Issue 72 - June 11, 2008
---------------------------------------------------------------------------
Welcome to issue 72 of HWN, a newsletter covering developments in the
[1]Haskell community.
Greetings, Haskellites! As many of you have already heard, Don Stewart
has passed on the editorship of the HWN to me (Brent Yorgey). I'd like
to thank Don and John Goerzen for their great work putting it together
in the past, and I'm excited to make the HWN once again into a
reliable, useful compendium of happenings in the Haskell community. You
can expect to see a few changes---for example, hackage uploads will no
longer be listed in the HWN (unless they are announced on the haskell
or haskell-cafe mailing lists), since you can now see a dynamically
updated list on the front page of the Haskell wiki. This edition
includes all the announcements going back to Issue 71, but only some of
the blog posts, since I couldn't find a way to get old feed data from
Planet Haskell. Hopefully next week things will settle down to
something more normal(ish) and I can begin tinkering with the format.
Feel free to send suggestions and/or stories for inclusion to me,
byorgey at gmail dot com. Enjoy---'Putting the W back in HWN!'

[46]category-extras package, involving all sorts of new categorical
goodness.
Session Types for Haskell. Matthew Sackman [47]announced the

means of describing communication between multiple threads, and
statically verifying that the communication being performed is safe and
conforms to the specification.
Haddock 2.1.0. David Waern [49]announced the release of [50]Haddock
2.1.0.
