The (Interactive) Glasgow Haskell Compiler -- version 5.02
============================================================
We are pleased to announce a new major release of the Glasgow Haskell
Compiler (GHC), version 5.00. 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 a standard lazy functional programming language; the
current language version is Haskell 98, agreed in December 1998.

What's new
============
5.00 has been majorly revamped since the previous stable version, 4.08.2.
This should be a stable release. Major changes since 4.08.2 are:
5.02 incorporates many small refinements and bug fixes over the previous
stable release (5.00.2). There are no major changes.
- An interactive system, similar in style to Hugs. You can interactively
load and unload modules, run expressions, ask the types of things.
Module dependencies are tracked and chased automatically.
Combinations of compiled and interpreted modules may be used.
All the GHC libraries are available in interactive mode, as are
most of the Glasgow extensions to Haskell 98. Compilation in
interactive mode (to bytecode) is about three times faster than
compiling to object code.
- Much improved support for Windows platforms. Binary builds are
now entirely freestanding. There's no need to install Cygwin or
Mingwin to use it. It's a one-click-install-and-off-you-go story now.
- Batch compilation of multiple modules at once, with automatic
dependency chasing. For large programs this can halve compilation
times, and removes the need for Makefiles.
- Several small changes to bring GHC into line with the newest Haskell 98
report.
- Enhanced package (library) management system. Packages may be
installed and removed from an installation using the ghc-pkg tool.
- GHCi (the interactive system) now works on Windows.
- Initial Unicode support - the Char type is now 31 bits.
- Partial FFI support in GHCi. At the moment, foreign import (both
static and dynamic) is supported on x86 and sparc platforms.
- Sparc native code generator, giving much faster compilation on sparcs.
(Native code generation for x86s has been available for a while).
- A compacting garbage collector, to try and reduce space use.
- Improved heap profiling - you can restrict heap profiles
by type, closure description, cost centre, and module.
- Experimental: partial support for hierarchical module names.
- Support for the latest Foreign Function Interface (FFI)
proposals. Marcin Kowalczyk's hsc2hs tool is included.
- Experimental: following heroic hacking by Ken Shan, 5.02 now
works on Alpha (Tru64 only). Many 64-bit bugs have been shaken
out. At the moment only the batch-mode compiler works -- no GHCi
or native code generator yet.
- Language extensions: parallel list comprehensions and functional
dependencies.
- The usual huge collection of bug fixes. Most reported bugs have
been fixed.
We've found and fixed more bugs than you could possibly imagine. A
big thank-you to all those who reported bugs in the 5.00.X series. We
claim to have fixed almost all reported bugs. In general we've spent
a large amount of effort trying to improve the stability of the
system relative to 5.00.X. (Famous last words ...)
