Announcements
----

Cabal-1.6.0.2 and cabal-install-0.6.2. Duncan Coutts announced  point-releases of the Cabal library and the cabal-install command line tool. These releases include a number of fixes and minor improvements, and are expected to be included with ghc-6.10.2.

Barrie 0.3.1. Fraser Wilson announced a hackage release of Barrie, an implementation of an idea for supporting state based, user-driven GUIs.

wxFruit-0.1.2. Henk-Jan van Tuyl announced  an update of wxFruit, a graphical user interface that combines some of the power and versatility of wxHaskell with the elegance and simplicity of Fruit. The new version works with GHC 6.10, and also includes a demo game, PaddleBall. Interested parties, take note: the position of developer/maintainer for this library is currently open.

pqueue-mtl, stateful-mtl. Louis Wasserman announced  two new packages, stateful-mtl  and pqueue-mtl. stateful-mtl provides an ST monad transformer, several useful operations on generic monad transformers, and a monad transformer intended to cleanly externally wrap operations on a mutable array (including resizing operations). pqueue-mtl provides implementations of several structures supporting a generic 'single-in, single-out' paradigm (encapsulated in a typeclass named Queuelike), including stacks, queues, and several implementations of priority queues.

haha-0.1 - Animated ascii lambda. Sebastiaan Visser announced haha, a very minimal vector based ascii art library written just for fun. If you've always wanted to have a full-color rotating vector based ascii art lambda on your terminal, now is your chance!
