bloxorz clone. Patai Gergely announced a Haskell clone of the game "bloxorz", written by Viktor Devecseri.

Fun with type functions. Simon Peyton-Jones announced that he, Ken Shan, and Oleg have finished Version 2 of their paper "Fun with Type Functions", which gives a programmer's tour of what type functions are and how they are useful. If you have a moment to look at, and wanted to help them improve it, leave comments on the linked wiki page.

package Boolean: Generalized booleans. Conal Elliott announced Boolean, a new package for generalized booleans, which provides type classes with generalizations of Boolean values and operations, if-then-else, Eq and Ord.

TernaryTrees-0.1.1.1 - An efficient ternary tree implementation of Sets and Maps. Alex Mason announced the release of TernaryTrees, a package that extends Data.Set ad Data.Map with some ternary tree structures, one of the more efficient ways of storing strings in a set.

regular-0.1. José Pedro Magalhães announced the release of the regular library. Many generic programs require information about the recursive positions of a data type, such as generic fold, generic rewriting, and the Zipper data structure. Regular provides a fixed point view on data which allows these definitions for regular data types. It also serves as the basis for a generic rewriting library.
