- The Glasgow Haskell Compiler -- version 4.06

-We are pleased to announce a new release of the Glasgow Haskell
-Compiler (GHC), version 4.06. The source distribution is freely
-available via the World-Wide Web and through anon. FTP; details below.

+We are pleased to announce a new major release of the Glasgow Haskell
+Compiler (GHC), version 5.02. The source distribution is freely
+available via the World-Wide Web, 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.
-Haskell related information is available from the Haskell home page at
- http://www.haskell.org/
+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, C++, whatever).
+
+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
-=============
-This should be a stable release. We have not made major changes
-since 4.04 to the core compiler, but we have fixed lots of bugs.
-We believe that 4.06 is in a nice stable well-tested state. (Ha!)
+ What's new
+============
-Apart from that, there are the following changes
+5.02 incorporates many small refinements and bug fixes over the previous
+stable release (5.00.2). There are no major changes.
- - Major library reorganisation. All libraries, except the ones that
- are part of the Haskell 98 *language* specification, have moved to
- fptools/hslibs/. The hslibs tree is independent of GHC, shared between
- GHC, Hugs, and (we hope) other Haskell implementations.
- The idea is to make it easier for people to contribute and maintain
- libraries.
+ - 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.
- The hslibs/ tree is organised in a Java-like fashion. Details in
- the new Library guide:
- http://www.haskell.org/ghc/docs/4.06/hslibs/book1.html
+ - Several small changes to bring GHC into line with the newest Haskell 98
+ report.
- Existing programs that use the -syslib flag may need to change which
- syslibs they include.
+ - GHCi (the interactive system) now works on Windows.
- - Support for "foreign export dynamic".
+ - Partial FFI support in GHCi. At the moment, foreign import (both
+ static and dynamic) is supported on x86 and sparc platforms.
- - Clean up of concurrent I/O system; in particular, I/O is now non-blocking,
- except (alas) on stdout/stderr for tiresome reasons.
+ - A compacting garbage collector, to try and reduce space use.
- - Some refinements to the exceptions mechanism:
- http://www.haskell.org/ghc/docs/4.06/users_guide/release-notes-406.html#exc-changes-406
+ - Experimental: partial support for hierarchical module names.
- - More performance tuning: compiled programs now allocate 10% less memory
- than 4.04
+ - 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 ...)
