- The Glasgow Haskell Compiler -- version 2.04

==============================================
We are pleased to announce a new release of the Glasgow Haskell
-Compiler (GHC), version 2.04. Source distribution is freely available

+available via the World-Wide Web and through anon. FTP; details below.
Haskell is "the" standard lazy functional programming language; the
current language version is 1.4, agreed in April, 1997. Haskell

+ What's new
=============
-Release 2.04 represent work done through May '97; highlights include:
-
- * Data constructors can now have polymophic fields, and ordinary
- functions can have polymoprhic arguments. Details on
-
- http://www.cse.ogi.edu/~simonpj/quantification.html
-
- Existential types coming, but not done yet.
-
- * Pattern guards implemented, see
-
- http://www.cse.ogi.edu/~simonpj/guards.html
-
- * Compiler can now compile itself (i.e., no real dependence on
- the Haskell 1.2 compiler anymore (version 0.29)).
+GHC 3.00 is a source-only release. There are no binaries available at
+the current time: in the interests of spending more time hacking and
+less time building distributions, we're shoving this one out as
+quickly as possible so that intrepid hackers can try it out.
- * Faster compilation
- Compilation speeds has improved since 2.02, although it still slower
- than GHC-0.29, the Good Old Compiler. (the gap is narrowing, though!)
-
- * Code quality is better, the simplifier and inlining machinery has been
- refurbished. Not sure how much better.
-
- * powerpc-ibm-aix is now a supported GHC platform, due to the
- Heroic Efforts of Andr\'e Santos <alms@di.ufpe.br>.
-
- * It has been tested against a large suite of (mostly) Haskell 1.2
- programs (the NoFib suite). Bunch of bugs related to new
- Haskell 1.4 has been weeded out.
-
- * A couple of Haskell 1.4 features are still incompletely supported,
- notably polymorphic strictness annotations, and Unicode.
-
-Please see the release notes for a complete discussion of What's New.
+Important new features:
+ * Multi-parameter type classes. Please try 'em out; we'd
+ appreciate the feedback.

Once you have the distribution, please follow the pointers in the
README file to find all of the documentation about this release. NB:
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 2.02/2.03). We have seen GHC work on these platforms:
+version 0.29 or 2.10 onwards). We have seen GHC work on these platforms:
- * alpha-dec-osf2
+ * alpha-dec-osf{2,3}
* hppa1.1-hp-hpux{9,10}
* sparc-sun-{sunos4,solaris2}
* mips-sgi-irix{5,6}
* i386-unknown-{linux,solaris2,freebsd,cygwin32}.
- * powerpc-ibm-aix
+ * {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.
