This is your friendly reminder that, as of today, the Linux 6.17 kernel series has reached the end of its supported life, which means that it’s time to start upgrading your installations to Linux kernel 6.18 LTS.

Released on September 28th, 2025, Linux kernel 6.17 introduced new features like support for ARM’s “Branch Record Buffer Extension” (BRBE), support for the AMD hardware feedback interface (HFI), Intel Wildcat Lake and Bartlett Lake-S support, and initial support for the HEVC(H.265) and VP9 codecs in Qualcomm’s Iris decoder.

Since Linux 6.17 is a short-lived kernel branch, supported for a couple of months, it is now marked as EOL (End of Life) on the kernel.org website by Linux kernel developer Greg Kroah-Hartman, who announced today the last maintenance release, Linux kernel 6.17.13, urging users to upgrade to Linux kernel 6.18.
