IInnccoommppaattiibbllee CChhaannggeess There are no changes intentionally incompatible with 5.24.3. If any exist, they are bugs, and we request that you submit a report. See “Reporting Bugs” below.

AAcckknnoowwlleeddggeemmeennttss Perl 5.24.4 represents approximately 7 months of development since Perl 5.24.3 and contains approximately 2,400 lines of changes across 49 files from 12 authors.

 Excluding auto-generated files, documentation and release tools, there
 were approximately 1,300 lines of changes to 12 .pm, .t, .c and .h files.

 Perl continues to flourish into its third decade thanks to a vibrant
 community of users and developers.  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 _A_U_T_H_O_R_S file in the Perl source distribution.

RReeppoorrttiinngg BBuuggss 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 https://rt.perl.org/ . There may also be information at http://www.perl.org/ , the Perl Home Page.

 If you believe you have an unreported bug, please run the 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 "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
 "SECURITY VULNERABILITY CONTACT INFORMATION" in perlsec for details of
 how to report the issue.
