The KeePassXC project has recently updated its contribution policy and README to note its policy around contributions created with generative AI tools. The project's use of those tools, such as GitHub Copilot, have raised a number of questions and concerns, which the project has responded to:

There are no AI features inside KeePassXC and there never will be!

The use of Copilot for drafting pull requests is reserved for very simple and focused tasks with a small handful of changes, such as simple bugfixes or UI changes. We use it sparingly (mostly because it's not very good at complex tasks) and only where we think it offers a benefit. Copilot is good at helping developers plan complex changes by reviewing the code base and writing suggestions in markdown, as well as boilerplate tasks such as test development. Copilot can mess up, and we catch that in our standard review process (e.g., by committing a full directory of rubbish, which we identified and fixed). You can review our copilot instructions. Would we ever let AI rewrite our crypto stack? No. Would we let it refactor and rewrite large parts of the application? No. Would we ask it to fix a regression or add more test cases? Yes, sometimes.

Emphasis in the original. See the full post to learn more about the project's processes and pull requests that have been created with AI assistance.

The bootc project allows users to create a bootable Linux system image using the container tooling that many developers are already familiar with. It is an evolution of OSTree (now called libostree), which is used to create Fedora Silverblue and other image-based distributions. While creating custom images is still a job for experts, the container technology simplifies delivering heavily customized images to non-technical users.

Version 4.5 of the Mastodon decentralized social-media platform has been released. Notable features in this release include quote posts, native emoji support, as well as enhanced moderation and blocking features for server administrators. The project also has a post detailing new features in 4.5 for developers of clients and other software that interacts with Mastodon.

For those who are unaware, the Filesystem Hierarchy Standard (FHS) is the definition for POSIX operating systems to organize system and user data. It is broadly adopted by Linux, BSD, and other operating systems that follow POSIX-like conventions.

Mason Freed and Dominik Röttsches have published a document with a timeline and plans for removing Extensible Stylesheet Language Transformations (XSLT) from the Chromium project and Chrome browser:

Chromium has officially deprecated XSLT, including the XSLTProcessor JavaScript API and the XML stylesheet processing instruction. We intend to remove support from version 155 (November 17, 2026). The Firefox and WebKit projects have also indicated plans to remove XSLT from their browser engines. This document provides some history and context, explains how we are removing XSLT to make Chrome safer, and provides a path for migrating before these features are removed from the browser.

LWN covered the Web Hypertext Application Technology Working Group (WHATWG) discussion about XSLT in August.

Version 2.3.0 of the Lightweight Qt Desktop Environment (LXQt) has been released. The highlight of this release is continued improvement in Wayland support across LXQt components. Rather than offering its own compositor, the LXQt project takes a modular approach and works with several Wayland compositors, such as KWin, labwc, and niri.

Linux has many security features and tools that have evolved over the years to address threats as they emerge and security gaps as they are discovered. Linux security is all, as Lennart Poettering observed at the All Systems Go! conference held in Berlin, somewhat random and not a "clean" design. To many observers, that may also appear to be the case for systemd; however, Poettering said that he does have a vision for how all of the security-related pieces of systemd are meant to fit together. He wanted to use his talk to explain "how the individual security-related parts of systemd actually fit together and why they exist in the first place".

Version 1.3 of the Open Container Initiative (OCI) Runtime Specification has been released. The specification covers the configuration, execution environment, and lifecycle of containers. The most notable change in 1.3 is the addition of FreeBSD to the specification, which the FreeBSD Foundation calls "a watershed moment for FreeBSD":

The addition of cloud-native container support complements FreeBSD's already robust virtualization capabilities, particularly the powerful FreeBSD jails technology that has been a cornerstone of the operating system for over two decades. In fact, OCI containers on FreeBSD are implemented using jails as the underlying isolation mechanism, bringing together the security and resource management benefits of jails with the portability and ecosystem advantages of OCI-compliant containers.

Version 6.18 of the Incus container and virtual-machine management system has been released. Notable changes in this release include new configuration keys for providing credentials to systemd, BPF token delegation, VirtIO support for sound cards, the ability to export ISO volumes, improvements to the IncusOS command-line utility, and more.

Version 1.0 of the Capability Hardware Extension to RISC-V for IoT (CHERIoT) specification has been released. CHERIoT is a hardware-software system for secure embedded devices, and the specification provides a full description of the ISA and its intended use by CHERIoT RTOS. David Chisnall has written a blog post about the release that explains its significance as well as plans for CHERIoT 2.0 and beyond:

The last change that we made to the ISA was in December 2024, so we are confident that this is a stable release that we can support in hardware for a long time. This specification was implemented by the 1.0 release of CHERIoT Ibex and by CHERIoT Kudu (which has not yet had an official release). These two implementations demonstrate that the ISA scales from three-stage single-issue pipelines to six-stage dual-issue pipelines, roughly the same range of microarchitectures supported by Arm's M profile.

We at SCI have the first of our ICENI chips, which use the CHERIoT Ibex core, on the way back from the fab now and will be scaling up to mass production in the new year. I am not allowed to speak for other folks building CHERIoT silicon, but I expect 2026 to be an exciting year for the CHERIoT project!

While it remains true that KASLR should not be trusted to prevent exploitation, particularly in local contexts, it is regrettable that the attitude around Linux KASLR is so fatalistic that putting in the engineering effort to preserve its remaining integrity is not considered to be worthwhile. The joint effect of these two issues dramatically simplified what might otherwise have been a more complicated and likely less reliable exploit.

Use lazy as the keyword. We debated many of the given alternatives (and some we came up with ourselves), and ultimately agreed with the PEP's choice of the lazy keyword. The closest challenger was defer, but once we tried to use that in all the places where the term is visible, we ultimately didn't think it was as good an overall fit. The same was true with all the other alternative keywords we could come up with, so... lazy it is!

What about from foo lazy import bar? Nope! We like that in both module imports and from-imports that the lazy keyword is the first thing on the line. It helps to visually recognize lazy imports of both varieties.
