=head1 Notice
[ List each enhancement as a =head2 entry ]
+=head2 Perl now supports POSIX 2008 locale currency additions.
+
+On platforms that are able to handle POSIX.1-2008, the
+hash returned by
+L<C<POSIX::localeconv()>|perllocale/The localeconv function>
+includes the international currency fields added by that version of the
+POSIX standard. These are
+C<int_n_cs_precedes>,
+C<int_n_sep_by_space>,
+C<int_n_sign_posn>,
+C<int_p_cs_precedes>,
+C<int_p_sep_by_space>,
+and
+C<int_p_sign_posn>.

+Non-magical/non-tied scalars that contain only a floating point value and are

XXX
-=item *
-
-Compile-time checking of constant dereferencing (e.g.,
-C<< my_constant->() >>) has been removed, since it was not taking
-overloading into account. [perl #69456] [perl #122607]
-
-=item *
-
-Constant dereferencing now works correctly for typeglob constants.
-Previously the glob was stringified and its name looked up. Now the glob
-itself is used. [perl #69456]
-
-=item *
-
-When parsing a funny character ($ @ % &) followed by braces, the parser no
-longer tries to guess whether it is a block or a hash constructor (causing
-a syntax error when it guesses the latter), since it can only be a block.
-
-=item *
-
-C<undef $reference> now frees the referent immediately, instead of hanging
-on to it until the next statement. [perl #122556]
-
-=item *
-
-Various cases where the name of a sub is used (autoload, overloading, error
-messages) used to crash for lexical subs, but have been fixed.
-
-=item *
-
-Bareword lookup now tries to avoid vivifying packages if it turns out the
-bareword is not going to be a subroutine name.

+SVs of type SVt_NV are now bodyless when a build configure and platform allow
+it, specifically C<sizeof(NV) <= sizeof(IV)>. The bodyless trick is the same one
+as for IVs since 5.9.2, but for NVs, unlike IVs, is not guarenteed on all
+platforms and build configurations.
