Besides the logo, some of the new important features are:
- Support for kernel mode-setting on Intel hardware. “Mode setting” is for setting up things like screen resolution and depth mode, in other words, configuring whatever is necessary on the graphics card for displaying things on the screen.
- Btrfs: is the next-generation Linux filesystem, developed from scratch following the design principles of filesystems like ZFS, WAFL, etc.
- Squashfs: is a highly compressed read-only filesystem that is well know for being used in the Live-CDs of the most common Linux distributions and embedded distributions for some routers.
- Support for WiMAX, a telecommunication technology that provides wireless transmission of data using a variety of transmission modes. It can make up to 75 Mbit/s symmetric broadband speed.
- Wireless Access Point mode support. The mac80211 wifi stack is now ready to support AP mode.
- eCryptfs implements transparent encryption of a file.
Here is the full change list.
