perl5123delta - what is new for perl v5.12.3


   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

       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:


   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


   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

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 .  There may also be
   information at , 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 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 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.
