NAME
perl5123delta - what is new for perl v5.12.3
DESCRIPTION
This document describes differences between the 5.12.2 release and the
5.12.3 release.
If you are upgrading from an earlier release such as 5.12.1, first read
perl5122delta, which describes differences between 5.12.1 and 5.12.2.
The major changes made in 5.12.0 are described in perl5120delta.
Incompatible Changes
There are no changes intentionally incompatible with 5.12.2. If any
exist, they are bugs and reports are welcome.
Core Enhancements
"keys", "values" work on arrays
You can now use the "keys", "values", "each" builtin functions on
arrays (previously you could only use them on hashes). See perlfunc
for details. This is actually a change introduced in perl 5.12.0, but
it was missed from that release's perldelta.
Bug Fixes
"no VERSION" will now correctly deparse with B::Deparse, as will
certain constant expressions.
Module::Build should be more reliably pass its tests under cygwin.
Lvalue subroutines are again able to return copy-on-write scalars.
This had been broken since version 5.10.0.
Platform Specific Notes
Solaris
A separate DTrace is now build for miniperl, which means that perl
can be compiled with -Dusedtrace on Solaris again.
VMS A number of regressions on VMS have been fixed. In addition to
minor cleanup of questionable expressions in vms.c, file
permissions should no longer be garbled by the PerlIO layer, and
spurious record boundaries should no longer be introduced by the
PerlIO layer during output.
For more details and discussion on the latter, see:
http://www.nntp.perl.org/group/perl.vmsperl/2010/11/msg15419.html
VOS A few very small changes were made to the build process on VOS to
better support the platform. Longer-than-32-character filenames
are now supported on OpenVOS, and build properly without IPv6
support.

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