=head1 Notice
[ List each enhancement as a =head2 entry ]

-
-This synyom is added for symmetry with the Unicode property names
-C<\p{Uppercase}> and C<\p{Lowercase}>.

=head1 Security
XXX Any security-related notices go here. In particular, any security
[ List each security issue as a =head2 entry ]
+=head2 User-defined regular expression properties
+
+Perl no longer allows a tainted regular expression to invoke a user-defined
+property via C<\p{...}> syntax. It simply dies instead [perl #82616].
+
=head1 Incompatible Changes
XXX For a release on a stable branch, this section aspires to be:
[ List each incompatible change as a =head2 entry ]
-=head2 Most C<\p{}> properties are now immune from case-insensitive matching
-
-For most Unicode properties, it doesn't make sense to have them match
-differently under C</i> case-insensitive matching than not. And doing
-so leads to unexpected results and potential security holes. For
-example
-
- m/\p{ASCII_Hex_Digit}+/i
+=head2 Passing references to warn()
-could previously match non-ASCII characters because of the Unicode
-matching rules. There were a number of bugs in this feature until an
-earlier release in the 5.13 series. Now this release reverts, and
-removes the feature completely except for the few properties where
-people have come to expect it, namely the ones where casing is an
-integral part of their functionality, such as C<m/\p{Uppercase}/i> and
-C<m/\p{Lowercase}/i>, both of which match the exact same code points,
-namely those matched by C<m/\p{Cased}/i>. Details are in
-L<perlrecharclass/Unicode Properties>.
+An earlier Perl 5.13.x release changed C<warn($ref)> to leave the reference
+unchanged, allowing C<$SIG{__WARN__}> handlers to access the original
+reference. But this stopped warnings that were references from having the
+file and line number appended even when there was no C<$SIG{__WARN__}>
+handler in place.
-User-defined property handlers that need to match differently under
-C</i> must change to read the new boolean parameter passed it which is
-non-zero if case-insensitive matching is in effect; 0 if not. See
-L<perluniprops/User-Defined Character Properties>.
+Now C<warn> checks for the presence of such a handler and, if there is
+none, proceeds to stringify the reference and append the file and line
+number. This allows simple uses of C<warn> for debugging to continue to
+work as they did before.

-A Unicode C<\p{}> property match in a regular rexpression pattern will
-now force Unicode rules for the rest of the regular expression
+A fix for a bug in C<length(undef)> in 5.13.4 introduced a regression that
+meant C<print length undef> did not warn when warnings were enabled. It now
+correctly warns [perl #85508].
+
+=item *
+
+The C<(?|...)> regular expression construct no longer crashes if the final
+branch has more sets of capturing parentheses than any other branch. This
+was fixed in Perl 5.10.1 for the case of a single branch, but that fix did
+not take multiple branches into account [perl #84746].
+
+=item *
+
+Accessing an element of a package array with a hard-coded number (as
+opposed to an arbitrary expression) would crash if the array did not exist.
+Usually the array would be autovivified during compilation, but typeglob
+manipulation could remove it, as in these two cases which used to crash:
+
+ *d = *a; print $d[0];
+ undef *d; print $d[0];

+C<#line> directives in string evals were not properly updating the arrays
+of lines of code (C<< @{"_<..."} >>) that the debugger (or any debugging or
