    v36 v37  
    8181A field ''Way'' of type `[String]`. It tracks the way in which the package was compiled. It is a subset of `{v,d,p}`. "v" means vanilla, "d" means dynamic linking and "p" means profiling. Other ways may be added later. 
    8282 
    83 A timestamp of the time when the package was installed (or built?). It is used by GHC and Cabal to put a preference on the latest package of a certain version. 
    84  
    85 A currently empty but extensible set of fields starting with "x-cabal-...". ghc-pkg ignores them when parsing. During the resolution phase cabal-install might use them to decide compatibility between packages. 
    86  
    87 A field abi-hash that contains the ABI hash because it is now longer stored implicitly as part of the `InstalledPackageId`.
