# NAME

perl5361delta - what is new for perl v5.36.1

# DESCRIPTION

This document describes differences between the 5.36.0 release and the 5.36.1 release.

If you are upgrading from an earlier release such as 5.35.0, first read perl5360delta, which describes differences between 5.35.0 and 5.36.0.

# Incompatible Changes

There are no changes intentionally incompatible with 5.36.0. If any exist, they are bugs, and we request that you submit a report. See "Reporting Bugs" below.

# Modules and Pragmata

## Updated Modules and Pragmata

•
  Module::CoreList has been upgraded from version 5.20220520 to 5.20230423.

# Configuration and Compilation

•
  "Configure" probed for the return type of malloc() and free() by testing whether declarations for those functions produced a function type mismatch with the implementation. On Solaris, with a C++ compiler, this check always failed, since Solaris instead imports malloc() and free() from "std::" with "using" for C++ builds. Since the return types of malloc() and free() are well defined by the C standard, skip probing for them. "Configure" command-line arguments and hints can still override these type in the unlikely case that is needed. [GH #20806 <https://github.com/Perl/perl5/issues/20806>]

# Testing

Tests were added and changed to reflect the other additions and changes in this release.

# Selected Bug Fixes

- An eval() as the last statement in a regex code block could trigger an interpreter panic; e.g.

          /(?{ ...; eval {....}; })/

  [GH #19680 <https://github.com/Perl/perl5/issues/19680>]

- An "eval EXPR" referring to a lexical sub defined in grandparent scope no longer produces an assertion failures. [GH #19857 <https://github.com/Perl/perl5/issues/19857>]
- Writing to a magic variables associated with the selected output handle, $^, $~, $=, "$-" and $%, no longer crashes perl if the IO object has been cleared from the selected output handle. [GH #20733 <https://github.com/Perl/perl5/issues/20733>]

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 <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.
