What is new in Linux 3.0

What is new in Linux 3.0 

Linus Torvalds, the Lead Developer on the Linux from the Linux Foundation write in a message about the new version and what is coming in this version. 

In a response on the mailing group, Linus wrote, that there may not be anything new in Linux 3.0. 

From his message: 

So what are the big changes?

NOTHING. Absolutely nothing. Sure, we have the usual two thirds driver changes, and a lot of random fixes, but the point is that 3.0 is *just* about renumbering, we are very much *not* doing a KDE-4 or a Gnome-3 here. No breakage, no special scary new features, nothing at all like that. We've been doing time-based releases for many years
now, this is in no way about features. If you want an excuse for the renumbering, you really should look at the time-based one ("20 years") instead.

Alright, jokes aside, Linux 3.0 does have some new features including Btrfs data scrubbing and automatic defragmentation, XEN Dom0 support, unprivileged ICMP_ECHO, wake on WLAN, Berkeley Packet Filter JIT filtering, a memcached-like system for the page cache, a sendmmsg() syscall that batches sendmsg() calls and setns(), a syscall that allows better handling of light virtualization systems such as containers. New hardware support has been added: for example, Microsoft Kinect, AMD Llano Fusion APUs, Intel iwlwifi 105 and 135, Intel C600 serial-attached-scsi controller, Ralink RT5370 USB, several Realtek RTL81xx devices or the Apple iSight webcam. Many other drivers and small improvements have been added.
