Notice: If you're already having a bunch of kernel-packages downloaded before this update, then you must re-download them since those won't be able to properly update kernel unless you're using DarkMatter. (All the kernel-pkgs have been rebuild & re-uploaded)
How to update ?

This update is mainly focused in stability and as much bug-fixes as possible.
