Base package
The base package contains the Prelude and its support libraries, and a large collection of useful libraries ranging from data structures to parsing combinators and debugging utilities. It is specific to the GHC implementation of Haskell. It includes Arrays, Arrows, Functors, Maybe, Monads and many others.
Versions
The base package is shipped alongside the GHC compiler, and each GHC version requires that specific version of the base package. So to declare which GHC versions a cabal package builds with, you can set corresponding bounds on the base package.
But version numbers for base do not match the GHC version number. Here is a partial list of which version of the base package was shipped with each GHC release. For more details, see also
