+perl5184delta - what is new for perl v5.18.4
+
+=head1 DESCRIPTION
+
+This document describes differences between the 5.18.4 release and the 5.18.2
+release.  B<Please note:>  This document ignores perl 5.18.3, a broken release
+which existed for a few hours only.
+
+If you are upgrading from an earlier release such as 5.18.1, first read
+L<perl5182delta>, which describes differences between 5.18.1 and 5.18.2.

+Introduced by
+L<perl #113536|https://rt.perl.org/Public/Bug/Display.html?id=113536>, a memory
+leak on every call to C<system> and backticks (C< `` >), on most Win32 Perls
+starting from 5.18.0 has been fixed.  The memory leak only occurred if you
+enabled psuedo-fork in your build of Win32 Perl, and were running that build on
+Server 2003 R2 or newer OS.  The leak does not appear on WinXP SP3.

+In Perl v5.18 C<undef *_; goto &sub> and C<local *_; goto &sub> started

+=head1 Acknowledgements
+
+Perl 5.18.4 represents approximately 9 months of development since Perl 5.18.2
+and contains approximately 2,000 lines of changes across 53 files from 13
+authors.
+
+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 5.18.4:
+
+Daniel Dragan, David Mitchell, Doug Bell, Father Chrysostomos, Hiroo Hayashi,
+James E Keenan, Karl Williamson, Mark Shelor, Ricardo Signes, Shlomi Fish,
+Smylers, Steve Hay, Tony Cook.
+
+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 F<AUTHORS> file in the Perl source distribution.
+
+=head1 Reporting Bugs
+
+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.
+
+If you believe you have an unreported bug, please run the L<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 C<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 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 will 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.
