The following people are known to have contributed +the improvements that became Perl 5.24.4: + +Abigail, Chris 'BinGOs' Williams, John SJ Anderson, Karen Etheridge, Karl +Williamson, Renee Baecker, Sawyer X, Steve Hay, Todd Rinaldo, 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 articles recently +posted to the comp.lang.perl.misc newsgroup and the perl bug database at +L<https://rt.perl.org/> . There may also be information at +L<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 see +L<perlsec/SECURITY VULNERABILITY CONTACT INFORMATION> +for details of how to report the issue. + +=head1 SEE ALSO + +The F<Changes> file for an explanation of how to view exhaustive details on +what changed. + +The F<INSTALL> file for how to build Perl. + +The F<README> file for general stuff. + +The F<Artistic> and F<Copying> files for copyright information. + +=cut |
