 C<_> is now forced to be a bareword after a filetest operator. This solves
 a number of misparsing issues when a global C<_> subroutine is defined.
 
+=head2 C<mkdir()>
+
+C<mkdir()> without arguments now defaults to C<$_>.
+
+=head2 Magic goto and eval
+
+The construct C<eval { goto &foo }> is now disallowed. (Note that the
+similar construct, but with C<eval("")> instead, was already forbidden.)
+
+=head2 C<$#> has been removed
+
+The deprecated C<$#> variable (output format for numbers) has been
+removed. A new warning, C<$# is no longer supported>, has been added.
+
+=head2 C<:unique>
+
+The C<:unique> attribute has been made a now-op, since its current
+implementation was fundamentally flawed and not threadsafe.

+=head2 C<say()>
+
+=head2 C<CLONE_SKIP()>
+
+Perl has now support for the C<CLONE_SKIP> special subroutine. Like
+C<CLONE>, C<CLONE_SKIP> is called once per package; however, it is called
+just before cloning starts, and in the context of the parent thread. If it
+returns a true value, then no objects of that class will be cloned. See
+L<perlmod> for details.
+
+=head2 C<${^CHILD_ERROR_NATIVE}>
+
+A new internal variable, C<${^CHILD_ERROR_NATIVE}>, gives the native
+status returned by the last pipe close, backtick command, successful call
+to wait() or waitpid(), or from the system() operator. See L<perlrun> for
+details.
+
+=head2 Assertions
+
+The support for assertions, introduced in perl 5.9.0, has been improved.
+The syntax for the C<-A> command-line switch has changed; it now accepts
+an optional module name, defaulting to C<assertions::activate>. See
+L<assertions> and L<perlrun>.
+
+=head2 Unicode Character Database 4.1.0
+
+The copy of the Unicode Character Database included in Perl 5.9 has
+been updated to 4.1.0.

 =head1 New or Changed Diagnostics
 
+=head2 Attempt to set length of freed array

+This is a new warning, produced in situations like the following one:

+    $$r = 503;
+
+=head2 Search pattern not terminated or ternary operator parsed as search pattern
+
+This syntax error indicates that the lexer couldn't find the final
+delimiter of a C<?PATTERN?> construct. Mentioning the ternary operator in
+this error message makes syntax diagnostic easier.
