```
old fdSocket :: Socket -> CInt
new fdSocket :: Socket -> IO CInt

old mkSocket :: CInt -> Family -> SocketType -> ProtocolNumber -> SocketStatus -> IO Socket
new mkSocket :: CInt -> IO Socket
```
* Breaking change: the deprecated APIs are removed: send, sendTo, recv, recvFrom, recvLen, htonl, ntohl, inet_addr, int_ntoa, bindSocket, sClose, SocketStatus, isConnected, isBound, isListening, isReadable, isWritable, sIsConnected, sIsBound, sIsListening, sIsReadable, sIsWritable, aNY_PORT, iNADDR_ANY, iN6ADDR_ANY, sOMAXCONN, sOL_SOCKET, sCM_RIGHTS, packSocketType, getPeerCred.
