We are pleased to announce a new release of the Glasgow Haskell
-Compiler (GHC), version 2.10. Source and Binary 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 1.4, agreed in April, 1997. Haskell
-related information is available from the Haskell home page at
+current language version is Haskell 98, agreed in December 1998.

+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).
+
+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
=============
-Release 2.10 is a full binary release (at least for the platforms we
-have access to, other builds are solicited). We hope this will be a
-solid release - barring any unforseen problems this should be the end
-of the 2.xx line.
+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)).
+
+There are the following changes
+
+ - New profiling subsystem, based on cost-centre stacks.
+
+ - 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).
+
+ - Implicit parameters (i.e. dynamic scoping without the pain).
+
+ - DEPRECATED pragma for marking obsolescent interfaces.
-Major new things in this release:
+ - In the wake of hslibs, a new package system for
+ libraries. -package should now be used instead of -syslib.
- * better -fwarn-overlapping-patterns checking,
- * lots of bug fixes.
+ - Result type signatures work.
-The next release will likely be GHC 3.00, containing mult-parameter
-type classes amongst other things. As of the next release, we will no
-longer support building with GHC 0.29.
+ - Many tiresome long-standing bugs and problems (e.g. the trace
+ problem) have been fixed.
-Merry Christmas and a Happy New Year from the GHC Team!
+ - Many error messages have been made more helpful and/or
+ accurate.

================
The easy way is to go to the WWW page, which should be
self-explanatory:

README file to find all of the documentation about this release. NB:
preserve modification times when un-tarring the files (no `m' option
for tar, please)!

+ System requirements
======================
-To compile up this source-only release, you need a machine with 16+MB
-memory, GNU C (`gcc'), `perl' plus a version of GHC installed (either
-version 0.29 or 2.02 onwards). We have seen GHC work on these platforms:
+To compile programs with GHC, you need a machine with 32+MB memory, GNU C
+and perl. This release is known to work on the following platforms:
- * alpha-dec-osf2
+ * i386-unknown-{linux,freebsd,netbsd,cygwin32,mingw32}
+ * sparc-sun-solaris2
* hppa1.1-hp-hpux{9,10}
- * sparc-sun-{sunos4,solaris2}
+
+Ports to the following platforms should be relatively easy (for a
+wunderhacker), but haven't been tested due to lack of time/hardware:
+
+ * i386-unknown-solaris2
+ * alpha-dec-osf{2,3}
* mips-sgi-irix{5,6}
- * i386-unknown-{linux,solaris2,freebsd,cygwin32}.
* {rs6000,powerpc}-ibm-aix
-Similar platforms should work with minimal hacking effort. The installer's
-guide included in distribution gives a complete run-down of what-ports-work;
