Changes

Version 2.6.3.1

Reverse breaking exception change in Network.Socket.ByteString.recv #215

Version 2.6.3.0

New maintainers: Evan Borden (@eborden) and Kazu Yamamoto (@kazu-yamamoto). The maintainer for a long period, Johan Tibell (@tibbe) stepped down. Thank you, Johan, for your hard work for a long time.
New APIs: ntohl, htonl,hostAddressToTuple{,6} and tupleToHostAddress{,6}. #210
Added a Read instance for PortNumber. #145
We only set the IPV6_V6ONLY flag to 0 for stream and datagram socket types, as opposed to all of them. This makes it possible to use ICMPv6. #180 #181
Work around GHC bug #12020. Socket errors no longer cause segfaults or hangs on Windows. #192
Various documentation improvements and the deprecated pragmas. #186 #201 #205 #206 #211
Various internal improvements. #193 #200

Version 2.6.2.1

Better detection of CAN sockets.

Version 2.6.2.0

Add support for TCP_USER_TIMEOUT.
Don’t conditionally export the SockAddr constructors.
Add isSupportSockAddr to allow checking for supported address types at runtime.
