Actually, it is more recent (0.17.7744) than the stable version (0.16.6703). But it looks like there's a packaging problem. Also, it is old compared to the current development version available in the daily PPA. Right now, it contains the version 0.17.8317.
FYI: The first two digits after the zero define the version (0.16, 0.17), and the 4 last digits define the revision. The revision number is based on the commits in the master source code branch. A commit is a change in the source code, either to add a new feature or to fix a bug.
