- The Glasgow Haskell Compiler -- version 2.10
+ The Glasgow Haskell Compiler -- version 4.06
==============================================
We are pleased to announce a new release of the Glasgow Haskell
-Compiler (GHC), version 2.10. Source and Binary distribution is freely
+Compiler (GHC), version 4.06. 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
+current language version is Haskell 98, agreed in December 1998.

+ What's new
=============
-Release 2.10 is a full binary release (at least for the platforms we
-have access to, other builds are solicited). We hope this will be a
-solid release - barring any unforseen problems this should be the end
-of the 2.xx line.
+This should be a stable release. We have not made major changes
+since 4.04 to the core compiler, but we have fixed lots of bugs.
+We believe that 4.06 is in a nice stable well-tested state. (Ha!)
+
+Apart from that, there are the following changes
+
+ - Major library reorganisation. All libraries, except the ones that
+ are part of the Haskell 98 *language* specification, have moved to
+ fptools/hslibs/. The hslibs tree is independent of GHC, shared between
+ GHC, Hugs, and (we hope) other Haskell implementations.
+ The idea is to make it easier for people to contribute and maintain
+ libraries.
+
+ The hslibs/ tree is organised in a Java-like fashion. Details in
+ the new Library guide:
+ http://www.haskell.org/ghc/docs/4.06/hslibs/book1.html
+
+ Existing programs that use the -syslib flag may need to change which
+ syslibs they include.
+
+ - Support for "foreign export dynamic".
-Major new things in this release:
+ - Clean up of concurrent I/O system; in particular, I/O is now non-blocking,
+ except (alas) on stdout/stderr for tiresome reasons.
- * better -fwarn-overlapping-patterns checking,
- * Happy is no longer included in binary distributions:
- we're making separate Happy binaries, see
- ftp://ftp.dcs.gla.ac.uk/pub/haskell/happy
- * lots of bug fixes.
+ - Some refinements to the exceptions mechanism:
+ http://www.haskell.org/ghc/docs/4.06/users_guide/release-4-06.html#exc-changes-406
-The next release will likely be GHC 3.00, containing mult-parameter
-type classes amongst other things. As of the next release, we will no
-longer support building with GHC 0.29.
+ - More performance tuning: compiled programs now allocate 10% less memory
+ than 4.04
-Merry Christmas and a Happy New Year from the GHC Team!

+ 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 2.02 onwards). We have seen GHC work on these platforms:
+To compile up this source-only release, you need a machine with 32+MB
+memory, GNU C (`gcc'), `perl' plus a version of GHC installed (3.02 at
+least). This release is known to work on the following platforms:
- * alpha-dec-osf2
- * hppa1.1-hp-hpux{9,10}
+ * i386-unknown-{linux,solaris2,freebsd,netbsd,cygwin32}
* sparc-sun-{sunos4,solaris2}
+ * hppa1.1-hp-hpux{9,10}
+
+Ports to the following platforms should be relatively easy, but
+haven't been tested due to lack of time/hardware:
+
+ * alpha-dec-osf{2,3}
* 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
