The big improvements to btrfs came in 3.12. The 3.13 changes are rather minor:
a mount option to specify the maximum delay before committing writes to storage (default 30 seconds, no maximum, warning for 300+ seconds -- make sure you have battery coverage for whatever this is set to plus a few seconds, and try not to crash...)
a mount option for emergency use that will force the rebuild of the UUID tree
userspace tools that read FIEMAP_EXTENT_SHARED can now use that on btrfs; no functionality change, really, just making the info available in the same way that ocfs2 does it.
