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 all of our changes and features since Android 17's release in June. Android 17's first release mainly contained iterative improvements and some UI/UX refinements, but due to our previous efforts adapting to Google's heavy refactoring over the last several versions, we were able to rebase onto Android 17's code-base faster than anticipated. Yes you read that right: We're early this year!

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.
