data-fix v0.3.0 Release Notes

    • 📇 Rename cata, ana and hylo into foldFix, unfoldFix and `refold. Old names are now deprecated, and will be eventually removed. Similarly, rename monadic variants.
    • ➕ Add hoistFix and hoistFix' function.
    • ➕ Add Hashable and NFData instance. Latter is available only with deepseq >=1.4.3.0, which provides NFData1 type-class
    • 🔄 Change Eq, Ord, Show and Read instances to use Eq1, Ord1, Show1 and Read1 instances of a base functor.
    • ➕ Add least and greatest fixed point types, Mu and Nu.
    • ⬇️ Drop requirement for Applicative m in monadic combinators, Monad m is enough.
    • ✂ Remove ~> alias for refold (hylo).
    • 👍 Extend the GHC support window. There is nothing magical in this package.
    • Mark Data.Fix as Trustworthy (Safe Haskell)
    • 👉 Make refold (and refoldM) more efficient. This results in different effect ordering for refoldM.
