+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 *
+
+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 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.
