💖 PERL5341DELTA 💖

okay bestie, welcome to PERL5341DELTA — the little glow-up diary for perl v5.34.1. this is the manual page, she's part of the Perl Programmers Reference Guide, and she is serving release-notes energy. sit down, grab a strawberry, let's get into it 🍓✨

🌸 NAME 🌸

perl5341delta — what is new for perl v5.34.1

✨ DESCRIPTION ✨

So this doc is literally just the tea on what changed between the 5.34.0 release and the 5.34.1 release. that's it, that's the whole vibe.

But wait — if you're hopping in from something older, like 5.32.0, don't just start here, bestie. go read perl5340delta first, because that one covers everything between 5.32.0 and 5.34.0. otherwise you'll be missing a whole season of the show 😭

💅 Incompatible Changes 💅

Good news: there are no changes intentionally incompatible with 5.34.0. none. zero. we're not doing that to you.

BUT. if you do find something incompatible? that's not a feature, that's a bug, and we need you to report it fr fr. see "Reporting Bugs" below. 🫶

🔥 Selected Bug Fixes 🔥

👑 Acknowledgements 👑

okay this is the part where we get emotional 🥹

Perl 5.34.1 represents approximately 10 months of development since Perl 5.34.0 and contains approximately 4,600 lines of changes across 60 files from 23 authors. twenty-three. the group project ate.

Excluding auto-generated files, documentation and release tools, there were approximately 1,100 lines of changes to 18 .pm, .t, .c and .h files. look at those numbers, so satisfying ✨

Perl continues to flourish into its fourth decade thanks to a vibrant community of users and developers. and the following people are known to have contributed the improvements that became Perl 5.34.1:

Andrew Fresh, Atsushi Sugawara, Chris 'BinGOs' Williams, Dan Book, Hugo van der Sanden, James E Keenan, Karen Etheridge, Leon Timmermans, Matthew Horsfall, Max Maischein, Michiel Beijen, Neil Bowers, Nicolas R., Paul Evans, Renee Baecker, Ricardo Signes, Richard Leach, Sawyer X, Sergey Poznyakoff, Steve Hay, Tomasz Konojacki, Tony Cook, Yves Orton.

real talk though: that list above is almost certainly incomplete, because it's 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. y'all are the unsung main characters and we see you 💜

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. (this part matters, bestie — a giant repro is not it, we need the snack-sized version 🍓)

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. don't put that one on a public tracker, please 🙈

💖 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. like, literally just run it and be nice. it costs nothing and it makes people's whole day 🌸
