+L<perl5161delta>, which describes differences between 5.16.0 and
+5.16.1.
+

+
+There are no changes intentionally incompatible with 5.16.0

+
+Perl 5.16.2 represents approximately 2 months of development since Perl
+5.16.1 and contains approximately 740 lines of changes across 20 files
+from 9 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 5.16.2:
+
+Andy Dougherty, Craig A. Berry, Darin McBride, Dominic Hargreaves, Karen
+Etheridge, Karl Williamson, Peter Martini, Ricardo Signes, Tony Cook.
+
+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.
