Summary: This release features as the most important change the merge of kernel code from the Android project. But there is more, it also includes support for a new architecture (TI C6X), much improved balancing and the ability to restripe between different RAID profiles in Btrfs, and several network improvements: a virtual switch implementation (Open vSwitch) designed for virtualization scenarios, a faster and more scalable alternative to the "bonding" driver, a configurable limit to the transmission queue of the network devices to fight bufferbloat, a network priority control group and per-cgroup TCP buffer limits. There are also many small features and new drivers and fixes are also available.
1. Prominent features in Linux 3.3
1.1. Android merge
For a long time, code from the Android project has not been merged back to the Linux repositories due to disagreement between developers from both projects. Fortunately, after several years the differences are being ironed out. Various Android subsystems and features have already been merged, and more will follow in the future. This will make things easier for everybody, including the Android mod community, or Linux distributions that want to support Android programs.
1.2. Btrfs: restriping between different RAID levels, improved balancing, improved debugging tools
1.3. Open vSwitch
1.4. Better bonding of network interfaces: teaming
1.5. Bufferbloat fighting: Byte queue limits
1.6. Per-cgroup TCP buffer limits
1.7. Network priority control group
1.8. Better ext4 online resizing
1.9. New architecture: TI C6X
1.10. EFI boot support
2. Driver and architecture-specific changes
3. Various core changes
4. Memory Management
5. File systems
6. Networking
7. Virtualization
8. Crypto
9. Security
10. Tracing/profiling
