The following people are known to have contributed the improvements that  became\nPerl 5.24.2:\n\nAaron  Crane,  Abigail,  Aristotle  Pagaltzis,  Chris  'BinGOs'  Williams, Dan Collins, David\nMitchell, Eric Herman, Father Chrysostomos, James E Keenan, Karl Williamson, Lukas Mai, Renee\nBaecker, Ricardo Signes, Sawyer X, Stevan Little, Steve Hay, Tony Cook, Yves Orton.\n\nThe list above is almost certainly incomplete as it is automatically generated  from  version\ncontrol history.  In particular, it does not include the names of the (very much appreciated)\ncontributors who reported issues to the Perl bug tracker.\n\nMany  of  the  changes  included  in  this version originated in the CPAN modules included in\nPerl's core.  We're grateful to the entire CPAN community for helping Perl to flourish.\n\nFor a more complete list of all of Perl's historical contributors,  please  see  the  AUTHORS\nfile in the Perl source distribution.\n",

Be sure to trim your bug down to a tiny but sufficient test case.  Your bug report,\nalong with the output of \"perl -V\", will be sent off to perlbug@perl.org to  be  analysed  by\nthe Perl porting team.\n\nIf the bug you are reporting has security implications which make it inappropriate to send to\na  publicly  archived  mailing list, then see \"SECURITY VULNERABILITY CONTACT INFORMATION\" in\nperlsec for details of how to report the issue.\n",
