ZDNET's cardinal takeaways
- The caller kernel's number ends successful zero, but it's not a milestone release.
- Linux 7.0 boasts improvements successful Rust, its scheduler - and it's further embracing AI.
- More than half a twelve distros will fto you effort retired Linux 7.0 now.
Once upon a clip -- successful 2015, to beryllium precise -- Linux creator Linus Torvalds grew sick and tired of long, confusing Linux kernel type numbers. Since he was "close to moving retired of fingers and toes," he'd decided that alternatively of 3.20, he'd usage 4.0 for nan adjacent release.

Now, he's released Linux 7.0, successor to Linux 6.19, for nan aforesaid reason. If personification tells you that 7.0 is simply a "major" release, they're wrong. It's a bully merchandise pinch immoderate important changes, but it's not a "big" one.
Rust is autochthonal astatine last
That said, Rust has yet go a unchangeable portion of Linux pinch this merchandise aft much than five years of statement and incremental work. At nan invitation-only Linux Kernel Maintainers Summit in Tokyo successful December 2025, Linux kernel developer Jonathan Corbet wrote, "The statement among nan assembled developers is that Rust successful nan kernel is nary longer experimental -- it is now a halfway portion of nan kernel and is present to stay. So nan 'experimental' tag will beryllium coming off."
Specifically, successful 7.0, nan kernel's build tooling now recognizes Rust modules natively, pinch afloat cross-compilation support for x86_64, ARM, and RISC-V chips.
Indeed, immoderate Linux distro vendors, specified arsenic Canonical's Ubuntu, are incorporating Rust into Linux arsenic quickly arsenic they can. As Jon Seager, VP of engineering for Ubuntu, told maine past fall, Canonical will beryllium replacing cardinal strategy components pinch Rust-based alternatives to heighten information and resilience.

Another important betterment successful 7.0 is simply a revamped scheduler that enables lazy preemption by default. The revised scheduler will optimize capacity connected hybrid CPU architectures specified arsenic Intel's Alder Lake and ARM's big.LITTLE processors. In addition, nan caller "adaptive scheduling domains" system dynamically balances halfway workloads to trim latency while improving artillery life and thermal ratio connected mobile platforms. Server operators will spot tangible improvements successful throughput nether mixed compute loads, peculiarly erstwhile moving containerized workloads successful unreality environments.
In a related change, Time-Slice Extension (TIP) is now baked in. If you're a Linux desktop and gaming user, you'll admit its effects.
Perhaps nan astir absorbing alteration successful 7.0 isn't successful nan Linux codification itself, but successful nan Linux developer community's take of AI. As Torvalds said successful his 7.0 merchandise notes, "I fishy it's a batch of AI instrumentality usage that will support uncovering area cases for america for a while, truthful this whitethorn beryllium nan 'new normal' astatine slightest for a while." In different words, we'll spot galore much AI contributions coming to Linux soon.
This sentiment is echoed by Greg Kroah-Hartman, maintainer of nan Linux unchangeable kernel, who told maine precocious that alternatively of AI drowning maintainers pinch AI slop, "Something happened and nan world switched. Now we person existent reports." It's not conscionable Linux, he added. "All open-source projects person existent reports that are made pinch AI, but they're good, and they're real."

Kroah-Hartman added that he's made immoderate archiving updates to nan "security-bugs.rst record to hopefully show nan AI devices (and immoderate users that really publication nan documentation), how to nonstop america amended information bug reports arsenic nan amount of reports these past fewer weeks has accrued dramatically owed to devices getting amended astatine uncovering things."
Clearly, AI has go portion of nan Linux toolbox.
How to effort Linux 7.0 today
Sounds interesting? Want to springiness 7.0 a try? Well, you tin do it nan difficult measurement by pulling nan 7.0 repository and compiling nan kernel yourself. No, really! It's not that hard.
Let's opportunity you're not that hard-core a Linux personification yet. You tin still footwear 7.0's tires by utilizing 1 of nan distributions that make a constituent of releasing versions pinch nan latest kernel arsenic soon arsenic possible.

The pursuing distros already person 7.0 available: Arch Linux, openSUSE Tumbleweed, Gentoo, NixOS (unstable), Fedora Rawhide, and Ubuntu 26.04 LTS (beta/rc). In nan adjacent fewer weeks, you'll besides spot it successful Fedora 44 and Ubuntu 26.04. After that, celebrated Ubuntu-derived distributions specified arsenic Linux Mint and Pop!_OS 26.04 will rotation it retired -- Arch Linux's comparative Manjaro.
Keep successful mind, though, that while 7.0 is retired now, it's besides brand-spanking new. You tin beryllium judge you'll tally into immoderate glitches on nan way. But, if you for illustration surviving connected Linux's bleeding edge, it's worthy nan trouble. Enjoy!
