data Version

A Version represents the version of a software entity.

Instances of Eq and Ord are provided, which gives exact equality and lexicographic ordering of the version number components (i.e. 2.1 > 2.0, 1.2.3 > 1.2.2, etc.).

This type is opaque and distinct from the Version type in Data.Version since Cabal-2.0. The difference extends to the Binary instance using a different (and more compact) encoding.

Since: Cabal-2.0.0.2
