Rewritten for 4.07.

ghc/ANNOUNCE

-	     The Glasgow Haskell Compiler -- version 4.06
-	    ==============================================
-
-We are pleased to announce a new release of the Glasgow Haskell
-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 Haskell 98, agreed in December 1998.
-Haskell related information is available from the Haskell home page at
-
-	http://www.haskell.org/
-
-GHC's Web page lives at
-
-	http://www.haskell.org/ghc/
-
-+ What's new
-=============
-
-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".
-
-   - Clean up of concurrent I/O system; in particular, I/O is now non-blocking,
-     except (alas) on stdout/stderr for tiresome reasons.
-
-   - Some refinements to the exceptions mechanism:
-     http://www.haskell.org/ghc/docs/4.06/users_guide/release-4-06.html#exc-changes-406
-
-   - More performance tuning: compiled programs now allocate 10% less memory
-     than 4.04
-

-+ Mailing lists
-================
-
-We run mailing lists for GHC users and bug reports; to subscribe, send
-mail to majordomo@haskell.org; the msg body should be:
-
-    subscribe glasgow-haskell-<which> Your Name <your-email@where.you.are>
-
-Please send bug reports about GHC to glasgow-haskell-bugs@haskell.org ; GHC
-users hang out on glasgow-haskell-users@haskell.org
-
-
-+ On-line GHC-related resources
-================================
-
-Relevant URLs on the World-Wide Web:
-
-GHC home page    	  http://www.haskell.org/ghc/
-Haskell home page	  http://www.haskell.org/
-comp.lang.functional FAQ  http://www.cs.nott.ac.uk/Department/Staff/mpj/faq.html
-
-
-+ How to get it
-================
-
-The easy way is to go to the WWW page, which should be
-self-explanatory:
-
-	http://www.haskell.org/ghc/
-
-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 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:
-
-  * 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}
-  * {rs6000,powerpc}-ibm-aix
-
-The builder's guide included in distribution gives a complete
-run-down of what-ports-work; an on-line version can be found at
-

++ What's new
+=============
+
+This should be a stable release.  There have been many enhancements
+since 4.06, and shed-loads of bug-fixes (one shed (imperial) ~ one ton
+(US)).
+
+There are the following changes
+
+   - New profiling subsystem, based on cost-centre stacks.
+
+   - Working x86 native code generator: now it works properly, runs
+     about twice as fast as compiling via C, and is on a par for
+     run-time speed (except in FP-intensive programs).
+
+   - Implicit parameters (i.e. dynamic scoping without the pain).
+
+   - DEPRECATED pragma for marking obsolescent interfaces.
+
+   - In the wake of hslibs, a new package system for
+     libraries. -package should now be used instead of -syslib.
+
+   - Result type signatures work.
+
+   - Many tiresome long-standing bugs and problems (e.g. the trace
+     problem) have been fixed.
+
+   - Many error messages have been made more helpful and/or
+     accurate.
