OSCON Haskell Tutorial. Simon Peyton-Jones Appeared at the O'Reilly Open Source Convention (OSCON) in Portland, delivering a range of talks, including A Taste of Haskell, A Keynote on Functional Languages, Nested Data Parallelism and Transactional Memory for Concurrent Programming. Videos are available for most of these talks: A Taste of Haskell: Part 1, A Taste of Haskell: Part 2, slides for A Taste of Haskell, Transactional Memory for Concurrent Programming and the NDP talk at the London Hugs meeting.
hpodder 1.0. John Goerzen announced version 1.0.0 of hpodder, the command-line podcatcher (podcast downloader) that just happens to be written in everyone's favorite language. You can get it here. Version 1.0.0 sports a new mechanism for detecting and disabling feeds or episodes that repeatedly result in errors, updates to the Sqlite database schema, and several bugfixes.
encoding-0.1. Henning Gnther announced the release of 'encoding', a Haskell library to cope with many character encodings found on modern computers. At the moment it supports (much more is planned): ASCII, UTF-8, -16, -32, ISO 8859-* (alias latin-*), CP125* (windows codepages), KOI8-R, Bootstring (base for punycode)
Dimensional 0.6: Statically checked physical dimensions. Bjrn Buckwalter announced a library providing data types for performing arithmetic with physical quantities and units. Information about the physical dimensions of the quantities/units is embedded in their types and the validity of operations is verified by the type checker at compile time. The boxing and unboxing of numerical values as quantities is done by multiplication and division with units.

Learn Haskell in 10 minutes. Chris Smith prepared a new tutorial on the basics of Haskell
Haskell Program Coverage 0.4. Andy Gill announced release 0.4 of Hpc, a tool for Haskell developers. Hpc is a tool-kit to record and display Haskell Program Coverage. Hpc includes tools that instrument Haskell programs to record program coverage, run instrumented programs, and display the coverage information obtained.
Uniplate 1.0. Neil Mitchell announced Uniplate (formerly known as Play), a library for boilerplate removal requiring only Haskell 98 (for normal use) and optionally multi-parameter type classes (for more advanced features).
Atom: Hardware description in Haskell. Tom Hawkins announced Atom, a high-level hardware description language embedded in Haskell that compiles conditional term rewriting systems into conventional HDL.
Catch. Neil Mitchell announced a pattern-match checker for Haskell, named Catch. Do you sometimes encounter the dreaded 'pattern match failure: head' message? Do you have incomplete patterns which sometimes fail? Do you have incomplete patterns which you know don't fail, but still get compiler warnings about them? Would you like to statically ensure the absence of all calls to error? This is what Catch helps ... catch!
Asterisk Gateway Interface. Jeremy Shaw uploaded a simple AGI interface to hackage. For more about Asterix, see here.
Yaml Reference. Gaal Yahas announced a Haskell (Cabal) package containing the YAML spec productions wrapped in Haskell magic to convert them to an executable parser. The parser is streaming. It isn't intended to serve as a basis for a YAML tool chain; instead it is meant to serve as a reference implementation of the spec.
