The following people are known to have contributed +the improvements that became Perl 5.26.2: +.PP +Aaron Crane, Abigail, Chris 'BinGOs' Williams, H.Merijn Brand, James E Keenan, +Jarkko Hietaniemi, John SJ Anderson, Karen Etheridge, Karl Williamson, Lukas +Mai, Renee Baecker, Sawyer X, Steve Hay, Todd Rinaldo, Tony Cook, Yves Orton, +Zefram. +.PP +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. +.PP +Many of the changes included in this version originated in the CPAN modules +included in Perl's core.
