perl5161delta - what is new for perl v5.16.1
This document describes differences between the 5.16.0 release and the 5.16.1 release.
If you are upgrading from an earlier release such as 5.14.0, first read perl5160delta, which describes differences between 5.14.0 and 5.16.0.
The bugfix was in Scalar-List-Util 1.23_04, and perl 5.16.1 includes Scalar-List-Util 1.25.
There are no changes intentionally incompatible with 5.16.0 If any exist, they are bugs, and we request that you submit a report. See "Reporting Bugs" below.

SEARCHLIST. Under some circumstances, the final instance was overriding all earlier ones. [perl #113584]
B::COP::stashlenhas been added. This provides access to an internal field added in perl 5.16 under threaded builds. It was broken at the last minute before 5.16 was released [perl #113034].

print &CORE::uc("a"), &CORE::uc("b")used to print "BB". The same thing would happen with an lvalue subroutine returning the return value of
uc. Now the value is copied in such cases [perl #113044].

Many of the changes included in this version originated in the CPAN modules included in Perl's core. We're grateful to the entire CPAN community for helping Perl to flourish.

will be sent off to email@example.com 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 firstname.lastname@example.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.
