Fedora contributor Simon de Vlieger has published a blog post with a walkthrough of how the project turns source code and packages into the final release that users install on their systems. It follows the a package from a packager's git push to a composed release: ISOs, cloud images, container images, and OSTree deployments. The walkthrough describes how the Fedora 'sausage' is created as of Fedora 45, things change all the time; I hope to have time to update this document every cycle or every

Greg Kroah-Hartman has announced the release of the 7.1.5 , 6.18.40 , 6.12.97 , 6.6.145 , 6.1.178 , 5.15.212 , and 5.10.261 stable Linux kernels. This batch of kernels includes a hefty set of updates, possibly the largest ever. 7.1.5-rc1 , for example, included more than 2,000 patches, 6.18.40-rc1 included 1,611 patches, and so forth. Users are advised to upgrade.

Registration is now open for the 2026 Linux Plumbers Conference, to be held October 5 to 7 in Prague, Czechia. Tickets to this event tend to sell out quickly, so interested attendees probably should not procrastinate.

On July 21, the kernel community lost Dan Williams, one of its most beloved contributors. Dave Hansen and Thomas Gleixner, both of whom worked with Williams extensively, have written an obituary and allowed LWN to publish it. He will be deeply missed, but he has left us with a lot to remember him by.

Greg Kroah-Hartman has released the 6.12.98 stable Linux kernel with a single fix for a file descriptor leak in ext4. Users of the ext4 filesystem should upgrade.

Version 2.44 of the GNU C Library has been released. Changes include a new /etc/tunables.conf file for the system-wide setting of tunable parameters, a new tunable to control the use of transparent huge pages for read-only executable segments, a number of math-function improvements, a handful of security fixes, and more.

Daniel Borkmann led a session at the 2026 Linux Filesystem, Memory-Management, and BPF Summit about the progress that has been made with netkit, the subsystem that allows virtual machines (VMs) running on Linux to perform networking efficiently. When that did not fill the full time, he went on to discuss his idea for using BPF to live-patch user-space applications. While netkit is making progress, and can now support zero-copy receipt of packets into a VM in a network namespace, the idea of usin

The Open Home Foundation , which governs the Home Assistant home-automation project, has announced the "public preview" of its Device Database : Providing a public, open way to browse the anonymous, aggregated device data we collect was always part of the plan, and this preview is our first step toward it. You can already use it to search and filter devices to see aggregated community insights, starting with a deliberately focused set of specifics, such as whether a device requires an internet c

I have just received the shocking news that Dan Williams, a longtime, high-profile kernel developer, has passed away. I knew him primarily through his long service on the Linux Foundation Technical Advisory Board; he was always a strong, thoughtful, and intelligent presence. Dan will be deeply missed. There is a support effort underway for Dan's family as they come to terms with this loss.

One of the ideas raised at the 2026 Linux Storage, Filesystem, Memory Management, and BPF Summit (LSFMM+BPF) was the creation of an operations structure for the swap subsystem. Like many parts of the kernel, the swap layer evolved over time, with pieces being added as needed; the end result of this evolution is rarely what one would expect had the subsystem been designed today. The interface between the swap layer and the devices it uses is just one example. It appears that one result of the swa

The Codeberg forge has adopted a pair of new policies, promising not to use hosted projects to train LLMs and, more controversially, banning the hosting of LLM-generated software. The site's blog describes and justifies these policies. Although often well intentioned, sharing the result of a prompt and calling it "libre software" does not make the world a better place. Codeberg is not and does not want to be a place to dump such generated single-use software that no one else will ever look at. W

One of the features that users often miss when moving from X11 to Wayland is the ability to save and restore the position of windows between sessions. At GUADEC 2026 , held in A Coruña, Spain, Adrian Vovk provided an overview of work that has gone into providing a platform-wide save and restore framework for GNOME. After two failed attempts at landing an API, he believes that the third try will be the one to succeed—though not in time for the upcoming GNOME 51 release due in October.

Python Software Foundation security developer-in-residence Seth Larson has announced that the Python Package Index (PyPI) will now reject new files that are uploaded to releases older than 14 days. The restriction is to prevent the poisoning of old releases if publishing tokens or workflows of PyPI projects are compromised. The discussion of this behavior began during PEP 740 (Digital Attestations) back in January 2024. The discussion was restarted in March 2026 after the popular packages LiteLL

Tracepoints in the kernel are useful for a variety of purposes: debugging, active monitoring, and performance measurements, among other things. Previously, any given BPF program could only be attached to a single tracepoint. Jiri Olsa has been working to change that, and led a discussion about his progress at the 2026 Linux Storage, Filesystem, Memory-Management, and BPF Summit . That work has since been merged , and can be expected as part of the 7.2 kernel.

Version 153.0 of the Firefox web browser has been released. Notable changes in this release include a change to the default local-file-access permissions for extensions, enabling LAN restrictions by default for all users, a visual indicator when a web site has access to the user's location, the ability to merge PDFs and add images as pages within PDFs, as well as experimental support for the JPEG XL image format. See the release notes for developers for all changes that affect web developers, an

Like many development communities, the kernel community has been struggling to determine how large language models will be used in its development process. The news has been dominated recently by a strongly worded missive from Linus Torvalds on the subject, but the discussion has been rather more wide-ranging and nuanced than that. Topics that have been considered recently include the LLM attribution requirement, code-review tools, dependence on proprietary tools, and whether there is a place fo
