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.
- 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 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.
