DESCRIPTION

9       This document describes differences between the 5.18.1 release and the
10       5.18.2 release.
11
12       If you are upgrading from an earlier release such as 5.18.0, first read
13       perl5181delta, which describes differences between 5.18.0 and 5.18.1.
14

Modules and Pragmata

16   Updated Modules and Pragmata
17       •   B has been upgraded from version 1.42_01 to 1.42_02.
18
19           The fix for [perl #118525] introduced a regression in the behaviour
20           of "B::CV::GV", changing the return value from a "B::SPECIAL"
21           object on a "NULL" "CvGV" to "undef".  "B::CV::GV" again returns a
22           "B::SPECIAL" object in this case.  [perl #119413]
23
24       •   B::Concise has been upgraded from version 0.95 to 0.95_01.
25
26           This fixes a bug in dumping unexpected SPECIALs.
27
28       •   English has been upgraded from version 1.06 to 1.06_01.  This fixes
29           an error about the performance of "$`", $&, and "$'".
30
31       •   File::Glob has been upgraded from version 1.20 to 1.20_01.
32

Documentation

34   Changes to Existing Documentation
35       •   perlrepository has been restored with a pointer to more useful
36           pages.
37
38       •   perlhack has been updated with the latest changes from blead.
39

Selected Bug Fixes

41       •   Perl 5.18.1 introduced a regression along with a bugfix for lexical
42           subs.  Some B::SPECIAL results from B::CV::GV became undefs
43           instead.  This broke Devel::Cover among other libraries.  This has
44           been fixed.  [perl #119351]
45
46       •   Perl 5.18.0 introduced a regression whereby "[:^ascii:]", if used
47           in the same character class as other qualifiers, would fail to
48           match characters in the Latin-1 block.  This has been fixed.  [perl
49           #120799]
50
51       •   Perl 5.18.0 introduced a regression when using ->SUPER::method with
52           AUTOLOAD by looking up AUTOLOAD from the current package, rather
53           than the current package’s superclass.  This has been fixed. [perl
54           #120694]
55
56       •   Perl 5.18.0 introduced a regression whereby "-bareword" was no
57           longer permitted under the "strict" and "integer" pragmata when
58           used together.  This has been fixed.  [perl #120288]
59
60       •   Previously PerlIOBase_dup didn't check if pushing the new layer
61           succeeded before (optionally) setting the utf8 flag. This could
62           cause segfaults-by-nullpointer.  This has been fixed.
63
64       •   A buffer overflow with very long identifiers has been fixed.
65
66       •   A regression from 5.16 in the handling of padranges led to
67           assertion failures if a keyword plugin declined to handle the
68           second ‘my’, but only after creating a padop.
69
70           This affected, at least, Devel::CallParser under threaded builds.
71
72           This has been fixed.
73
74       •   The construct "$r=qr/.../; /$r/p" is now handled properly, an issue
75           which had been worsened by changes 5.18.0. [perl #118213]

88       The list above is almost certainly incomplete as it is automatically
89       generated from version control history. In particular, it does not
90       include the names of the (very much appreciated) contributors who
91       reported issues to the Perl bug tracker.
92
93       Many of the changes included in this version originated in the CPAN
94       modules included in Perl's core. We're grateful to the entire CPAN
95       community for helping Perl to flourish.

Reporting Bugs

101       If you find what you think is a bug, you might check the articles
102       recently posted to the comp.lang.perl.misc newsgroup and the perl bug
103       database at http://rt.perl.org/perlbug/ .  There may also be
104       information at http://www.perl.org/ , the Perl Home Page.
105
106       If you believe you have an unreported bug, please run the perlbug
107       program included with your release.  Be sure to trim your bug down to a
108       tiny but sufficient test case.  Your bug report, along with the output
109       of "perl -V", will be sent off to perlbug@perl.org to be analysed by
110       the Perl porting team.
111
112       If the bug you are reporting has security implications, which make it
113       inappropriate to send to a publicly archived mailing list, then please
114       send it to perl5-security-report@perl.org.  This points to a closed
115       subscription unarchived mailing list, which includes all the core
116       committers, who will be able to help assess the impact of issues,
117       figure out a resolution, and help co-ordinate the release of patches to
118       mitigate or fix the problem across all platforms on which Perl is
119       supported.  Please only use this address for security issues in the
120       Perl core, not for modules independently distributed on CPAN.
