Announcements
----

  xmobar-0.9.2. Andrea Rossato [2]announced the release of
  [3]xmobar-0.9.2, which features a fix for a longstanding resource
  leakage bug, new nested color definitions, and more.

hmatrix-static: statically-sized linear algebra. Reiner Pope
  [6]announced the release of [7]hmatrix-static, a thin wrapper over
  Alberto Ruiz's excellent [8]hmatrix library for linear algebra. The
  main additions of hmatrix-static over hmatrix are that vectors and
  matrices have their length encoded in their types, and vectors and
  matrices may be constructed and destructed using view patterns,
  affording a clean, safe syntax.

  haskellmode for Vim now at projects.haskell.org. Claus Reinke
  [9]announced that the Haskell mode plugins for Vim have just completed
  their move to their [10]new home, and took the opportunity to reiterate
  what they can do (quite a lot, it seems), and mention that some
  screencasts are available.

  Yogurt-0.4. Martijn van Steenbergen [15]announced version 0.4 of
  [16]Yogurt, a functional MUD client. Version 0.4 makes Yogurt available
  as a standalone executable that is able to dynamically load and reload
  Yogurt scripts.

  Elerea, another FRP library. Patai Gergely [17]announced the release of
  [18]Elerea, aka "Eventless reactivity", a minimalistic FRP
  implementation that comes with a convenient applicative interface,
  supports recursive definition of signals and signals fed from outside
  by IO actions, plays nice with resources, and is the result of some
  furious hacking. There are working examples to show off the current
  capabilities of the library, found in the separate [19]elerea-examples
  package.

  tree-monad 0.2. Sebastian Fischer [20]announced version 0.2 of the
  [21]tree-monad package, which provides instances of MonadPlus that
  represent the search space of non- deterministic computations as a
  tree. Version 0.2 implements an optimized CPS version of the tree.

  HCard -- A library for implementing card-like structures.. Joe Fredette
  [22]announced the release of [23]HCard, a library which supports a
  card-like data structures and uses associated types to provide
  shuffling, dealing, and other facilities. It's general enough to
  support many different types of playing cards; it currently comes with
  the common "French Deck" (4-suit, 13 card deck that is very common in
  the US) implemented and an example cribbage scoring application.

  SVGFonts 0.1. Tillmann Vogt [24]announced his first Haskell library,
  [25]SVGFonts 0.1, which parses the relatively unknown SVG Font format
  to produce outlines of characters. The big advantage of this format is
  that it is XML, which means easy parsing and manipulating.

  network-bytestring 0.1.2. Johan Tibell [26]announced a new release of
  [27]network-bytestring, a Haskell library for fast socket I/O using
  ByteStrings. New in this release is support for scatter/gather I/O
  (also known as vectored I/O). Scatter/gather I/O provides more
  efficient I/O by using one system call to send several separate pieces
  of data and by avoiding unnecessary copying.
