It isn't entirely clear to me what the purpose of that version number 
is, i.e. what exactly we want it to capture. But in the absence of any 
more robust version scheme, I agree, we should bump it.

(A slightly improved versioning mechanism would generate the 
`version.hpp` header using something akin to `git describe --tags 
--long`, so the version would contain a mix of tagged version string and 
SHA, which allows to easily look up the commit corresponding to the 
current version. But that may be a little more involved than we have 
time for right now.)
