=head1 DESCRIPTION
This document describes differences between the 5.15.0 release and
the 5.14.0 release.
-If you are upgrading from an earlier release such as 5.YYY.YYY, first read
-L<perl5YYYdelta>, which describes differences between 5.ZZZ.ZZZ and
-5.YYY.YYY.
+If you are upgrading from an earlier release such as 5.12.0, first read
+L<perl5140delta>, which describes differences between 5.12.0 and
+5.14.0.
Some of the changes have been included in Perl 5.14.1. These are
indicated with a "(5.14.1)" marker.

+Perl skips copying values returned from a subroutine if it thinks the value
+is not in use elsewhere. Due to faulty logic, this would happen with the
+result of C<delete>, C<shift> or C<splice>, even if the result was
+referenced elsewhere. So C<< \sub { delete $_[0] }->($x) >> would return a
+reference to C<$x>. This has been fixed [perl #91844].
