perl5123delta1

Overview

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

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.
