NAME

perl5411delta - what is new for perl v5.41.1

DESCRIPTION

This document describes differences between the 5.41.0 release and the 5.41.1 release.

If you are upgrading from an earlier release such as 5.40.0, first read perl5410delta, which describes differences between 5.40.0 and 5.41.0.

Core Enhancements

More CORE:: subs

chdir has been added as a subroutine to the CORE:: namespace.

Previously, code like &CORE::chdir($dir) or my $ref = \&CORE::chdir; $ref->($dir) would throw an error saying &CORE::chdir cannot be called directly. These cases are now fully supported.

Performance Enhancements

  • Various optimizations related to handling of CONSTs.

  • Perl_leave_adjust_stacks: additional efficiency for mortal copies.

Modules and Pragmata

Updated Modules and Pragmata

  • builtin has been upgraded from version 0.014 to 0.015.

    Documented when each builtin function was first available and stabilized.

  • Data::Dumper has been upgraded from version 2.189 to 2.190.

  • ExtUtils::ParseXS has been upgraded from version 3.51 to 3.52.

Documentation

Changes to Existing Documentation

We have attempted to update the documentation to reflect the changes listed in this document. If you find any we have missed, open an issue at https://github.com/Perl/perl5/issues.

Additionally, the following selected changes have been made:

perlapi

  • Combined the documentation for several groups of related functions into single entries.

perlfunc

  • Clarified the description of ref and reftype in relation to built-in types and class names.

  • Clarified that perl sort is stable (and has been since v5.8.0).

perlguts

  • Added some description of "real" AVs compared to "fake" AVs.

Testing

Tests were added and changed to reflect the other additions and changes in this release. Furthermore, these significant changes were made:

  • A new t/run/todo.t test script was added as a place for TODO tests for known unfixed bugs.

Internal Changes

  • The "sv_strftime_ints" in perlapi function is introduced. This is an enhanced version of "my_strftime" in perlapi, which is retained for backwards compatibility. Both are to call strftime(3) when you have the year, month, hour, etc. The new function handles UTF8ness for you, and allows you to specify if you want the possibility of daylight savings time to be considered. my_strftime never considers DST.

  • The bytes_to_utf8, bytes_from_utf8, and bytes_from_utf8_loc functions are no longer experimental.

Selected Bug Fixes

  • Fix null pointer dereference in S_SvREFCNT_dec [GH #16627].

  • Fix feature 'class' Segmentation fault in DESTROY [GH #22278].

  • Fix POSIX::strftime() [GH #22369].

Perl continues to flourish into its fourth decade thanks to a vibrant community of users and developers. The following people are known to have contributed the improvements that became Perl 5.41.1:

Chad Granum, Craig A.

The list above is almost certainly incomplete as it is automatically generated from version control history. In particular, it does not include the names of the (very much appreciated) contributors who reported issues to the Perl bug tracker.

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 perl bug database at https://github.com/Perl/perl5/issues. There may also be information at https://www.perl.org/, the Perl Home Page.

If you believe you have an unreported bug, please open an issue at https://github.com/Perl/perl5/issues. Be sure to trim your bug down to a tiny but sufficient test case.

If the bug you are reporting has security implications which make it inappropriate to send to a public issue tracker, then see "SECURITY VULNERABILITY CONTACT INFORMATION" in perlsec for details of how to report the issue.

Give Thanks

If you wish to thank the Perl 5 Porters for the work we had done in Perl 5, you can do so by running the perlthanks program:
