-XXX
+Added L<perlapi/sync_locale>.
+Changing the program's locale should be avoided by XS code. Nevertheless,
+certain non-Perl libraries called from XS, such as C<Gtk> do so. When this
+happens, Perl needs to be told that the locale has changed. Use this function
+to do so, before returning to Perl.
=back
=item *
-index() and rindex() no longer crash when used on strings over 2GB in
-size.
-L<[perl #121562]|https://rt.perl.org/Ticket/Display.html?id=121562>.
+Failing to compile C<use Foo> in an eval could leave a spurious
+C<BEGIN> subroutine definition, which would produce a "Subroutine
+BEGIN redefined" warning on the next use of C<use>, or other C<BEGIN>
+block. [perl #122107]
+
+=item *
+
+C<method { BLOCK } ARGS> syntax now correctly parses the arguments if they
+begin with an opening brace. [perl #46947]
