available.
-The syntaxes C<@a->[...]> and C<@h->{...}> have now been deprecated.
+The syntaxes C<< @a->[...] >> and C<< @h->{...} >> have now been deprecated.
The suidperl is also considered to be too much a risk to continue
maintaining and the suidperl code is likely to be removed in a future
implementation even less so. If you have used that feature to
disallow all but fully qualified variables, C<use strict;> instead.
+The chdir(undef) and chdir('') behaviors to match chdir() has been
+deprecated. In future versions, chdir(undef) and chdir('') will
+simply fail.

=head1 Core Enhancements
In general a lot of fixing has happened in the area of Perl's
VMS now works under PerlIO.

+
+END blocks are now run even if you exit/die in a BEGIN block.
+The execution of END blocks is now controlled by
+PL_exit_flags & PERL_EXIT_DESTRUCT_END. This enables the new
+behaviour for perl embedders. This will default in 5.10. See
+L<perlembed>.

relate to the changed IO model of Perl.) See L<perlmacos>.
