We are pleased to announce a new release of the Glasgow Haskell
-Compiler (GHC), version 4.02. The source distribution is freely
-available via the World-Wide Web and through anon. FTP; details below.
+Compiler (GHC), version 4.08. The source distribution is freely
+available via the World-Wide Web and through anon. FTP, under a
+BSD-style license. See below for download details. Pre-built
+packages for Linux, FreeBSD, Solaris and Win32 are also available.
Haskell is "the" standard lazy functional programming language; the
current language version is Haskell 98, agreed in December 1998.
-Haskell related information is available from the Haskell home page at
- http://haskell.org/
+GHC is a state-of-the-art optimising compiler for Haskell, generating
+good code for a variety of platforms. 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, C++, whatever).
-GHC has a new Web page; point your browser at
+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 at

+ What's new
=============
-GHC 4.02 fixes several bugs in 4.01 and adds the following major features:
+This should be a stable release. There have been many enhancements
+since 4.06, and shed-loads of bug-fixes (one shed (imperial) ~ one ton
+(US)).
- * Full Haskell 98 language support,
+There are the following changes
- * Scoped type variables,
+ - New profiling subsystem, based on cost-centre stacks.
- * Better warnings for unused variables,
+ - Working x86 native code generator: now it works properly, runs
+ about twice as fast as compiling via C, and is on a par for
+ run-time speed (except in FP-intensive programs).
- * A new generational garbage collector.
+ - Implicit parameters (i.e. dynamic scoping without the pain).
-The following things have not been fixed yet:
+ - DEPRECATED pragma for marking obsolescent interfaces.
- * The native code generator is still flaky, and is turned off by
- default for the time being.
+ - In the wake of hslibs, a new package system for
+ libraries. -package should now be used instead of -syslib.
- * The profiler is still flaky.
+ - Result type signatures work.
-See the release notes for full details:
+ - Many tiresome long-standing bugs and problems (e.g. the trace
+ problem) have been fixed.
- http://research.microsoft.com/users/t-simonm/ghc/Docs/latest/users_guide/users_guide-1.html#ss1.4
+ - Many error messages have been made more helpful and/or
+ accurate.
-A source distribution and binaries for common architectures are
-available from the web page.
