CONTENTS

NAME

perldelta - what is new for perl v5.35.6

DESCRIPTION

This document describes differences between the 5.35.5 release and the 5.35.6 release.

If you are upgrading from an earlier release such as 5.35.4, first read perl5355delta, which describes differences between 5.35.4 and 5.35.5.

Core Enhancements

use v5.36 now disables bareword_filehandles, indirect, and multidimensional

The :5.36 bundle, loaded by use v5.36, no longer includes bareword_filehandles, indirect, or multidimensional meaning that these discouraged forms of syntax will not be allowed within the scope of that version declaration.

This will also affect use v5.35.x, even on subversions of v5.35 prior to this one.

Modules and Pragmata

Updated Modules and Pragmata

Testing

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

Platform Support

Discontinued Platforms

DOS/DJGPP

DJGPP is a port of the GNU toolchain to 32-bit x86 systems running DOS. The last known attempt to build Perl on it was on 5.20, which only got as far as building miniperl.

AT&T UWIN

UWIN is a UNIX compatibility layer for Windows. It was last released in 2012 and has been superseded by Cygwin these days.

Selected Bug Fixes

Obituary

David H. Adler (DHA) passed away on November 16, 2021. In 1997, David co-founded NY.pm, the first Perl user group, and in 1998 co-founded Perl Mongers to help establish other user groups across the globe. He was a frequent attendee at Perl conferences in both North America and Europe and well known for his role in organizing Bad Movie Night celebrations at those conferences. He also contributed to the work of the Perl Foundation, including administering the White Camel awards for community service. He will be sorely missed.

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.
