DDEESSCCRRIIPPTTIIOONN #

 This document describes differences between the 5.18.1 release and the
 5.18.2 release.

 If you are upgrading from an earlier release such as 5.18.0, first read
 perl5181delta, which describes differences between 5.18.0 and 5.18.1.

MMoodduulleess aanndd PPrraaggmmaattaa UUppddaatteedd MMoodduulleess aanndd PPrraaggmmaattaa • 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 "B::CV::GV", changing the return value from a "B::SPECIAL" object
     on a "NULL" "CvGV" to "undef".  "B::CV::GV" again returns a
     "B::SPECIAL" object in this case.  [perl #119413]

 •   B::Concise has been upgraded from version 0.95 to 0.95_01.

     This fixes a bug in dumping unexpected SPECIALs.

 •   English has been upgraded from version 1.06 to 1.06_01.  This fixes
     an error about the performance of "$`", $&, and "$'".

 •   File::Glob has been upgraded from version 1.20 to 1.20_01.

DDooccuummeennttaattiioonn CChhaannggeess ttoo EExxiissttiinngg DDooccuummeennttaattiioonn • perlrepository has been restored with a pointer to more useful pages.

 •   perlhack has been updated with the latest changes from blead.

SSeelleecctteedd BBuugg FFiixxeess • 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]

 •   Perl 5.18.0 introduced a regression whereby "[:^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]

 •   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]

 •   Perl 5.18.0 introduced a regression whereby "-bareword" was no longer
     permitted under the "strict" and "integer" pragmata when used
     together.  This has been fixed.  [perl #120288]

 •   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.

 •   A buffer overflow with very long identifiers has been fixed.

 •   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.

 •   The construct "$r=qr/.../; /$r/p" is now handled properly, an issue
     which had been worsened by changes 5.18.0. [perl #118213]

AAcckknnoowwlleeddggeemmeennttss 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 _A_U_T_H_O_R_S file in the Perl source distribution.

RReeppoorrttiinngg BBuuggss 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 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 "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.
