ZDNET’s key takeaways
- The brand new kernel’s quantity ends in zero, however 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 “near operating out of fingers and toes,” he’d determined that as a substitute of three.20, he’d use 4.0 for the following launch.
Now, he is launched Linux 7.0, successor to Linux 6.19, for a similar purpose. If somebody tells you that 7.0 is a “main” launch, they’re improper. It is a good launch with some important modifications, however it’s not a “massive” one.
Rust is native finally
That mentioned, Rust has lastly turn 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 many assembled builders is that Rust within the kernel is now not experimental — it’s now a core a part of the kernel and is right here to remain. So the ‘experimental’ tag will probably 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, equivalent to Canonical’s Ubuntu, are incorporating Rust into Linux as rapidly as they will. As Jon Seager, VP of engineering for Ubuntu, informed me final fall, Canonical will probably be changing key system parts with Rust-based alternate options to reinforce security and resilience.
One other vital enchancment in 7.0 is a revamped scheduler that permits lazy preemption by default. The revised scheduler will optimize efficiency on hybrid CPU architectures equivalent 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 underneath combined compute hundreds, significantly when operating containerized workloads in cloud environments.
In a associated change, Time-Slice Extension (TIP) is now baked in. In the event you’re a Linux desktop and gaming consumer, you will recognize its results.
Maybe probably the most attention-grabbing change in 7.0 is not within the Linux code itself, however within the Linux developer group’s adoption of AI. As Torvalds mentioned in his 7.0 launch notes, “I believe it is lots of AI device use that may maintain discovering nook instances for us for some time, so this can be the ‘new regular’ at the least 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 a substitute of AI drowning maintainers with AI slop, “One thing occurred and the world switched. Now now we have actual studies.” It isn’t simply Linux, he added. “All open-source initiatives have actual studies which might be made with AI, however they’re good, they usually’re actual.”
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), ship us higher safety bug studies as the amount of studies these previous few weeks has elevated dramatically as a result of instruments getting higher at discovering issues.”
Clearly, AI has turn into a part of the Linux toolbox.
Tips on how to strive Linux 7.0 right this moment
Sounds attention-grabbing? Wish to give 7.0 a strive? Nicely, you are able to do it the laborious approach by pulling the 7.0 repository and compiling the kernel your self. No, actually! It isn’t that tough.
To illustrate 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 newest kernel as quickly as potential.
The next distros have already got 7.0 out there: 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, fashionable Ubuntu-derived distributions equivalent to Linux Mint and Pop!_OS 26.04 will roll it out — Arch Linux’s relative Manjaro.
Take into accout, 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 way in which. However, in case you like residing on Linux’s bleeding edge, it is definitely worth the hassle. Take pleasure in!
