<p>perl5250delta - what is new for perl v5.25.0</p>

<h1 id="DESCRIPTION">DESCRIPTION</h1>

<p>This document describes differences between the 5.24.0 release and the 5.25.0 release.</p>

<h1 id="Known-Problems">Known Problems</h1>

<ul>

<li><p>Some modules have been broken by the <a href="#Internal-Changes">context stack rework</a>. These modules were relying on non-guaranteed implementation details in perl. Their maintainers have been informed, and should contact perl5-porters for advice if needed. Below is a subset of these modules:</p>

<dl>

<dt id="Algorithm::Permute"><a>Algorithm::Permute</a></dt>
<dd>

</dd>
<dt id="Coro"><a>Coro</a></dt>
<dd>

<p><a>Coro</a> and perl v5.22.0 were already incompatible due to a change in the perl, and the reworking on the perl context stack creates a further incompatibility. perl5-porters has <a href="http://www.nntp.perl.org/group/perl.perl5.porters/2016/05/msg236174.html">discussed the issue on the mailing list</a>.</p>

</dd>
<dt id="Data::Alias"><a>Data::Alias</a></dt>
<dd>

</dd>
<dt id="RPerl"><a>RPerl</a></dt>
<dd>

</dd>
<dt id="Scope::Upper"><a>Scope::Upper</a></dt>
<dd>

</dd>
<dt id="TryCatch"><a>TryCatch</a></dt>
<dd>

</dd>
</dl>

</li>
<li><p>The module <a>lexical::underscore</a> no longer works on perl v5.24.0, because perl no longer has a lexical <code>$_</code>!</p>

</li>
<li><p><code>mod_perl</code> has been patched for compatibility for v5.22.0 and later but no release has been made. The relevant patch (and other changes) can be found in their source code repository, <a href="https://github.com/apache/mod_perl/commit/82827132efd3c2e25cc413c85af61bb63375da6e">mirrored at GitHub</a>.</p>

<h1 id="Reporting-Bugs">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 <a href="https://rt.perl.org/">https://rt.perl.org/</a> . There may also be information at <a href="http://www.perl.org/">http://www.perl.org/</a> , the Perl Home Page.</p>

<p>If you believe you have an unreported bug, please run the <a>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 see <a href="/cperl/perlsec.html#SECURITY-VULNERABILITY-CONTACT-INFORMATION">&quot;SECURITY VULNERABILITY CONTACT INFORMATION&quot; in perlsec</a> for details of how to report the issue.</p>
