Source   Latest Release: perl-5.14.4

NAME ^

perl5115delta - what is new for perl v5.11.5

DESCRIPTION ^

This document describes differences between the 5.11.4 release and the 5.11.5 release.

If you are upgrading from an earlier release such as 5.11.3, first read perl5114delta, which describes differences between 5.11.3 and 5.11.4.

Core Enhancements ^

32-bit limit on substr arguments removed

The 32-bit limit on substr arguments has now been removed. The full range of the system's signed and unsigned integers is now available for the pos and len arguments.

Modules and Pragmata ^

Pragmata Changes

version

Upgraded from version 0.81 to 0.82.

The is_lax and is_strict functions can now be optionally exported to the caller's namespace and are also now documented.

Undefined version objects are now uninitialized with zero rather than undef.

Updated Modules

B::Debug

Upgraded from version 1.11 to 1.12.

CPAN

Upgraded from version 1.94_53 to 1.94_56.

This resolves RT #72362, in which CPAN was ignoring configure_requires, and RT #72348, in which the command o conf init in the CPAN shell could cause an exception to be thrown.

This module is also now built in a less specialized way, which resolves a problem that caused make after make clean to fail, fixing RT #72218.

CPANPLUS::Dist::Build

Upgraded from version 0.44 to 0.46.

This makes the prereq resolving fall back to _build/ querying if the prereq_data action fails.

Pod::Perldoc

Upgraded from version 3.15_01 to 3.15_02.

Pod::Plainer

Upgraded from version 1.01 to 1.02.

Safe

Upgraded from version 2.21 to 2.22.

This resolves RT #72700, in which an exception thrown from a closure was getting lost.

Socket

Upgraded from version 1.85 to 1.86.

This makes the new Socket implementation of inet_pton consistent with the existing Socket6 implementation of inet_pton, fixing RT #72884.

podlators

Upgraded from version 2.2.2 to 2.3.1.

Changes to Existing Documentation ^

The syntax unless (EXPR) BLOCK else BLOCK is now documented as valid, as is the syntax unless (EXPR) BLOCK elsif (EXPR) BLOCK ... else BLOCK, although actually using the latter may not be the best idea for the readability of your source code.

Installation and Configuration Improvements ^

Configuration improvements

Support for SystemTap's dtrace compatibility layer has been added and an issue with linking miniperl has been fixed in the process.

less -R is now used instead of less for groff's new usage of ANSI escape codes by setting $Config{less} (and thereby $Config{pager}, which fixes RT #72156.

USE_PERL_ATOF is now reported in the compile-time options listed by the -V switch.

Selected Bug Fixes ^

New or Changed Diagnostics ^

New Tests ^

t/op/filehandle.t

Tests some suitably portable filetest operators to check that they work as expected, particularly in the light of some internal changes made in how filehandles are blessed.

t/op/time_loop.t

Tests that times greater than 2**63, which can now be handed to gmtime and localtime, do not cause an internal overflow or an excessively long loop.

Known Problems ^

Perl 5.11.5 is a development release leading up to Perl 5.12.0. Some notable known problems found in 5.11.5 are listed as dependencies of RT #69710, the Perl 5 version 12 meta-ticket.

Acknowledgements ^

Perl 5.11.5 represents approximately one month of development since Perl 5.11.4 and contains 9618 lines of changes across 151 files from 33 authors and committers:

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.

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 analyzed 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.
