In May Linux finally saw the release of kernel version 3.0 , an evolutionary update to the popular open-source platform that was nearly 15 years in the making. Today, version 3.1 is making its debut, once again primarily offering small tweaks like better support for Intel's Ivy Bridge and Cedar Trail chips and improved power management. But there are some new features getting baked in, including support for NFC and drivers for Wiimotes. The brave amongst you can download the sources from Git now (it hasn't been posted to Kernel.org just yet), but we suggest you hold out until your distro of choice releases an official update.
