=============================================================
The (Interactive) Glasgow Haskell Compiler -- version 6.4.2
=============================================================
The GHC Team is pleased to announce a new patchlevel release of GHC.
This release contains a significant number of bugfixes relative to
6.4.1, so we recommend upgrading.
Highlights in this release:
- Cabal has been upgraded to version 1.1.4. While strictly speaking
this breaks our rules about not changing any library APIs in a
patchlevel release, it was felt that the Cabal shipped in 6.4.1
was lacking in various ways, and it was more important to provide a
Cabal that works with more existing packages. Some distributions
of GHC were already supplying an upgraded Cabal by default.
With the exception of Cabal, and OpenAL which was also upgraded, all
library APIs are identical to 6.4.1.

How to get it
~~~~~~~~~~~~~
The easy way is to go to the web page, which should be self-explanatory:
http://www.haskell.org/ghc/
We supply binary builds in the native package format for many
platforms, and the source distribution is available from the same
place.
Packages will appear as they are built - if the package for your
system isn't available yet, please try again later.
Background
~~~~~~~~~~
Haskell is a standard lazy functional programming language; the
current language version is Haskell 98, agreed in December 1998 and
revised December 2002.
GHC is a state-of-the-art programming suite for Haskell. Included is
an optimising compiler generating good code for a variety of
platforms, together with an interactive system for convenient, quick
development. The distribution includes space and time profiling
facilities, a large collection of libraries, and support for various
language extensions, including concurrency, exceptions, and foreign
language interfaces (C, whatever). GHC is distributed under a
BSD-style open source license.
A wide variety of Haskell related resources (tutorials, libraries,
specifications, documentation, compilers, interpreters, references,
contact information, links to research groups) are available from the
Haskell home page (see below).
