Linux 3.2It's a little later than originally anticipated, but Linux kernel 3.2 is finally here. As per usual, it packs a number of improvements -- most them under the hood. Perhaps most exciting are some power-saving features related to graphics drivers, which should help get those battery life issues under control in Ubuntu 12.04. Other improvements include better (and hopefully more stable) WiFi drivers and faster read access to EXT4 formatted file systems. The list of changes is pretty epic to say the least. You can find plenty more detail at the source as well as a link to download the kernel for yourself, though, we highly recommend you wait until it comes to your distro of choice on its own.
