+# Change Log
+All notable changes to the `monad-memo` project will be documented in this file
+
+## [0.5.2] - 2020-09-20
+### Added
+- CI on Github actions with test coverage and Hackage upload
+### Fixed
+- `monad-memo.cabal` structure: redundancy and to enable test coverage calculation
+- `CHANGELOG.md` structure
+
+## [0.5.1] - 2018-08-31
+### Added
+- Support multiple mutable caches in transformers stack
+  This allows Array/Vector-based caches to be used for mutually recursive function memoization
+
+## [0.5.0] - 2018-08-06
+### Fixed
+- Refresh project to be compilable with latest GHC and libraries
+- Remove dependency on `mtl` package (`transformers` is sufficient)
+- Use `Except` instead of deprecated `Error`
+- Remove support for `ListT` transformer since it is now deprecated
+- Use standard `StateT` & `ReaderT` for `MonadCache` implementations
+
+## [0.4.1] - 2013-03-06
+### Fixed
+- Documentation
+- `Example` is renamed to `example` and is excluded from package's module hierarchy
+
+## [0.4.0] - 2013-02-26
+### Added
+- `ArrayCache`: mutable array-based `MonadCache` for top performance
+- `VectorCache` (and flavours) `vector`-based `MonadCache` for even better performance
+- Simple benchmark included
+### Fixed
+- Bug fixes in transformer implementations (`Reader`, `State`, `RWS`)
+
+## [0.3.0] - 2011-04-03
+### Added
+- Added generalized `MemoStateT` transformer (to host any `Data.MapLike` cache-container)
+- `MemoT` is now `MemoStateT` instantiated with `Data.Map`
+
+## [0.2.0] - 2011-03-27
+### Added
+- A set of `forX` functions (`for2`, `for3` and `for4`) to adapt curried function into uncurried `MemoCache`
