We are pleased to announce the first release of the Glasgow Haskell
Compiler (GHC, version 2.02) for *Haskell 1.4*. Sources and binaries

-GHC 2.02 is a beta-quality release:
+GHC 2.02 is a beta-quality release - some highlights:
* It is reliable.
- It has been extensively tested against a large suite of Haskell 1.2
- programs, but not so extensively tested against Haskell 1.4 programs
- because we don't have a comprehensive set (Donations of Haskell 1.4
- programs to our test suite are most welcome).

+ programs to our test suite are most welcome).
* It should generate good code.
- All the optimisations that GHC 0.29 used to do are back in, with
- the exception of specialisation. It ought to be the case that
- GHC 2.02 outperforms GHC 0.29, because it has a much better
- handle on cross-module inlining, but there's a good chance that
- there are performance "holes" lurking. We have yet to make
- a systematic comparison. (Please send us programs where 2.02
- does noticeably worse than 0.29.)

* It is more expensive than it should be.
- GHC 2.02 has received even less attention to its own performance.
- At present it eats more space and time than GHC 0.29, especially
- for very small programs. We'll work on this.

your arguments to and from C.

mentions a function or type that is not itself exported. This is
one place Haskell 1.4's new module system really pays off.

sparc-sun-{sunos4,solaris2}, mips-sgi-irix5, and

Binaries are distributed in `bundles', e.g. a "profiling bundle" or a
"concurrency bundle" for your platform. Just grab the ones you need.
