Linux kernel 5.7 was announced at the end of May 2020 and it shipped with some interesting features, including a new and improved exFAT file system, ARM Kernel Pointer Authentication for the ARM64 (AArch64) architecture, as well as several new features to optimize certain x86 CPUs, such as frequency invariant scheduler accounting and split lock detection. But Linux kernel 5.7 is one of those short-lived kernel branches and it’s now marked as EOL (End-of-Life) on the kernel.org website, starting today with the release of the last maintenance update in the series, Linux kernel 5.7.19. Therefore, if you’re using a GNU/Linux distribution powered by the Linux 5.7 series, you should upgrade to Linux kernel 5.8 as soon as possible.
