+=head1 NAME
+
+perl5163delta - what is new for perl v5.16.3
+
+=head1 DESCRIPTION
+
+This document describes differences between the 5.16.2 release and
+the 5.16.3 release.
+
+If you are upgrading from an earlier release such as 5.16.1, first read
+L<perl5162delta>, which describes differences between 5.16.1 and
+5.16.2.
+
+=head1 Core Enhancements
+
+No changes since 5.16.0.
+
+=head1 Security
+
+This release contains one major and a number of minor security fixes.
+These latter are included mainly to allow the test suite to pass cleanly
+with the clang compiler's address sanitizer facility.
+
+=head2 CVE-2013-1667: memory exhaustion with arbitrary hash keys
+
+With a carefully crafted set of hash keys (for example arguments on a
+URL), it is possible to cause a hash to consume a large amount of memory
+and CPU, and thus possibly to achieve a Denial-of-Service.
+
+This problem has been fixed.
+
+=head2 wrap-around with IO on long strings
+
+Reading or writing strings greater than 2**31 bytes in size could segfault
+due to integer wraparound.
+
+This problem has been fixed.
+
+=head2 memory leak in Encode
+
+The UTF-8 encoding implementation in Encode.xs had a memory leak which has been
+fixed.
+
+=head1 Incompatible Changes
+
+There are no changes intentionally incompatible with 5.16.0. If any
+exist, they are bugs and reports are welcome.
+
+=head1 Deprecations
+
+There have been no deprecations since 5.16.0.

+=head1 Acknowledgements
+
+Perl 5.16.3 represents approximately 4 months of development since Perl 5.16.2
+and contains approximately 870 lines of changes across 39 files from 7 authors.
+
+Perl continues to flourish into its third decade thanks to a vibrant community
+of users and developers. The following people are known to have contributed the
+improvements that became Perl 5.16.3:
+
+Andy Dougherty, Chris 'BinGOs' Williams, Dave Rolsky, David Mitchell, Michael
+Schroeder, Ricardo Signes, Yves Orton.
+
+The list above is almost certainly incomplete as it is automatically generated
+from version control history. In particular, it does not include the names of
+the (very much appreciated) contributors who reported issues to the Perl bug
+tracker.
+
+For a more complete list of all of Perl's historical contributors, please see
+the F<AUTHORS> file in the Perl source distribution.
+
+=head1 Reporting Bugs
+
+If you find what you think is a bug, you might check the articles
+recently posted to the comp.lang.perl.misc newsgroup and the perl
+bug database at http://rt.perl.org/perlbug/ . There may also be
+information at http://www.perl.org/ , the Perl Home Page.
+
+If you believe you have an unreported bug, please run the L<perlbug>
+program included with your release. Be sure to trim your bug down
+to a tiny but sufficient test case. Your bug report, along with the
+output of C<perl -V>, will be sent off to perlbug@perl.org to be
+analysed by the Perl porting team.
+
+If the bug you are reporting has security implications, which make it
+inappropriate to send to a publicly archived mailing list, then please
+send it to perl5-security-report@perl.org. This points to a closed
+subscription unarchived mailing list, which includes all the core
+committers, who will be able to help assess the impact of issues, figure
+out a resolution, and help co-ordinate the release of patches to
+mitigate or fix the problem across all platforms on which Perl is
+supported. Please only use this address for security issues in the Perl
+core, not for modules independently distributed on CPAN.
