Welcome to issue 162 of the HWN, a newsletter covering developments in the [1]Haskell community in the week of December 05 - 11. Wouter Swierstra [2]sent a call for papers for the ICFP 2011 to be held in Tokyo, Japan between September 19 - 21. The announcement contains all relevant dates of importance Dmitry Astapov [3]announced the realease of haskell-mpi, "a suite of Haskell bindings to the C MPI [Message Passing Interface] and convenience APIs on top of it." David Waern [4]annouced a new version of the venerable Haddock. "This version is compatible with .haddock files produced by the version of Haddock that comes with GHC 7.0.1." Michael Snoyman [5]announced the first release of his library and executable packdeps. "This is a library and executable containing the same functionality as the original packdeps website, namely letting you know when your version bounds exclude the use of the newest version of a library available." Michael also [6]announced the second major release of the mime-mail library. This "is a package providing support for rendering multipart emails." Jasper Van der Jeugt [7]announced the 0.0.2.0 release of the digestive functors library. "The library provides a general API to input consumption, and is an upgrade of formlets." So, what went on this week?
