The topic of the Rust experiment was just discussed at the annual Maintainers Summit. The consensus among the assembled developers is that Rust in the kernel is no longer experimental — it is now a core part of the kernel and is here to stay. So the "experimental" tag will be coming off. Congratulations are in order for all of the Rust for Linux team.

(Stay tuned for details in our Maintainers Summit coverage.)

The Free Software Foundation has announced the recipients of its 2024 (even though 2025 is almost over) Free Software Awards. Andy Wingo won the award for the advancement of free software, Alx Sa is the outstanding new free-software contributor, and Govdirectory takes the award for projects of social benefit.

As has been recently announced, nominations are open for the 2025 Linux Foundation Technical Advisory Board (TAB) elections. I am one of the TAB members whose term is coming to an end, but I have decided that, after 18 years on the board, I will not be seeking re-election; instead, I will step aside and make room for a fresh voice. My time on the TAB has been rewarding, and I will be sad to leave; the TAB has an important role to play in the functioning of the kernel community.

As of this writing, 4,124 non-merge commits have been pulled into the mainline repository for the 6.19 kernel development cycle. That is a relatively small fraction of what can be expected this time around, but it contains quite a bit of significant work, with changes to many core kernel subsystems. Read on for a summary of the first part of the 6.19 merge window.

Version 2025.12 of the Home Assistant home-automation system has been released.

This month, we're unveiling Home Assistant Labs, a brand-new space where you can preview features before they go mainstream. And what better way to kick it off than with Winter mode? ❄️ Enable it and watch snowflakes drift across your dashboard. It's completely unnecessary, utterly delightful, and exactly the kind of thing we love to build. ❄️

But that's just the beginning. We've been working on making automations more intuitive over the past releases, and this release finally delivers purpose-specific triggers and conditions. Instead of thinking in (numeric) states, you can now simply say "When a light turns on" or "If the climate is heating". It's automation building the way our mind works, as it should be.
