The following people are known to have contributed 122the improvements that became Perl 5.30.2: 123 124Chris 'BinGOs' Williams, Dan Book, David Mitchell, Hugo van der Sanden, Karen 125Etheridge, Karl Williamson, Matthew Horsfall, Nicolas R., Petr Písař, Renee 126Baecker, Sawyer X, Steve Hay, Tomasz Konojacki, Tony Cook, Yves Orton. 127 128The list above is almost certainly incomplete as it is automatically generated 129from version control history. In particular, it does not include the names of 130the (very much appreciated) contributors who reported issues to the Perl bug 131tracker. 132 133Many of the changes included in this version originated in the CPAN modules 134included in Perl's core. We're grateful to the entire CPAN community for 135helping Perl to flourish. 136 137For a more complete list of all of Perl's historical contributors, please see 138the F<AUTHORS> file in the Perl source distribution. 139 140=head1 Reporting Bugs 141 142If you find what you think is a bug, you might check the perl bug database at 143L<https://rt.perl.org/>.
