=head1 Notice
[ List each enhancement as a =head2 entry ]
-=head2 Wildcards in Unicode property value specifications are now
-partially supported
-
-You can now do something like this in a regular expression pattern
-
- qr! \p{nv= /(?x) \A [0-5] \z / }!
-
-which matches all Unicode code points which have numeric value is
-between 0 and 5 inclusive.
-
-This marks another step in implementing the regular expression features
-the Unicode Consortium suggests.
-
-Most properties are supported, with the remainder planned for 5.32.
-Details are in L<perlunicode/Wildcards in Property Values>.
-
-=head2 Unicode 12.0 is supported
-
-For details, see L<https://www.unicode.org/versions/Unicode12.0.0/>.
-
-Because of a change in Unicode release cycles, Perl jumps from Unicode
-10.0 in Perl 5.28 to Unicode 12.0 in Perl 5.30.
-
-=head2 It is now possible to compile perl to always use thread-safe
-locale operations.
-
-Previously, these calls were only used when the perl was compiled to be
-multi-threaded. To always enable them, add
-
- -Accflags='-DUSE_THREAD_SAFE_LOCALE'
-
-to your F<Configure> flags.
