Subject: ANNOUNCE: GHC 5.03.20020204 snapshot release
> There have been a number of significant improvements made to GHC
> since the 5.02 sources were branched off the main GHC development
> tree, but we're not quite ready to make a full 5.04 release yet.
> However, we're keen to get feedback on the new features from people
> that don't have easy access to CVS or don't have the time & patience
> to build GHC from scratch, so we're making a snapshot release of the
> current GHC, in source and binary form.
> There are NO GUARANTEES as to the stability of this release, although
> we do know it has passed our basic three-stage bootstrap test and run
> the regression tests successfully. In some cases the documentation
> hasn't been fully updated to reflect the new features yet.
> Briefly, the changes relative to 5.02.2 are:
> - The type system now supports arbitrary rank polymorphism,
> given appropriate type annotations.
> - Heap profiling has had a major overhaul and now supports
> retainer profiling and biographical profiling ala nhc98.
> - Major improvements to the native code generators. You can now
> compile any and all code through them, including the Prelude.
> - The FFI syntax has been updated to match the latest version
> of the FFI Haskell 98 Addendum.
> - newtypes support deriving *any* class for which the
> underlying type is also an instance.
> - Linear implicit parameters: a highly experimental feature.
> - GHCi has several new commands:
> - ':show bindings' to list the bindings made on the command
> - ':show modules' to show which modules are loaded,
> - ':module' has been enhanced as per the discussion on the
> mailing list (syntax is still experimental - feedback
> - ':browse' similar to Hugs' :browse command.
> And many other minor changes & bugfixes.
> At the moment there is just the sources and a binary build for
> x86-linux available. We may add builds for other if they become
> You can get it from
> The GHC Development Team.
