Acknowledgements

       Perl 5.30.2 represents approximately 4 months of development since Perl 5.30.1 and
       contains approximately 2,100 lines of changes across 110 files from 15 authors.

       Excluding auto-generated files, documentation and release tools, there were approximately
       920 lines of changes to 30 .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 5.30.2:

       Chris 'BinGOs' Williams, Dan Book, David Mitchell, Hugo van der Sanden, Karen Etheridge,
       Karl Williamson, Matthew Horsfall, Nicolas R., Petr Písař, Renee Baecker, Sawyer X, Steve
       Hay, Tomasz Konojacki, Tony Cook, 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.

       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 AUTHORS
       file in the Perl source distribution.

Reporting Bugs

       If you find what you think is a bug, you might check the perl bug database at
       <https://rt.perl.org/>.  There may also be information at <http://www.perl.org/>, the Perl
       Home Page.

       If you believe you have an unreported bug, please open an issue at
       <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 "SECURITY VULNERABILITY CONTACT INFORMATION" in
       perlsec for details of how to report the issue.

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 "perlthanks" program:

           perlthanks

       This will send an email to the Perl 5 Porters list with your show of thanks.
