=head1 Notice
[ List each enhancement as a =head2 entry ]
-=head2 Unicode 9.0 is now supported
-
-A list of changes is at
-L<http://www.unicode.org/versions/Unicode9.0.0/>. Modules that are
-shipped with core Perl but not maintained by p5p do not necessarily
-support Unicode 9.0. L<Unicode::Normalize> does work on 9.0.
-
-=head2 Use of C<\p{I<script>}> uses the improved Script_Extensions
-property
-
-Unicode 6.0 introduced an improved form of the Script (C<sc>) property,
-and called it Script_Extensions (C<scx>). As of now, Perl uses this
-improved version when a property is specified as just C<\p{I<script>}>.
-The meaning of compound forms, like C<\p{sc=I<script>}> are unchanged.
-This should make programs be more accurate when determining if a
-character is used in a given script, but there is a slight chance of
-breakage for programs that very specifically needed the old behavior.
-See L<perlunicode/Scripts>.

-=head2 C<scalar(%hash)> return signature changed
-
-The value returned for C<scalar(%hash)> will no longer show information
-about the buckets allocated in the hash. It will simply return the count
-of used keys. It is thus equivalent to C<0+keys(%hash)>.
-
-A form of backwards compatibility is provided via C<Hash::Util::bucket_ratio()>
-which provides the same behavior as scalar(%hash) provided prior to
-Perl 5.25.

-An assertion failure with C<%: = 0> has been fixed. [perl #128238]
-
-=item *
-
-In Perl v5.18, the parsing of C<"$foo::$bar"> was accidentally changed,
-such that it would be treated as C<$foo."::".$bar>. The previous behavior,
-which was to parse it as C<$foo:: . $bar>, has been restored. [perl
-#128478]
-
-=item *
-
-Since Perl v5.20, line numbers have been off by one when perl is invoked
-with the B<-x> switch. This has been fixed. [perl #128508]
+Under C<use utf8>, the entire Perl program is now checked that the UTF-8
+is wellformed. This resolves [perl #126310].

XXX Add anything here that we forgot to add, or were mistaken about, in
the perldelta of a previous release.
