Frankly, "very out of date" when it is version 2.0.32 in debian testing and ubuntu current while the new, one month old version is 2.0.33 is overstated.
What are the features that are not in the debian stable package (2.0.31) or in 2.0.32 but are in the cutting edge 2.0.33 version? None of the bugs reported in the debian bug tracker seem to have been fixed by later versions!
With that said, you can make some but not all packages rolling-release with apt-pinning and using stable and sid or testing which are rolling.
