+=head1 Acknowledgements
+
+Perl 5.32.1 represents approximately 7 months of development since Perl 5.32.0
+and contains approximately 7,000 lines of changes across 80 files from 23
+authors.
+
+Excluding auto-generated files, documentation and release tools, there were
+approximately 1,300 lines of changes to 23 .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 5.32.1:
+
+Adam Hartley, Andy Dougherty, Dagfinn Ilmari Mannsåker, Dan Book, David
+Mitchell, Graham Knop, Graham Ollis, Hauke D, H.Merijn Brand, Hugo van der
+Sanden, John Lightsey, Karen Etheridge, Karl Williamson, Leon Timmermans, Max
+Maischein, Nicolas R., Ricardo Signes, Richard Leach, Sawyer X, Sevan Janiyan,
+Steve Hay, Tom Hukins, 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.
+
+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.

+
+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
