- Tons of staging driver changes.
- Support has been dropped for the old i386 CPUs to reduce the complexity of the Linux kernel.

- In certain workloads, the Linux kernel now goes through a lot less system memory.
- Linux support for the Microsoft Windows 8 multi-touch protocol.
- Audio driver improvements, including new sound card drivers.
