5 | perldelta - what is new for perl v5.12.3 | |
6 | ||
7 | =head1 DESCRIPTION | |
8 | ||
9 | This document describes differences between the 5.12.2 release and | |
10 | the 5.12.3 release. | |
11 | ||
12 | If you are upgrading from an earlier release such as 5.12.1, first read | |
13 | L<perl5122delta>, which describes differences between 5.12.1 and | |
14 | 5.12.2. 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 5.12.2. If any | |
19 | exist, they are bugs and reports are welcome. | |
20 | ||
21 | =head1 Core Enhancements | |
22 | ||
23 | =head2 C<keys>, C<values> work on arrays | |
24 | ||
25 | You can now use the C<keys>, C<values>, C<each> builtin functions on arrays | |
26 | (previously you could only use them on hashes). See L<perlfunc> for details. | |
27 | This is actually a change introduced in perl 5.12.0, but it was missed from | |
28 | that release's perldelta. | |
29 | ||
30 | =head1 Bug Fixes | |
31 | ||
32 | "no VERSION" will now correctly deparse with B::Deparse, as will certain | |
33 | constant expressions. | |
34 | ||
35 | Module::Build should be more reliably pass its tests under cygwin. | |
36 | ||
37 | lvalue sub return values are now COW. | |
38 | ||
39 | =head1 Platform Specific Notes | |
40 | ||
41 | =over 4 | |
42 | ||
43 | =item Solaris | |
44 | ||
45 | A separate DTrace is now build for miniperl, which means that perl can be | |
46 | compiled with -Dusedtrace on Solaris again. | |
47 | ||
48 | =item VMS | |
49 | ||
50 | A number of regressions on VMS have been fixed. In addition to minor cleanup | |
51 | of questionable expressions in F<vms.c>, file permissions should no longer be | |
52 | garbled by the PerlIO layer, and spurious record boundaries should no longer be | |
53 | introduced by the PerlIO layer during output. | |
54 | ||
55 | For more details and discussion on the latter, see: | |
56 | ||
57 | http://www.nntp.perl.org/group/perl.vmsperl/2010/11/msg15419.html | |
58 | ||
59 | =item VOS | |
60 | ||
61 | A few very small changes were made to the build process on VOS to better | |
62 | support the platform. Longer-than-32-character filenames are now supported on | |
63 | OpenVOS, and build properly without IPv6 support. | |

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