"ndp-0.1: nested data parallelism in Haskell"
"Roman Leshchinskiy"
"[http://article.gmane.org/gmane.comp.lang.haskell.general/15006 announced] the first release of [http://haskell.org/haskellwiki/GHC/Data_Parallel_Haskell the NDP package], a library for writing nested data-parallel programs in Haskell, on shared-memory multiprocessors. The NDP library is part of the Data Parallel Haskell project. The paper [http://www.cse.unsw.edu.au/~chak/papers/CLPKM07.html Data Parallel Haskell: a status report] describes the underlying design and go through an example program.",

Item
"binary 0.3: bigger, better, faster"
"Lennart Kolmodin"
"[http://article.gmane.org/gmane.comp.lang.haskell.general/15044 announced] binary 0.3. The 'binary' package provides efficient serialization of Haskell values to and from lazy ByteStrings. ByteStrings constructed this way may then be written to disk, written to the network, or further processed (e.g.  stored in memory directly, or compressed in memory with zlib or bzlib). It's available [http://hackage.haskell.org/packages/archive/binary/binary-0.3.tar.gz through Hackage], or via its [http://www.cse.unsw.edu.au/~dons/binary.html homepage].",

Item
"Text.HTML.Chunks"
"Matthew Sackman"
"[http://article.gmane.org/gmane.comp.lang.haskell.general/15028 announced] the [http://www.wellquite.org/chunks Text.HTML.Chunks] library, a clone with improvements of the Perl HTML::Chunks module. The main achievement is the use of template-haskell to combine the template into the code at compile time. This then allows for static checking that the variables/fields that the templates are expecting are indeed being provided and that the templates the code is trying to use do indeed exist. The template is then incorporated within the code, removing the dependency on the template.",

Item
"Phooey 1.0 and GuiTV 0.3"
"Conal Elliott"
"[http://article.gmane.org/gmane.comp.lang.haskell.general/15047 announced] a new version of Phooey, a library for functional user interfaces.  Highlights in this release: uses new TypeCompose package, which includes a simple implementation of data-driven computation; new Applicative functor interface; eliminated the catch-all Phooey.hs module. Now import any one of Graphics.UI.Phooey.{Monad ,Applicative,Arrow}; Phooey.Monad has two different styles of output widgets, made by owidget and owidget' and more. Phooey is also used in GuiTV, a library for composable interfaces and 'tangible values'." ,

Item
"The real Monad Transformer"
"Henning Thielemann"
"[http://article.gmane.org/gmane.comp.lang.haskell.general/15059 announced] the real monad transformer! It has been argued that people avoid Haskell because of terms from Category theory like 'Monad'. This problem can now be solved by a wrapper which presents all the internet entirely without monads! Start [http://tinyurl.com/2e32r4 the parallel Haskell wiki]. Of course the tool is written in Haskell, that is, Haskell helps solving problems which only exist because of Haskell. Bug reports and feature requests can be tracked at [https://sourceforge.net/projects/parallelweb here].",

Item
"GHC 6.6.1 Release Candidate"
"Ian Lynagh"
"[http://article.gmane.org/gmane.comp.lang.haskell.glasgow.user/11964 announced] the Release Candidate phase for GHC 6.6.1. Snapshots beginning with 6.6.20070409 are release candidates for 6.6.1. You can download snapshots from [http://www.haskell.org/ghc/dist/stable/dist/ here].",

Item
"Haskell Cryptographic Library 4.0.3"
"Dominic Steinitz"
"[http://article.gmane.org/gmane.comp.lang.haskell.libraries/6761 announced] the release of a new version of the Haskell Cryptographic Library based on the [http://www.haskell.org/haskellwiki/Crypto_Library_Proposal crypto proposal].  See [http://www.haskell.org/crypto/ the crypto home] for more details. There is now no dependency on NewBinary. The downside is the library contains no support for ASN.1 which will be released in separate package.",

Item
"TagSoup library 0.1"
"Neil Mitchell"
"[http://article.gmane.org/gmane.comp.lang.haskell.general/15100 announced] TagSoup, a library for extracting information out of unstructured HTML code, sometimes known as [http://www-users.cs.york.ac.uk/~ndm/tagsoup/ tag-soup]. The HTML does not have to be well formed, or render properly within any particular framework. This library is for situations where the author of the HTML is not cooperating with the person trying to extract the information, but is also not trying to hide the information.  The library provides a basic data type for a list of unstructured tags, a parser to convert HTML into this tag type, and useful functions and combinators for finding and extracting information.",

Item
"ParseP library 0.1"
"Twan van Laarhoven"
"[http://article.gmane.org/gmane.comp.lang.haskell.general/15101 announced] a generalized/improved variant of the ReadP parser library. Unlike ReadP ParseP can handle any type of token, and actually generates error messages in case something goes wrong. It is also possible to use things other then a list as an input stream, for example ByteStrings.",

Item
"Debian library for Haskell"
"Jeremy Shaw"
"[http://article.gmane.org/gmane.comp.lang.haskell.general/15064 announced] the availability of a library for interacting with the Debian system from Haskell. This library does not (currently) depend on dpkg or apt for any functionality. Contributions are welcome, and the library is available from [http://hackage.haskell.org/cgi-bin/hackage-scripts/package/debian-1.2 Hackage].
Well-Support Modules: parsing/Printing Debian control files, parsing/printing sources.list files, comparing Debian version numbers, a data type for encoding Debian relations and more.",

Item
"System.FilePath 1.0"
"Neil Mitchell"
"[http://article.gmane.org/gmane.comp.lang.haskell.general/15097 announced] the [http://www-users.cs.york.ac.uk/~ndm/filepath/ System.FilePath] 1.0 release!
