The Maintainers Summit is a one-day, invitation-only gathering of about 30 kernel developers; it is held once each year to discuss policy-related issues that are not always amenable to resolution via email. The 2026 event was scheduled for October 8 in Prague, Czechia. Unsurprisingly, the discussion there was dominated by large language models (LLMs) and their effect on the development community, but some time was also found to talk about security bugs and long-term succession planning.

The LineageOS project, which produces an Android-based distribution for mobile devices, has announced the release of LineageOS 24.0. We're a bit sentimental about this release, as it precedes a really fun upcoming milestone. On December 24, 2026, LineageOS will celebrate 10 years. It's a remarkable milestone for a project built by a passionate community of developers, maintainers, contributors, and users who have kept so many devices alive along the way. [...] We've been hard at work rebasing a…

The 7.3-rc7 kernel prepatch is out for testing. According to Linus: " As always, I would have preferred to see a smaller rc, but it's not like anything in here looks like a reason to delay the final release. So that's still set for next weekend unless something new comes up. " One notable change that slipped into the mainline this week is the deprecation of the ext4 data=journal mode; it will be removed entirely at the beginning of 2028.

The 7.2.10 and 6.18.56 stable kernels have been released. Each contains another several hundred important fixes.

Version 3.15 of the Python programming language has been released. Notable changes in this release include the addition of the sentinel and frozendict built-in types, the use of UTF-8 encoding by default, package start-up configuration files , as well as improvements in the experimental JIT compiler . See the " What's new in Python 3.15 " article for an in-depth look at new features in this release, and the changelog for a full list of changes.

While many developers are struggling to keep up with the flood of vulnerability reports, others are still focused on preventing those reports from happening in the first place. Control-flow integrity (CFI) is the term for preventing (or at least detecting) exploits that divert the flow of control from its intended paths. At the 2026 GNU Tools Cauldron , Kees Cook presented his changes to the GCC compiler suite to support forward-edge CFI for the kernel.

At the 2026 All Systems Go! conference, systemd maintainers Luca Boccassi and Zbigniew Jędrzejewski-Szmek delivered the traditional "state of the project" session with an overview of the systemd project's accomplishments in the past year. That was followed by a maintainer round table where Boccassi, Jędrzejewski-Szmek, Daan De Meyer, and project leader Lennart Poettering fielded questions about systemd's size, health, and if it might replace Kubernetes. (It will not.)

Let's Encrypt , the nonprofit that provides free TLS certificates for millions of sites, has announced that it will be moving to certificates with 64-day lifetimes on February 10, 2027: This means that any certificate we issue or renew on and after that date will have a 64 day validity period, and we expect the last 90-day certificate to expire on May 11, 2027. We will not revoke valid certificates as a part of this process. This is the second stage of Let's Encrypt's plan, announced in 2025 , …

Tomáš Šedovič is a program manager at the Rust Foundation. He co-leads the goals team , which helps organize the Rust project's overall goals , including making sure that the people who have agreed to work on one have the support they need. At Kangrejos 2026, he provided an overview of the Rust project's goal processes aimed at ensuring that the Rust for Linux developers were aware of how the project organizes, tracks, and amends goals. The Rust for Linux project has inspired several current pr…

The kernel's swap layer has undergone some significant changes over the course of the last year and a number of longstanding problems have been addressed. One problem that has not yet been solved in the mainline is the direct tie between slots in the swap cache and space in persistent swap files, which can cause highly inefficient resource use. There are two competing solutions for this problem, neither of which has, as yet, reached readiness for merging; a lengthy discussion on possible paths …

Nadrieril is a long-time Rust contributor, and the maintainer of the rustc pattern-matching infrastructure. During his involvement with Rust, he has noticed a problem with the usability of the language: it is difficult to automatically extract information from a Rust crate for use with other tooling. The Charon project aims to fix that by providing a stable API for accessing internal information from the Rust compiler.
