5perldelta - what is new for perl v5.12.3
6
7=head1 DESCRIPTION
8
9This document describes differences between the 5.12.2 release and
10the 5.12.3 release.
11
12If you are upgrading from an earlier release such as 5.12.1, first read
13L<perl5122delta>, which describes differences between 5.12.1 and
145.12.2. 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
25You 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.
27This is actually a change introduced in perl 5.12.0, but it was missed from
28that release's perldelta.
29
30=head1 Bug Fixes
31
32"no VERSION" will now correctly deparse with B::Deparse, as will certain
33constant expressions.
34
35Module::Build should be more reliably pass its tests under cygwin.
36

FC
37Lvalue subroutines are again able to return copy-on-write scalars. This
38had been broken since version 5.10.0.

40=head1 Platform Specific Notes
41
42=over 4
43
44=item Solaris
45
46A separate DTrace is now build for miniperl, which means that perl can be
47compiled with -Dusedtrace on Solaris again.
48
49=item VMS
50
51A number of regressions on VMS have been fixed. In addition to minor cleanup
52of questionable expressions in F<vms.c>, file permissions should no longer be
53garbled by the PerlIO layer, and spurious record boundaries should no longer be
54introduced by the PerlIO layer during output.
55
56For more details and discussion on the latter, see:

58 http://www.nntp.perl.org/group/perl.vmsperl/2010/11/msg15419.html
59
60=item VOS
61
62A few very small changes were made to the build process on VOS to better
63support the platform. Longer-than-32-character filenames are now supported on
64OpenVOS, and build properly without IPv6 support.

83=head1 Reporting Bugs
84
85If you find what you think is a bug, you might check the articles
86recently posted to the comp.lang.perl.misc newsgroup and the perl
87bug database at http://rt.perl.org/perlbug/ . There may also be
88information at http://www.perl.org/ , the Perl Home Page.
89
90If you believe you have an unreported bug, please run the B<perlbug>
91program included with your release. Be sure to trim your bug down
92to a tiny but sufficient test case. Your bug report, along with the
93output of C<perl -V>, will be sent off to perlbug@perl.org to be
94analysed by the Perl porting team.
95
96If the bug you are reporting has security implications, which make it
97inappropriate to send to a publicly archived mailing list, then please send
98it to perl5-security-report@perl.org. This points to a closed subscription
99unarchived mailing list, which includes all the core committers, who be able
100to help assess the impact of issues, figure out a resolution, and help
101co-ordinate the release of patches to mitigate or fix the problem across all
102platforms on which Perl is supported. Please only use this address for
103security issues in the Perl core, not for modules independently
104distributed on CPAN.
