Bug fixes and minor enhancements have been applied to B::Deparse,

-Text::Wrap, UNIVERSAL.

=head1 Utility Changes
map() that changes the size of the list should now work faster.
+=item *
+
+sort() has been changed to use mergesort internally as opposed to the
+earlier quicksort. For very small lists this may result in slightly
+slower sorting times, but in general the speedup should be at least 20%.
+Additional bonuses are that the worst case behaviour of sort() is now
+better (in computer science terms it now runs in time O(N log N), as
+opposed to quicksorts Theta(N**2) worst-case run time behaviour), and
+that sort() is now stable (meaning that elements with identical keys
+will stay ordered as they were before the sort).

+The experimental long double support is still very much so in Solaris.
+(Other platforms like Linux and Tru64 are beginning to solidify in

-=item In string, @%s now must be written as \@%s
+=item *
+
+Many Storable tests fail on AIX configured with 64 bit integers.
-(F) It used to be that Perl would try to guess whether you wanted an
-array interpolated or a literal @. It did this when the string was
-first used at runtime. Now strings are parsed at compile time, and
-ambiguous instances of @ must be disambiguated, either by prepending a
-backslash to indicate a literal, or by declaring (or using) the array
-within the program before the string (lexically). (I<Someday it will
-simply assume that an unbackslashed @ interpolates an array.>)
+So far unidentified problems break Storable in AIX if Perl is
+configured to use 64 bit integers. AIX in 32-bit mode works and
+other 64-bit platforms work with Storable.
