| =head1 DESCRIPTION | |
| This document describes differences between the 5.18.1 release and the 5.18.2 | |
| release. | |

| L<B> has been upgraded from version 1.42_01 to 1.42_02. | |
| The fix for [perl #118525] introduced a regression in the behaviour of | |
| C<B::CV::GV>, changing the return value from a C<B::SPECIAL> object on | |
| a C<NULL> C<CvGV> to C<undef>. C<B::CV::GV> again returns a | |
| C<B::SPECIAL> object in this case. [perl #119413] | |
| =item * | |
| L<B::Concise> has been upgraded from version 0.95 to 0.95_01. | |
| This fixes a bug in dumping unexpected SPECIALs. | |
| =item * | |
| L<English> has been upgraded from version 1.06 to 1.06_01. This fixes an | |
| error about the performance of C<$`>, C<$&>, and C<$'>. | |
| =item * | |
| L<File::Glob> has been upgraded from version 1.20 to 1.20_01. | |

| =head1 Selected Bug Fixes | |
| =over 4 | |
| =item * | |
| Perl 5.18.1 introduced a regression along with a bugfix for lexical subs. | |
| Some B::SPECIAL results from B::CV::GV became undefs instead. This broke | |
| Devel::Cover among other libraries. This has been fixed. [perl #119351] | |
| =item * | |
| Perl 5.18.0 introduced a regression whereby C<[:^ascii:]>, if used in the same | |
| character class as other qualifiers, would fail to match characters in the | |
| Latin-1 block. This has been fixed. [perl #120799] | |
| =item * | |
| Perl 5.18.0 introduced a regression when using ->SUPER::method with AUTOLOAD | |
| by looking up AUTOLOAD from the current package, rather than the current | |
| package’s superclass. This has been fixed. [perl #120694] | |
| =item * | |
| Perl 5.18.0 introduced a regression whereby C<-bareword> was no longer | |
| permitted under the C<strict> and C<integer> pragmata when used together. This | |
| has been fixed. [perl #120288] | |
| =item * | |
| Previously PerlIOBase_dup didn't check if pushing the new layer succeeded | |
| before (optionally) setting the utf8 flag. This could cause | |
| segfaults-by-nullpointer. This has been fixed. | |
| =item * | |
| A buffer overflow with very long identifiers has been fixed. | |
| =item * | |
| A regression from 5.16 in the handling of padranges led to assertion failures | |
| if a keyword plugin declined to handle the second ‘my’, but only after creating | |
| a padop. | |
| This affected, at least, Devel::CallParser under threaded builds. | |
| This has been fixed. | |
| =item * | |
| The construct C<< $r=qr/.../; /$r/p >> is now handled properly, an issue which | |
| had been worsened by changes 5.18.0. [perl #118213] | |

| =head1 Acknowledgements | |
| Perl 5.18.2 represents approximately 3 months of development since Perl | |
| 5.18.1 and contains approximately 980 lines of changes across 39 files from 4 | |
| 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 5.18.2: | |
| Craig A. Berry, David Mitchell, Ricardo Signes, 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 [email protected] 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 [email protected]. 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. | |
