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.

Acknowledgements
       Perl 5.12.3 represents approximately four months of development since
       Perl 5.12.2 and contains approximately 2500 lines of changes across 54
       files from 16 authors.

       Perl continues to flourish into its third decade thanks to a vibrant
       community of users and developers.  The following people are known to
       have contributed the improvements that became Perl 5.12.3:

       Craig A. Berry, David Golden, David Leadbeater, Father Chrysostomos,
       Florian Ragwitz, Jesse Vincent, Karl Williamson, Nick Johnston, Nicolas
       Kaiser, Paul Green, Rafael Garcia-Suarez, Rainer Tammer, Ricardo
       Signes, Steffen Mueller, Zsban Ambrus, AEvar Arnfjoer` Bjarmason

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.
