Linux Kernel developer Greg Kroah-Hartman has announced that Linux Kernel 5.1 has reached the end of its life, recommending users to upgrade to Linux Kernel 5.2 series.
Announced in early May, Linux Kernel 5.1 comes with the ability to use persistent memory as RAM, as well as support for starting the device mapper without using initramfs, support for cumulative patches in the livekernel, and many other preparations for 2038.
Additionally, Linux Kernel 5.1 introduced support for configuring Zstd compression levels on the Btrfs file system, faster and more scalable asynchronous I / O, power manager improvements, scalable monitoring for large file systems, as well as Updated drivers for hardware support.
Now, Linux Kernel 5.1 has reached the end of its development cycle with the 5.1.21 update released by Greg Kroah-Hartman earlier this week. Therefore, users are advised to upgrade to the new series, Linux Kernel 5.2.
If you are using Linux Kernel 5.1 in your distribution, you should upgrade to Linux Kernel 5.1.21 as soon as possible or upgrade to the new Linux Kernel 5.2 series, the latest series so far.
To update to Linux Kernel 5.2 you will have to investigate if the developer of your distribution has already put the packages in the stable repositories, if he has not done so, another option is to compile the kernel from yourself using the official page.
