Announce for 5.04

The (Interactive) Glasgow Haskell Compiler -- version 5.02
The (Interactive) Glasgow Haskell Compiler -- version 5.04
We are pleased to announce a new major release of the Glasgow Haskell
Compiler (GHC), version 5.02.
Compiler (GHC), version 5.04.
This is the first version of GHC that has all of the following:
Highlights include:
* An interactive read-eval-print loop, similar to Hugs.
You can load a mixture of compiled and interpreted modules;
in particular, you automatically use the precompiled libraries,
so your "interpreted" programs often run pretty fast.
* Hierarchical libraries, with documentation produced by Haddock.
* Works solidly on Windows platforms. Installation is simple
(Installshield); you don't have to install anything else;
and GHC does not get confused if you also happen to
have (say) Cygwin installed.
* New type system extensions: full rank-N types and kind
* New heap profiling facilities (retainer profiling, biographical
* Implements the changes adopted for the (now almost finalised)
Revised Haskell 98 Language and Library Reports.
* MacOS X support
* The ability to emit "External Core", a documented typed
intermediate language, suitable for slurping up into other
tools. [Andrew Tolmach's work.]
See the release notes for a full list of the changes:
* A particularly thorough pre-release test programme.
Some releases are more solid than others; this one is
at the solid end of the spectrum. We fondly hope.
So if you have been waiting to upgrade your GHC 4.08, this is
the moment.

More details about what's new
5.02 incorporates many small refinements and bug fixes over the previous
stable release (5.00.2). There are no major language changes.
- Implements Haskell 98 (revised)
- Ability to emit External Core. (But GhC can't read External Core
back in. Yet.)
- 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.
- Several small changes to bring GHC into line with the newest Haskell 98
- GHCi (the interactive system) now works on Windows.
- Partial FFI support in GHCi. At the moment, foreign import (both
static and dynamic) is supported on x86 and sparc platforms.
- A compacting garbage collector, to try and reduce space use.
- Ability to disconnect built-in numeric syntax from the supplied
Prelude. This allows you to define your own arithmetic packages,
which Haskell98 doesn't quite support.
- Experimental: partial support for hierarchical module names.
- 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.
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 ...)
