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. + +=back + +=head1 Documentation + +=head2 Changes to Existing Documentation + +=over 4 + +=item * + +L<perlrepository> has been restored with a pointer to more useful pages. + +=item * + +L<perlhack> has been updated with the latest changes from blead. + +=back + +=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] + +=back + +=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 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. + +=head1 SEE ALSO + +The F<Changes> file for an explanation of how to view exhaustive details on +what changed. + +The F<INSTALL> file for how to build Perl. + +The F<README> file for general stuff. + +The F<Artistic> and F<Copying> files for copyright information. + +=cut |
