+=head1 Acknowledgements
+
+Perl 5.37.11 represents approximately 4 weeks of development since Perl 5.37.10
+and contains approximately 5,500 lines of changes across 180 files from 16
+authors.
+
+Excluding auto-generated files, documentation and release tools, there were
+approximately 3,000 lines of changes to 110 .pm, .t, .c and .h files.
+
+Perl continues to flourish into its fourth decade thanks to a vibrant community
+of users and developers.  The following people are known to have contributed
+the improvements that became Perl 5.37.11:
+
+Craig A. Berry, Dan Book, David Cantrell, Karl Williamson, Leon Timmermans,
+Lukas Mai, Nicolas R, Paul Evans, Philippe Bruhat (BooK), Scott Baker, Sevan
+Janiyan, Steve Hay, Tomasz Konojacki, Tony Cook, Yves Orton, Zefram.
+
+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.
+
+Many of the changes included in this version originated in the CPAN modules
+included in Perl's core.  We're grateful to the entire CPAN community for
+helping Perl to flourish.
+
+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 perl bug database at
+L<https://github.com/Perl/perl5/issues>.  There may also be information at
+L<http://www.perl.org/>, the Perl Home Page.
+
+If you believe you have an unreported bug, please open an issue at
+L<https://github.com/Perl/perl5/issues>.  Be sure to trim your bug down to a
+tiny but sufficient test case.
+
+If the bug you are reporting has security implications which make it
+inappropriate to send to a public issue tracker, then see
+L<perlsec/SECURITY VULNERABILITY CONTACT INFORMATION> for details of how to
+report the issue.
+
+=head1 Give Thanks
+
+If you wish to thank the Perl 5 Porters for the work we had done in Perl 5, you
+can do so by running the C<perlthanks> program:
+
+    perlthanks
+
+This will send an email to the Perl 5 Porters list with your show of thanks.

+=head1 Deprecations
+
+XXX Any deprecated features, syntax, modules etc. should be listed here.

+=head2 Module removals
+
+XXX Remove this section if not applicable.
+
+The following modules will be removed from the core distribution in a
+future release, and will at that time need to be installed from CPAN.
+Distributions on CPAN which require these modules will need to list them as
+prerequisites.
+
+The core versions of these modules will now issue C<"deprecated">-category
+warnings to alert you to this fact.  To silence these deprecation warnings,
+install the modules in question from CPAN.
+
+Note that these are (with rare exceptions) fine modules that you are encouraged
+to continue to use.  Their disinclusion from core primarily hinges on their
+necessity to bootstrapping a fully functional, CPAN-capable Perl installation,
+not usually on concerns over their design.
