5 | perl5124delta - what is new for perl v5.12.4 | |
6 | ||
7 | =head1 DESCRIPTION | |
8 | ||
9 | This document describes differences between the 5.12.3 release and | |
10 | the 5.12.4 release. | |
11 | ||
12 | If you are upgrading from an earlier release such as 5.12.2, first read | |
13 | L<perl5123delta>, which describes differences between 5.12.2 | |
14 | and 5.12.3. The major changes made in 5.12.0 are described in L<perl5120delta>. | |
15 | ||
16 | =head1 Incompatible Changes | |
17 | ||
18 | There are no changes intentionally incompatible with 5.12.3. If any | |
19 | exist, they are bugs and reports are welcome. | |
20 | ||
21 | =head1 Selected Bug Fixes | |
22 | ||
23 | When strict "refs" mode is off, C<%{...}> in rvalue context returns | |
24 | C<undef> if its argument is undefined. An optimisation introduced in Perl | |
25 | 5.12.0 to make C<keys %{...}> faster when used as a boolean did not take | |
26 | this into account, causing C<keys %{+undef}> (and C<keys %$foo> when | |
27 | C<$foo> is undefined) to be an error, which it should be so in strict | |
28 | mode only [perl #81750]. | |
29 | ||
30 | C<lc>, C<uc>, C<lcfirst>, and C<ucfirst> no longer return untainted strings | |
31 | when the argument is tainted. This has been broken since perl 5.8.9 | |
32 | [perl #87336]. | |
33 | ||
34 | Fixed a case where it was possible that a freed buffer may have been read | |
35 | from when parsing a here document. | |
36 | ||
37 | =head1 Modules and Pragmata | |
38 | ||
39 | L<Module::CoreList> has been upgraded from version 2.43 to 2.50. | |
40 | ||
41 | =head1 Testing | |
42 | ||
43 | The F<cpan/CGI/t/http.t> test script has been fixed to work when the | |
44 | environment has HTTPS_* environment variables, such as HTTPS_PROXY. | |
45 | ||
46 | =head1 Documentation | |
47 | ||
48 | Updated the documentation for rand() in L<perlfunc> to note that it is not | |
49 | cryptographically secure. | |

63 | Perl 5.12.4 represents approximately 5 months of development since | |
64 | Perl 5.12.3 and contains approximately 200 lines of changes across | |
65 | 11 files from 8 authors. | |
66 | ||
67 | Perl continues to flourish into its third decade thanks to a vibrant | |
68 | community of users and developers. The following people are known to | |
69 | have contributed the improvements that became Perl 5.12.4: | |
70 | ||
71 | Andy Dougherty, David Golden, David Leadbeater, Father Chrysostomos, | |
72 | Florian Ragwitz, Jesse Vincent, Leon Brocard, Zsbán Ambrus. | |

74 | =head1 Reporting Bugs | |
75 | ||
76 | If you find what you think is a bug, you might check the articles | |
77 | recently posted to the comp.lang.perl.misc newsgroup and the perl | |
78 | bug database at http://rt.perl.org/perlbug/ . There may also be | |
79 | information at http://www.perl.org/ , the Perl Home Page. | |
80 | ||
81 | If you believe you have an unreported bug, please run the B<perlbug> | |
82 | program included with your release. Be sure to trim your bug down | |
83 | to a tiny but sufficient test case. Your bug report, along with the | |
84 | output of C<perl -V>, will be sent off to perlbug@perl.org to be | |
85 | analysed by the Perl porting team. | |
86 | ||
87 | If the bug you are reporting has security implications, which make it | |
88 | inappropriate to send to a publicly archived mailing list, then please send | |
89 | it to perl5-security-report@perl.org. This points to a closed subscription | |
90 | unarchived mailing list, which includes all the core committers, who be able | |
91 | to help assess the impact of issues, figure out a resolution, and help | |
92 | co-ordinate the release of patches to mitigate or fix the problem across all | |
93 | platforms on which Perl is supported. Please only use this address for | |
94 | security issues in the Perl core, not for modules independently | |
95 | distributed on CPAN. | |
