The major change to this release is that the really ugly monolithic getter/setter coupling that awkwardly imitated a lens has been replaced with a proper set of idiomatic, modular lenses. The code's a lot cleaner and smaller as a result, and allows the trivial implementation of some extra functions... one of which I included in the package gratis (mapLocation).
In addition to some general spring cleaning / package maintenance (updating build dependencies, removing imports rendered unnecessary by GHC 7.10), I've moved the library to BSD3.
This should make it easier for anyone looking to use the library without worrying about GPL consistency.
