+## 0.3.0
+
+- 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`.
