneously.
Sockets will immediately return fr::Socket::Status::Disconnected if an attempt to send/receive data is made whilst the connection is closed.
Added SocketReactor, which is effectively a little wrapper around fr::SocketSelector, but can automatically call a callback for a socket when data is received on it.
You can now accept SSL connections using SSLListeners, and then send/receive data through the associated SSLSocket.
HttpSocket's now support both HTTP and HTTPS, using templates:
fr::HttpSocket<fr::SSLSocket> https_socket;
fr::HttpSocket<fr::TcpSocket> http_socket;
