As of today, Linux kernel 6.15 has officially reached its end of life. This means users should promptly consider upgrading to the newly released Linux kernel 6.16. Kernel 6.15, which debuted on May 25, 2025, brought several enhancements, including Rust support for hrtimer and ARMv7, a new setcpuid= boot parameter for x86 CPUs, and improvements for Intel and AMD PMU. However, since it is not a long-term support (LTS) branch, it has now been designated as EOL on the kernel.org website.
The last maintenance release for 6.15, version 6.15.11, was released today by prominent kernel developer Greg Kroah-Hartman. He is encouraging users to upgrade to Linux kernel 6.16, which became available on July 28, 2025. This new version includes exciting features such as initial support for Intel Trusted Domain Extensions, USB audio offload support, and enhancements for memory allocation.
Linux kernel 6.16 has already been integrated into the stable repositories of popular distributions, including openSUSE Tumbleweed and Arch Linux, and is set to be adopted shortly by others, such as Fedora Linux. However, it’s important to note that kernel 6.16 is also a short-lived release. For users seeking long-term support, alternatives such as Linux kernel 6.12 LTS, which is the default in Debian 13 “Trixie,” or other LTS versions like 6.6 and 6.1, are recommended.
