ZDNET’s key takeaways
- The brand new kernel’s quantity ends in zero, but it surely’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 subsequent launch.

Now, he is launched Linux 7.0, successor to Linux 6.19for a similar motive. If somebody tells you that 7.0 is a “main” launch, they’re improper. It is a good launch with some vital modifications, but it surely’s not a “huge” one.
Rust is native eventually
That mentioned, Rust has lastly turn out to be a steady a part of Linux with this launch after greater than five 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 many assembled builders is that Rust in the kernel is no longer experimental — it’s now a core a part of the kernel and is right here to remain. So the ‘experimental’ tag can be coming off.”

Particularly, in 7.0, the kernel’s construct tooling now acknowledges Rust modules natively, with full cross-compilation help for x86_64, ARM, and RISC-V chips.
Certainly, some Linux distro distributors, akin to Canonical‘s Ubuntuare incorporating Rust into Linux as rapidly as they will. As Jon Seager, VP of engineering for Ubuntu, informed me final fall, Canonical will be replacing key system components with Rust-based alternatives to boost security and resilience.

One other essential enchancment in 7.0 is a revamped scheduler that allows lazy preemption by default. The revised scheduler will optimize efficiency on hybrid CPU architectures akin to Intel’s Alder Lake and ARM’s huge.LITTLE processors. As well as, the brand new “adaptive scheduling domains” mechanism dynamically balances core workloads to scale back latency whereas enhancing battery life and thermal effectivity on cellular platforms. Server operators will see tangible enhancements in throughput underneath blended compute hundreds, 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 consumer, you will admire its results.
Maybe essentially the most attention-grabbing change in 7.0 is not within the Linux code itself, however within the Linux developer community’s adoption of AI. As Torvalds mentioned in his 7.0 launch notes, “I believe it is loads of AI software use that may maintain discovering nook circumstances for us for some time, so this can be the ‘new regular’ a minimum of for some time.” 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 informed me just lately that as an alternative of AI drowning maintainers with AI slop, “One thing occurred and the world switched. Now we’ve got actual studies.” It is not simply Linux, he added. “All open-source projects have real reports which can be made with AI, however they’re good, and so they’re actual.”
Additionally: I tried a command-line-only distro that can seriously improve your Linux skills
Kroah-Hartman added that he is made some documentation updates to the “security-bugs.rst file to hopefully inform the AI instruments (and any customers that really learn the documentation), how to send us better security bug reports as the amount of studies these previous few weeks has elevated dramatically attributable to instruments getting higher at discovering issues.”
Clearly, AI has turn out to be a part of the Linux toolbox.
The best way to attempt Linux 7.0 as we speak
Sounds attention-grabbing? Need to give 7.0 a attempt? Properly, you are able to do it the arduous manner by pulling the 7.0 repository and compiling the kernel yourself. No, actually! It is not that onerous.
As an example you are not that hard-core a Linux consumer but. You possibly can nonetheless kick 7.0’s tires by utilizing one of many distributions that make some extent of releasing variations with the most recent kernel as quickly as attainable.
Additionally: This is my favorite Linux distro of all time – and I’ve tried them all
The next distros have already got 7.0 out there: Arch Linux, openSUSE Tumbleweed, Gentoo, NixOS (unstable), Fedora Rawhideand 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, well-liked Ubuntu-derived distributions akin to Linux Mint and Pop!_OS 26.04 will roll it out — Arch Linux’s relative Manjaro.
Have in mind, although, that whereas 7.0 is out now, it is also brand-spanking new. You could be certain you will run into some glitches alongside the best way. However, in the event you like dwelling on Linux’s bleeding edge, it is definitely worth the bother. Take pleasure in!
