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.
