Off topic: They use the Semantic Versioning Specification ( http://semver.org/ http://semver.org/ ). Interesting, I had never heard of this. Are there many projects using it? It sounds very similar to the Package Versioning Policy ( http://www.haskell.org/haskellwiki/Package_versioning_policy http://www.haskell.org/haskellwiki/Package_versioning_policy ) which many Haskell packages use, only not specific to one language.
