+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.
