While the version bump to 7.0 is driven solely by Linus Torvalds' versioning preferences, with [1]Linux 7.0 there are many great changes to be found in this upcoming stable kernel version to power the likes of Ubuntu 26.04 LTS. Here is a recap of all the interesting changes with Linux 7.0.

Linux 7.0 is looking quite good from preparing for upcoming AMD and Intel hardware platforms to enabling various new device driver support and more. Plus a variety of performance optimizations showing [2]some very nice performance wins for at least some workloads and hardware . Linux 7.0 also declares the Rust for Linux effort as "here to stay", dropping of some obsolete drivers, various file-system enhancements, and a lot more to benefit Linux from small embedded and mobile devices up to large HPC/AI servers.

Linux 7.0 feature highlights and changes are looked at below and on the following page. More Linux 7.0 kernel performance benchmarking is kicking off at Phoronix.
