+ The (Interactive) Glasgow Haskell Compiler -- version 5.04
============================================================
We are pleased to announce a new major release of the Glasgow Haskell
-Compiler (GHC), version 5.00. 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 a standard lazy functional programming language; the
-current language version is Haskell 98, agreed in December 1998.
-
-GHC is a state-of-the-art programming suite for Haskell. Included is
-an optimising compiler generating good code for a variety of
-platforms, together with an interactive system for convenient, quick
-development. 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

- What's new
-============
-
-5.00 has been majorly revamped since the previous stable version, 4.08.2.
-This should be a stable release. Major changes since 4.08.2 are:
-
- - An interactive system, similar in style to Hugs. You can interactively
- load and unload modules, run expressions, ask the types of things.
- Module dependencies are tracked and chased automatically.
- Combinations of compiled and interpreted modules may be used.
- All the GHC libraries are available in interactive mode, as are
- most of the Glasgow extensions to Haskell 98. Compilation in
- interactive mode (to bytecode) is about three times faster than
- compiling to object code.
+Compiler (GHC), version 5.04.
- - Batch compilation of multiple modules at once, with automatic
- dependency chasing. For large programs this can halve compilation
- times, and removes the need for Makefiles.
+Highlights include:
- - Enhanced package (library) management system. Packages may be
- installed and removed from an installation using the ghc-pkg tool.
+ * Hierarchical libraries, with documentation produced by Haddock.
- - Initial Unicode support - the Char type is now 31 bits.
+ * New type system extensions: full rank-N types and kind
+ annotations.
+
+ * New heap profiling facilities (retainer profiling, biographical
+ profiling).
- - Sparc native code generator, giving much faster compilation on sparcs.
- (Native code generation for x86s has been available for a while).
+ * MacOS X support
- - Improved heap profiling - you can restrict heap profiles
- by type, closure description, cost centre, and module.
+See the release notes for a full list of the changes:
- - Support for the latest Foreign Function Interface (FFI)
- proposals. Marcin Kowalczyk's hsc2hs tool is included.
+ http://www.haskell.org/ghc/docs/latest/html/users_guide/release-5-04.html
- - Language extensions: parallel list comprehensions and functional
- dependencies.
- - The usual huge collection of bug fixes. Most reported bugs have
- been fixed.

and perl. This release is known to work on the following platforms:
- * i386-unknown-{linux,freebsd,mingw32}
+ * i386-unknown-{linux,*bsd,mingw32}
* sparc-sun-solaris2
+ * alpha-dec-osf3
+ * powerpc-apple-darwin (MacOS/X)
Ports to the following platforms should be relatively easy (for a
wunderhacker), but haven't been tested due to lack of time/hardware:
* hppa1.1-hp-hpux{9,10}
* i386-unknown-solaris2
- * alpha-dec-osf{2,3}
* mips-sgi-irix{5,6}
* {rs6000,powerpc}-ibm-aix
