7 | =head1 DESCRIPTION | |
8 | ||
9 | This document describes differences between the 5.18.4 release and the 5.18.2 | |
10 | release. B<Please note:> This document ignores perl 5.18.3, a broken release | |
11 | which existed for a few hours only. | |
12 | ||
13 | If you are upgrading from an earlier release such as 5.18.1, first read | |
14 | L<perl5182delta>, which describes differences between 5.18.1 and 5.18.2. | |

28 | L<perl5db.pl> has been upgraded from version 1.39_10 to 1.39_11. | |

31 | filehandle information is properly reset after a pager is run. [perl #121456] | |

29c6c804 | 48 | L<[GH #12161]|https://github.com/Perl/perl5/issues/12161>, a memory |
e990b849 FC |
49 | leak on every call to C<system> and backticks (C< `` >), on most Win32 Perls |
50 | starting from 5.18.0 has been fixed. The memory leak only occurred if you | |
33f0d962 | 51 | enabled pseudo-fork in your build of Win32 Perl, and were running that build on |
e990b849 | 52 | Server 2003 R2 or newer OS. The leak does not appear on WinXP SP3. |

69 | A segfault in Digest::SHA has been addressed. [perl #121421] | |

73 | perl can again be built with USE_64_BIT_INT, with Visual C 2003, 32 bit. | |

82 | Copy the values used to perturb hash iteration when cloning an | |

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

95 | Perl 5.18.4 represents approximately 9 months of development since Perl 5.18.2 | |
96 | and contains approximately 2,000 lines of changes across 53 files from 13 | |
97 | authors. | |
98 | ||
99 | Perl continues to flourish into its third decade thanks to a vibrant community | |
100 | of users and developers. The following people are known to have contributed the | |
101 | improvements that became Perl 5.18.4: | |
102 | ||
103 | Daniel Dragan, David Mitchell, Doug Bell, Father Chrysostomos, Hiroo Hayashi, | |
104 | James E Keenan, Karl Williamson, Mark Shelor, Ricardo Signes, Shlomi Fish, | |
105 | Smylers, Steve Hay, Tony Cook. | |
106 | ||
107 | The list above is almost certainly incomplete as it is automatically generated | |
108 | from version control history. In particular, it does not include the names of | |
109 | the (very much appreciated) contributors who reported issues to the Perl bug | |
110 | tracker. | |
111 | ||
112 | Many of the changes included in this version originated in the CPAN modules | |
113 | included in Perl's core. We're grateful to the entire CPAN community for | |
114 | helping Perl to flourish. | |
115 | ||
116 | For a more complete list of all of Perl's historical contributors, please see | |
117 | the F<AUTHORS> file in the Perl source distribution. | |

119 | =head1 Reporting Bugs | |
120 | ||
121 | If you find what you think is a bug, you might check the articles recently | |
122 | posted to the comp.lang.perl.misc newsgroup and the perl bug database at | |
123 | http://rt.perl.org/perlbug/ . There may also be information at | |
124 | http://www.perl.org/ , the Perl Home Page. | |
125 | ||
126 | If you believe you have an unreported bug, please run the L<perlbug> program | |
127 | included with your release. Be sure to trim your bug down to a tiny but | |
128 | sufficient test case. Your bug report, along with the output of C<perl -V>, | |
129 | will be sent off to perlbug@perl.org to be analysed by the Perl porting team. | |
130 | ||
131 | If the bug you are reporting has security implications, which make it | |
132 | inappropriate to send to a publicly archived mailing list, then please send it | |
133 | to perl5-security-report@perl.org. This points to a closed subscription | |
134 | unarchived mailing list, which includes all the core committers, who will be | |
135 | able to help assess the impact of issues, figure out a resolution, and help | |
136 | co-ordinate the release of patches to mitigate or fix the problem across all | |
137 | platforms on which Perl is supported. Please only use this address for | |
138 | security issues in the Perl core, not for modules independently distributed on | |
139 | CPAN. | |
