Today we are rolling out a MetaCPAN Bootstrap 3 to Bootstrap 5 migration. After that, if the stars align, we can move on to dark mode.

Bug reports can go to https://github.com/metacpan/metacpan-web/pull/3614

I did a lot of UAT, but I imagine there will still be a number of issues that will come up, especially for mobile devices.

Perl 5.40.4 and 5.42.2 are now available.

https://metacpan.org/release/SHAY/perl-5.40.4/
https://metacpan.org/release/SHAY/perl-5.42.2/

Next Toronto.pm is on May 28. Our speaker will be @yenzie@ack.nerdfight.online and if you haven't heard him speak, I can say with confidence it's a real treat. You can sign up as of right now. If you're not sure if you can make, sign up anyway.

Got more free storage credits from Backblaze today for MetaCPAN. 🙏

We will likely be using that to store snapshots of our BackPAN (CPAN archive + deleted files).

This can't be good.

My hobby is aggregating all of the world’s swim, bike and run events. Create your own custom race calendar and easily submit new events and organizations to the index. It’s like Wikipedia for endurance events.

I have been chatting with HeroDevs about Perl 5's deprecation and versioning policies. They're not a secret, but it was also hard for me to find a concise, official summary. Not saying it's not there, but seems like it's not in an obvious place. Here's a proposal to put that clarified text into perlpolicy.pod

A new episode of The Underbar is out. I wonder if we'll soon be recording something in person? 🤔

"Olaf Kolkman has had a long career in networking and Open Source that led him to be working on Internet Technology, Policy and Advocacy at the Internet Society. In September 2025, we had a long conversation with him.

In this first part, we discussed his involvement with Perl, DNSSEC and NLnet Labs."

Just over a year ago, we launched a new logo for Perl. Now you can get it on a t-shirt, with some proceeds going back to The Perl and Raku Foundation.

"Perl has served us quite well since Fastmail’s inception. We’ve built up a large code base that has continued to work, grow, and improve over twenty years. We’ve stuck with Perl because Perl stuck with us: it kept working and growing and improving, and very rarely did those improvements require us to stop the world and adapt to onerous changes."

Thanks to @rjbs@social.semiotic.systems and Fastmail for supporting Perl 5 core development. 🙏

A big thank you to Ervin Ruci and Geolytica for sponsoring MetaCPAN once again this year. There are real expenses involved with keeping this service up and running and these contributions make a massive difference.

I'd like to add another two or three sponsors to the footer in order to keep things moving forward. If you're interested or if you can send me an introduction to a potential sponsor, I'd very much appreciate it.

This is our largest gift of 2025 and it will advance some very important work in the Perl 5 core. I'd like to thank Joseph Jerome, Oriol Soriano and Gabriel Weinberg for their support in making this happen. It's a big deal for us. ♥️
