Linux Kernel 4.9 Reaches End of Life After 6 Years of Support
After being supported for a little more than six years, the Linux 4.9 kernel series has finally reached end of life with the 4.9.337 update released earlier this morning. The kernel is now marked appropriately as EOL on the kernel.org website, which means that it will no longer receive maintenance and security updates.
