Ubuntu 26.04 LTS “Resolute Raccoon” released with Linux 7.0

Ubuntu 26.04 LTS

Canonical has just announced the release of Ubuntu 26.04 LTS “Resolute Raccoon” Linux distribution about two years after Ubuntu 24.04 LTS “Noble Numbat” was introduced. The new version of the operating system comes with the just-released Linux 7.0 kernel, GNOME 50, and a range of updates and new features. As a long-term support release, Ubuntu 26.04 LTS will be supported for 5 years until April 2031, and an Ubuntu Pro subscription provides access to ESM (Expanded Security Maintenance) updates for ten years, or until April 2036. One of the benefits of using the latest Linux 7.0 kernel is support for Intel Core Ultra Series 3 “Panther Lake” processors, including Intel Xe3 integrated graphics and the integrated NPU (Neural Processing Unit) optimizations, which may also benefit Wildcat Lake processors (aka Panther Lake Lite). Canonical also highlights TPM-backed full-disk encryption, improved support for application permission prompting, Livepatch updates for Arm-based servers, and […]

Linux 7.0 Release – Main changes, Arm, RISC-V, and MIPS architectures

Linux 7.0

Linus Torvalds has just released Linux 7.0 on LKML: The last week of the release continued the same “lots of small fixes” trend, but it all really does seem pretty benign, so I’ve tagged the final 7.0 and pushed it out. 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. Only time will tell. Anyway, this last week was a little bit of everything: networking (core and drivers), arch fixes, tooling and selftests, and various random fixes all over the place. Let’s keep testing, and obviously tomorrow the merge window for 7.1 opens. I already have four dozen pull requests pending – thank you to all the early people. Linus This follows the Linux 6.19 release about two months ago, which brought us PCIe link encryption and […]
