[L] =back =head1 Obituary David H. Adler (DHA) passed away on November 16, 2021. In 1997, David co-founded NY.pm, the first Perl user group, and in 1998 co-founded Perl Mongers to help establish other user groups across the globe. He was a frequent attendee at Perl conferences in both North America and Europe and well known for his role in organizing I celebrations at those conferences. He also contributed to the work of the Perl Foundation, including administering the White Camel awards for community service. He will be sorely missed. =head1 Acknowledgements Perl 5.35.6 represents approximately 4 weeks of development since Perl 5.35.5 and contains approximately 16,000 lines of changes across 320 files from 10 authors. Excluding auto-generated files, documentation and release tools, there were approximately 13,000 lines of changes to 240 .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 5.35.6: Dagfinn Ilmari Mannsåker, H.Merijn Brand, James E Keenan, Leon Timmermans, Pete Houston, Ricardo Signes, Richard Leach, Robert Rothenberg, Sergey Poznyakoff, 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 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. There may also be information at L, the Perl Home Page. If you believe you have an unreported bug, please open an issue at L. 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 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 program: perlthanks This will send an email to the Perl 5 Porters list with your show of thanks. =head1 SEE ALSO The F file for an explanation of how to view exhaustive details on what changed.
