ZDNET’s key takeaways
- The brand new kernel’s quantity ends in zero, nevertheless it’s not a milestone launch.
- Linux 7.0 boasts enhancements in Rust, its scheduler – and it is additional embracing AI.
- Greater than half a dozen distros will allow you to check out Linux 7.0 now.
As soon as upon a time — in 2015, to be exact — Linux creator Linus Torvalds grew sick and bored with lengthy, complicated Linux kernel model numbers. Since he was “close to running out of fingers and toes,” he’d determined that as an alternative of three.20, he’d use 4.0 for the following launch.
Additionally: France is changing 2.5 million Home windows desktops with Linux – and I mapped out its new stack
Now, he is launched Linux 7.0, successor to Linux 6.19, for a similar motive. If somebody tells you that 7.0 is a “major” launch, they’re incorrect. It is a good launch with some important modifications, nevertheless it’s not a “big” one.
Rust is native eventually
That stated, Rust has lastly develop into a steady a part of Linux with this launch after greater than 5 years of debate and incremental work. On the invitation-only Linux Kernel Maintainers Summit in Tokyo in December 2025, Linux kernel developer Jonathan Corbet wrote, “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.”
Particularly, in 7.0, the kernel’s construct tooling now acknowledges Rust modules natively, with full cross-compilation assist for x86_64, ARM, and RISC-V chips.
Certainly, some Linux distro distributors, similar to Canonical’s Ubuntu, are incorporating Rust into Linux as rapidly as they’ll. As Jon Seager, VP of engineering for Ubuntu, instructed me final fall, Canonical will likely be changing key system parts with Rust-based alternate options to boost security and resilience.

One other essential enchancment in 7.0 is a revamped scheduler that permits lazy preemption by default. The revised scheduler will optimize efficiency on hybrid CPU architectures similar to Intel’s Alder Lake and ARM’s massive.LITTLE processors. As well as, the brand new “adaptive scheduling domains” mechanism dynamically balances core workloads to cut back latency whereas enhancing battery life and thermal effectivity on cell platforms. Server operators will see tangible enhancements in throughput beneath combined compute masses, significantly when working containerized workloads in cloud environments.
In a associated change, Time-Slice Extension (TIP) is now baked in. Should you’re a Linux desktop and gaming person, you will respect its results.
Maybe essentially the most attention-grabbing change in 7.0 is not within the Linux code itself, however within the Linux developer neighborhood’s adoption of AI. As Torvalds stated in his 7.0 launch notes, “I suspect it’s a lot of AI tool use that will keep finding corner cases for us for a while, so this may be the ‘new normal’ at least for a while.” In different phrases, we’ll see many extra AI contributions coming to Linux quickly.
This sentiment is echoed by Greg Kroah-Hartman, maintainer of the Linux steady kernel, who instructed me just lately that as an alternative of AI drowning maintainers with AI slop, “Something happened and the world switched. Now we have real reports.” It isn’t simply Linux, he added. “All open-source projects have real reports that are made with AI, but they’re good, and they’re real.”
Additionally: I attempted a command-line-only distro that may significantly enhance your Linux expertise
Kroah-Hartman added that he is made some documentation updates to the “security-bugs.rst file to hopefully tell the AI tools (and any users that actually read the documentation), how to send us better security bug reports as the quantity of reports these past few weeks has increased dramatically due to tools getting better at finding things.”
Clearly, AI has develop into a part of the Linux toolbox.
The way to strive Linux 7.0 immediately
Sounds attention-grabbing? Need to give 7.0 a strive? Properly, you are able to do it the exhausting method by pulling the 7.0 repository and compiling the kernel your self. No, actually! It isn’t that onerous.
For instance you are not that hard-core a Linux person but. You’ll be able to nonetheless kick 7.0’s tires through the use of one of many distributions that make some extent of releasing variations with the newest kernel as quickly as potential.
Additionally: That is my favourite Linux distro of all time – and I’ve tried all of them
The next distros have already got 7.0 accessible: Arch Linux, openSUSE Tumbleweed, Gentoo, NixOS (unstable), Fedora Rawhide, and Ubuntu 26.04 LTS (beta/rc). Within the subsequent few weeks, you will additionally see it in Fedora 44 and Ubuntu 26.04. After that, in style Ubuntu-derived distributions similar to Linux Mint and Pop!_OS 26.04 will roll it out — Arch Linux’s relative Manjaro.
Consider, although, that whereas 7.0 is out now, it is also brand-spanking new. You will be positive you will run into some glitches alongside the best way. However, if you happen to like dwelling on Linux’s bleeding edge, it is well worth the hassle. Get pleasure from!
