  [#368](https://github.com/haskell/network/pull/368)

## Version 3.0.0.0

* Breaking change: the Network and Network.BSD are removed.
  Network.BSD is provided a new package: network-bsd.
* Breaking change: the signatures are changed:
```
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.

  on the Ord instance. Now PortNumber holds Word16 in host byte order.
  [#347](https://github.com/haskell/network/pull/347)
* Breaking change: stopping the export of the PortNum constructor in
  PortNumber.
* Use bytestring == 0.10.* only.

   exceptions when necessary.
