There are even some distros that couldn’t upgrade to Linux Kernel 5.17 yet. Distribution maintainers are urged to upgrade to the 5.18 kernel series now.

Linux Kernel 5.18 was also updated to version 5.18.4. Linux Kernel 5.18 came with various important features, such as user events support in the tracing system, 64-bit integrity checksums support on NVMe devices, and improved scheduling performance on AMD Zen processors. Users or developers who don’t want to upgrade Linux Kernel frequently can switch to a long-term-support branch, such as Linux Kernel 5.15 LTS. Greg Kroah-Hartman, Linux Kernel developer said,
« This is the LAST 5.17.y kernel release. This kernel branch is now end-of-life. Please move to 5.18.y at this point in time, no more new updates will happen on this kernel branch at all. »
