I'm happy to announce the release of network 3.1.2.0. https://hackage.haskell.org/package/network-3.1.2.0 This version of network includes many improvements that allow more extensibility, portability, and greater test coverage. See the log below for more information. As well version 3.1.1.0 and 3.1.1.1 have been deprecated as they contain a bug in graceful close, more details below. - Added -f devel for test cases that are known to fail. #471 https://github.com/haskell/network/pull/471 - Improved precedence-compliant Read/Show instances.
