The Glasgow Haskell Compiler -- version 3.00

We are pleased to announce a new release of the Glasgow Haskell
Compiler (GHC), version 3.00.  The source distribution is freely
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
related information is available from the Haskell home page at

+ What's new

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.

Important new features:

   * Multi-parameter type classes.  Please try 'em out; we'd
     appreciate the feedback.

   * GHC 2.10 is required to build it.  We've removed all the old
     Haskell 1.2 backwards-compatibility stuff.

   * Lots of bugs fixed.

As usual check the release notes for the full story.

+ Mailing lists

We run mailing lists for GHC users and bug reports; to subscribe, send
mail to [EMAIL PROTECTED]; the msg body should be:

Please send bug reports about GHC to [EMAIL PROTECTED] ; GHC
users hang out on [EMAIL PROTECTED]

Once you have the distribution, please follow the pointers in the
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 2.10 onwards). We have seen GHC work on these platforms:

  * 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}.
  * {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;
