# NAME

perl5397delta - what is new for perl v5.39.7

# DESCRIPTION

This document describes differences between the 5.39.6 release and the 5.39.7 release.

If you are upgrading from an earlier release such as 5.39.5, first read perl5396delta, which describes differences between 5.39.5 and 5.39.6.

# Modules and Pragmata

The list of new and updated modules is modified automatically as part of preparing a Perl release, so the only reason to manually add entries here is if you're summarising the important changes in the module update. (Also, if the manually-added details don't match the automatically-generated ones, the release manager will have to investigate the situation carefully.)

## Updated Modules and Pragmata

- Exporter has been upgraded from version 5.77 to 5.78.

- Hash::Util has been upgraded from version 0.30 to 0.31.

- I18N::Langinfo has been upgraded from version 0.22 to 0.23.

  It now handles the additional locale categories that Linux defines beyond those in the POSIX Standard.

- Math::BigInt has been upgraded from version 2.003001 to 2.003002.

- Math::BigInt::FastCalc has been upgraded from version 0.5016 to 0.5018.

- Pod::Checker has been upgraded from version 1.75 to 1.76.

- SelfLoader has been upgraded from version 1.26 to 1.27.

# 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.

# Internal Changes

- `dAX`, `dITEMS` and hence `dXSARGS` now declare `AX` and `items` as `Stack_off_t` rather than `SSize_t`. This reverts back to compatibility with pre-64-bit stack support for default builds of perl where `Stack_off_t` is `I32`. [GH #21782]

- A new function is now available to `XS` code, "sv_langinfo" in perlapi. This provides the same information as the existing "Perl_langinfo8" in perlapi, but returns an SV instead of a `char *`, so that programmers don't have to concern themselves with the UTF-8ness of the result. This new function is now the preferred interface for `XS` code to the nl_langinfo(3) `libc` function. From Perl space, this information continues to be provided by the I18N::Langinfo module.

# Known Problems

- Windows test failures

  Some tests fail on Windows. This needs further investigation.

      Test Summary Report
      -------------------
      ../cpan/Win32/t/GetFolderPath.t
        Failed test:  1
      ../cpan/Win32API-File/t/file.t
        Failed test:  41
      ../ext/XS-APItest/t/locale.t
        Non-zero exit status: 5
        Parse errors: No plan found in TAP output

- perlivp is missing streamzip

  The `streamzip` utility does not get installed on Windows but should get installed.

# Acknowledgements

Perl 5.39.7 represents approximately 3 weeks of development since Perl 5.39.6 and contains approximately 7,300 lines of changes across 160 files from 16 authors.

Excluding auto-generated files, documentation and release tools, there were approximately 5,600 lines of changes to 79 .pm, .t, .c and .h files.

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 5.39.7:

Craig A. Berry, Dagfinn Ilmari Mannsåker, David Mitchell, Elvin Aslanov, H.Merijn Brand, James E Keenan, Karen Etheridge, Karl Williamson, Mathias Kende, Max Maischein, Peter John Acklam, Philippe Bruhat (BooK), Todd Rinaldo, Tony Cook, Yves Orton, Дилян Палаузов.

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.

For a more complete list of all of Perl's historical contributors, please see the AUTHORS file in the Perl source distribution.

# 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 http://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:

    perlthanks

This will send an email to the Perl 5 Porters list with your show of thanks.
