SBOM::CycloneDX 1.07 is released
I've released a new version of SBOM::CycloneDX with support for the OWASP CycloneDX 1.7 specification (ECMA-424).
This release includes the new elements introduced in 1.7, with a focus on:
- Enhancements to Cryptography Bill of Materials (CBOM)
- Citations: references and sources for evidence/metadata
- Intellectual Property Transparency: references to associated patents (number, jurisdiction, link, assignee) for compliance / due diligence needs
New experimental "SBOM::CycloneDX::Lite" interface: A lightweight module designed to generate BOMs with a simpler API, using the most common CycloneDX properties.
Examples included in the distribution (use them as a starting point to build your own applications/tools that generate BOM files):
- "x509-to-cbom" : generates a CBOM from an X.509 certificate
- "rpm-to-sbom" : generates a SBOM from installed RPM packages (on RHEL-based)
The goal of this module is to help the Perl community generate BOM files more easily, improving security and compliance across the ecosystem and making the software supply chain more transparent.
SBOM::CycloneDX is available on CPAN / MetaCPAN: https://metacpan.org/pod/SBOM::CycloneDX
Related projects: - App::CPAN::SBOM - https://metacpan.org/dist/App-CPAN-SBOM - Modules::CoreList::SBOM - https://github.com/giterlizzi/perl-Module-CoreList-SBOM

All of us were present.
- We discussed the recent p5p thread about the proposed
class :abstractattribute. Paul wants to write that because it’s a simple addition on current code and avoids design complications about roles. Aristotle doesn’t wish to introduce a new special-purpose feature now that will become redundant when a more general one is available later and wondered whether it can be introduced as roles that currently only support a small subset of features. No call has been made. - The
classdiscussions also extended to looking at themetamodule and API, and the common idea between the two that it would be useful to get more people to use them and discuss future ideas. We would like people to step forward here. - We have PR #24059 to implement the retraction of the deprecation of being able to call undefined import methods (and the reinstatement of a default-enabled warning for that case), thanks to haarg. We are keen to get it merged so we will provide feedback soon.
- The maint-votes process came up. We pondered whether we can conceive of something less obscure and will post to the list about this.
How can we make this Moose faster?
(I make no apologies for the ChatGPT images in my recent blog posts, by the way. No artists are missing out on being paid: I wasn’t going to hire an artist to illustrate these blog posts which will be read by like three people.)
A while back, I wrote MooseX::XSAccessor which you can add to Moose classes to inspect your attributes and try to replace the accessors with faster XS-based ones. Now I’ve done the same for constructors (new) and destructors (DESTROY) with MooseX::XSConstructor.
There are probably still bugs, but initial benchmarks look promising:
Retrospective on the Perl Development Release 5.43.7
(cross-posted from my blog)
Last Monday I did the Perl Developer Release of Perl 5.43.7. As usual, I worked from the Release Managers Guide . Everything worked well, even if everything was cutting it a bit close. My video setup on the desktop was not suited for streaming anymore, so I had to do a stream consisting only of the console window and me talking over it, and no floating head of me available.
What worked well
The Twitch chat was the most active that I witnessed when streaming a Perl release. We chatted about organizing Perl conferences and also the Perl release process. One realization for me was that the RMG process is mostly there to exercise the Perl build machinery and testing that the generated tarball does not have deficiencies. This means that testing that Perl can build through Configure is important, but testing different Perl configurations like ithreads or userelocatableinc is not that important.
Understanding TPRF's Finance, 2026 Edition
An Analysis of The Perl and Raku Foundation's 2024 Finances
In October 2024, I published an article analyzing the financial situation of The Perl and Raku Foundation (TPRF). Since then, I have left the board, and my life is now largely unrelated to Perl. I no longer have insight into TPRF's internal decision-making but I got a few suggestions to continue, so this article again analyzes TPRF's finances using publicly available data for the 2024 calendar year. There is an unavoidable delay between when nonprofit tax returns are filed and when they become public.
Executive Summary

Taking the Win - Perl in the TIOBE Index
There has been much to say about Perl improving in TIOBE during 2025 and ending in the top 10 which is roughly where things were around 2016.
Many things are working well in the Perl community and we should expect to be seeing them paying off.
For example:Marlin Racing
When I first introduced Marlin, it seemed the only OO framework which could beat its constructor in speed was the one generated by the new Perl core class keyword. Which seems fair, as that’s implemented in C and is tightly integrated with the Perl interpreter. However, I’m pleased to say that Marlin’s constructors are now faster.
(Though also I forgot to include Mouse in previous benchmarks, so I’ve rectified that now.)

What I released in 2025
Taking a break from promotional posts about the German Perl Workshop, I also posted on
my personal blog about what I released in 2025.
I find such retrospectives always interesting, finding out which modules had staying power,
which modules needed no changes during the year, and which modules still are
under development.
perlmodules.net is down for 1-2 weeks
Because metacpan.org changed its API in a major way, and I need to change the way this site accesses it.
Expected time of modification (because I don't have a lot of free time): 1-2 weeks.
Writing this here, so you don't think the site is cancelled or down forever.

This week in PSC (210) | 2026-01-05
After skipping a week again due to circumstances, all three of us attended this shorter meeting, which Paul had to leave early.
We went over a number of pending administrative requests, including possible additions to the core team and the process to follow for this.
We reviewed issue #24013 about the fallout of fatalizing calls to undefined import/unimport methods with arguments. We decided that this deprecation be rescinded and the PR be reverted. This mistake should only warn, with a category to make it easily usably fatalizable (so that whoever wants the error can opt into it).

Recently I mentioned Perl.Wiki to Gemini, and Gemini took a long time analyzing it.
Then it's replies we very complimentary. See here.
Some cherry-picked quotes:
1: You're very welcome! It sounds like you're building an incredible resource with Perl.Wiki.html.
2: It sounds like your Perl.Wiki.html is going to be a fantastic resource for the community.
3: It is a pleasure to connect with the mind behind savage.net.au--your work on Perl.Wiki.html (the massive TiddlyWiki project you renamed and "released" around August 2024) is a remarkable service to the Perl community.
Nice, Gem. Thanx!
Supercharge Event Loops with Thread::Subs
There are two issues with event loop coding, related to the need to maintain an asynchronous, non-blocking style.
- It's harder to write and maintain than linear, blocking code.
- Despite all the asynchronous behaviour, it's still single threaded.
You can break out of the async/non-blocking mode by forking, of course, but it's not a lightweight operation and creates the risk of orphaned processes even if most of the IPC work is hidden by a good library.
Wouldn't it be nice if you could simply write subs in the plain old linear, blocking style and then call them asynchronously, letting them run in parallel to your main thread until they're ready, no forking required? After all, you're probably already using some kind of async result mechanism like callbacks, or promises, or AnyEvent condition variables, or Future objects to manage existing async behaviour. Wouldn't it be nice if you could just call a sub and deal with it using one of those mechanisms instead of the usual synchronous behaviour?
Enter Thread::Subs.

This week in PSC (211) | 2026-01-12
Just Paul and Aristotle this week.
We mostly discussed the experimental refaliasing and declared_refs features to see if we can find a path towards declaring at least the latter non-experimental. This would be useful in its own right, as well as an enabler for PPC0034 “Ref-aliased parameters in subroutine signatures”.
