We are pleased to announce a new release of the Glasgow Haskell

+Compiler (GHC), version 4.08. 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
+ What's new
=============
- - GHC is now officially Open Source, see the LICENSE file in the
- distribution for details.
+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)).
- - Rewrite rules can be specified in the source using the RULES
- pragma. This is used for automatic fusion of common list functions.
+There are the following changes
- - Performance tuning: compiled programs now allocate 30% less
- and run 20% faster on average compared to GHC 4.02.
+ - New profiling subsystem, based on cost-centre stacks.
- - GHC now uses a Happy parser instead of the old yacc/lex one.
+ - 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.
