Linus Torvalds has released Linux 2.6.34. In brief "This version adds two new filesystem, the distributed filesystem Ceph and LogFS, a filesystem for flash devices. Other features are a driver for almost-native KVM network performance, the VMware ballon driver, the "kprobes jump" optimization for dynamic probes, new perf features (the "perf lock" tool, cross-platform analysis support), support for GPU switching, several Btrfs improvements, RCU lockdep, Generalized TTL Security Mechanism (RFC 5082) and private VLAN proxy arp (RFC 3069) support, asynchronous suspend/resume, several new drivers and many other small improvements."
I'm sure you as end use do not care about all that stuff :). Therefore, I would like to pick what I see is important for end user in this release.
