# 0.2
* Support deriving `Invariant` and `Invariant2` instances with Template Haskell
* Added `invmapFunctor`, `invmapContravariant`, `invmap2Bifunctor`, and
`invmap2Profunctor` to make defining `Invmap` and `Invmap2` instances
somewhat easier
* Added `WrappedFunctor`, `WrappedContravariant`, `WrappedBifunctor`, and
`WrappedProfunctor` data types to allow use of `invmap` and `invmap2` for
data types that aren't `Invariant` or `Invariant2` instances.
* Added `Invariant` instances for lazy `ST`, `ArrowMonad`, `Handler`,
`Identity`, `First`, `Last`, `Alt`, `Proxy`, `ArgDescr`, `ArgOrder`, and
`OptDescr`
* Added `Invariant` and `Invariant2` instances for data types in the `array`,
`bifunctors`, `containers`, `profunctors`, `semigroups`, `stm`, `tagged`,
`transformers`, and `unordered-containers` libraries
# 0.1.2

* Bump `contravariant` upper version bounds
