Motivation

The Haskell Platform aims to unify Haskell development tools into a single package, consisting of a compiler, compiling tools and many standard libraries, therefore making it easier to develop and deploy full-featured Haskell-driven applications.

Packages included

Currently it consists of: * GHC, Haskell's flagship compiler * The GHC- Profiler * GHCi, GHCs

bytecode Bytecode (also called portable code or p-code) is a form of instruction set designed for efficient execution by a software interpreter. Unlike human-readable source code, bytecodes are compact numeric codes, constants, and references (norma ...

Versions

Originally, the Haskell Platform aimed at a 6-months release cycle. Starting with 7.10.2 which was released July 29, 2015, it has followed the release cycle of GHC and has since used the same version numbering scheme.

Deprecation

In 2022, the Haskell Platform was deprecated, and is no longer an actively supported or recommended way of installing Haskell.
