Software Update: Linux Kernel 3.15

Version 3.15 of the Linux Kernel has been released. The kernel is the heart of the operating system and, simply put, it sits as a layer between the hardware and the applications. New in version 3.15 is, among other things, that systems equipped with a hard disk are more quickly available from hibernation and that 64-bit kernels can now boot from a 32-bit efi. More information about the improvements in this release can be found at Kernel newbies and Phoronix.
