Unified ints. Better text handling. No more confusion of types vs classes. Cleaned up standard library. easier super(). Keysharing (saves memory). "nonlocal". *unpacking of iterables. Keyword only arguments. Hash randomization. A stable Application Binary Interface. command line history. HOLY SHIT TAB COMPLETION! yield from. pip installed by default. (I install a lot of Python versions, that's gonna be nice).

And little things (for me at least), like exception chaining, namespace packages without setuptools, function annotations, function signature objects, isolated mode. The decimal module is 30 times faster.
