* **cabal** is a "package manager" for Haskell. It allows you to install libraries or extensions that other people have built. (Usually those are published at the [Hackage](http://hackage.haskell.org) web site.) Some of these are experimental and may not always work; others are quite fundamental and are almost de facto parts of what people expect in a Haskell system.
* **[Haskell Platform](https://www.haskell.org/platform)** is a standard bundle that includes a fixed version of GHC, plus fixed versions of some of the most popular libraries or extensions. This is updated once or twice a year. The current version is 2014.2.0.0, from August 2014. It includes GHC version 7.8.3.
