The following people are known to have contributed the improvements that became Perl 5.14.4:</p> <p>Andy Dougherty, Chris 'BinGOs' Williams, Christian Hansen, Craig A. Berry, Dave Rolsky, David Mitchell, Dominic Hargreaves, Father Chrysostomos, Florian Ragwitz, Reini Urban, Ricardo Signes, Yves Orton.</p> <p>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.</p> <p>For a more complete list of all of Perl's historical contributors, please see the <i>AUTHORS</i> file in the Perl source distribution.</p> <h1 id="Reporting-Bugs"><a class="permalink" href="#Reporting-Bugs">#</a><a id="Reporting"></a>Reporting Bugs</h1> <p>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 http://rt.perl.org/perlbug/ . There may also be information at http://www.perl.org/ , the Perl Home Page.</p> <p>If you believe you have an unreported bug, please run the <a href="/5.14.4/perlbug">perlbug</a> 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 <code>perl -V</code>, will be sent off to perlbug@perl.org to be analysed by the Perl porting team.</p> <p>If the bug you are reporting has security implications, which make it inappropriate to send to a publicly archived mailing list, then please send it to perl5-security-report@perl.org. This points to a closed subscription unarchived mailing list, which includes all the core committers, who be able to help assess the impact of issues, figure out a resolution, and help co-ordinate the release of patches to mitigate or fix the problem across all platforms on which Perl is supported. Please only use this address for security issues in the Perl core, not for modules independently distributed on CPAN.</p> <h1 id="SEE-ALSO"><a class="permalink" href="#SEE-ALSO">#</a><a id="SEE"></a>SEE ALSO</h1> <p>The <i>Changes</i> file for an explanation of how to view exhaustive details on what changed.</p> <p>The <i>INSTALL</i> file for how to build Perl.</p> <p>The <i>README</i> file for general stuff.</p> <p>The <i>Artistic</i> and <i>Copying</i> files for copyright information.</p> </div> <div id="footer"> <p>Perldoc Browser is maintained by Dan Book (<a href="https://metacpan.org/author/DBOOK">DBOOK</a>).
