6 perldelta - what is new for perl v5.12.3
7
9 This document describes differences between the 5.12.2 release and the
10 5.12.3 release.
11 If you are upgrading from an earlier release such as 5.12.1, first read
13 perl5122delta, which describes differences between 5.12.1 and 5.12.2.
14 The major changes made in 5.12.0 are described in perl5120delta.
15
17 There are no changes intentionally incompatible with 5.12.2. If any
18 exist, they are bugs and reports are welcome.
19
21 "keys", "values" work on arrays
22 You can now use the "keys", "values", "each" builtin functions on
23 arrays (previously you could only use them on hashes). See perlfunc
24 for details. This is actually a change introduced in perl 5.12.0, but
25 it was missed from that release's perldelta.
26
28 "no VERSION" will now correctly deparse with B::Deparse, as will
29 certain constant expressions.
30 Module::Build should be more reliably pass its tests under cygwin.
32 lvalue sub return values are now COW.
34
36 Solaris
37 A separate DTrace is now build for miniperl, which means that perl
38 can be compiled with -Dusedtrace on Solaris again.
39 VMS A number of regressions on VMS have been fixed. In addition to
41 minor cleanup of questionable expressions in vms.c, file
42 permissions should no longer be garbled by the PerlIO layer, and
43 spurious record boundaries should no longer be introduced by the
44 PerlIO layer during output.
45 For more details and discussion on the latter, see:
47 http://www.nntp.perl.org/group/perl.vmsperl/2010/11/msg15419.html
49 VOS A few very small changes were made to the build process on VOS to
51 better support the platform. Longer-than-32-character filenames
52 are now supported on OpenVOS, and build properly without IPv6
53 support.
54
56 Perl 5.12.3 represents approximately four months of development since
57 Perl 5.12.2 and contains approximately 2500 lines of changes across 54
58 files from 16 authors.
59 Perl continues to flourish into its third decade thanks to a vibrant
61 community of users and developers. The following people are known to
62 have contributed the improvements that became Perl 5.12.3:
63 Craig A. Berry, David Golden, David Leadbeater, Father Chrysostomos,
65 Florian Ragwitz, Jesse Vincent, Karl Williamson, Nick Johnston, Nicolas
66 Kaiser, Paul Green, Rafael Garcia-Suarez, Rainer Tammer, Ricardo
67 Signes, Steffen Mueller, Zsban Ambrus, var Arnfjoerd` Bjarmason

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