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.

=head1 Reporting Bugs
|
|
|
|
If you find what you think is a bug, you might check 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 open an issue at
|
|
L<https://github.com/Perl/perl5/issues>. 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<perlsec/SECURITY
|
|
VULNERABILITY CONTACT INFORMATION> for details of how to report the issue.
