Linux kernel 4.15 was released the other day, on January 28, 2018, as the first series to include out-of-the-box patches for the Meltdown and Spectre security vulnerabilities, among numerous other new features and improvements, and Linux Lite users can install it on their 64-bit or 32-bit machines running either series 2.x (Beryl) or series 3.x (Citrine) of the open-source operating system, but with a warning.
