4.2

• Renamed -| to ProfunctorAdjunction because GHC 7.4 still exists in the wild.
• Renamed -/-> to :-> for the same reason. Also the former was confusing as they conflated profunctor homomorphisms and profunctors themselves.

4.1

• Flipped the order of 'Procompose'
• Added the notion of Monads and Comonads on the category of profunctors.
• Added 'Cayley' which takes normal Haskell Monads and Comonads to a 'ProfunctorMonad' and 'ProfunctorComonad' respectively. Cayley is also known as the 'static arrow' construction
• Added 'Closed' which is adjoint to 'Strong'.
• Added 'Closure' which freely adjoins 'Closed' to any 'Profunctor'.
• Added 'Tambara' which freely adjoins 'Strong' to any 'Profunctor'.
• Added 'Cotambara' which freely adjoins 'Choice' to any 'Profunctor'.
• Under the new 'Procompose' the old 'Rift' is now 'Ran', and the old 'Lift' was misnamed. It is now 'Rift'
