# Changelog for recursion-schemes-ix
## 0.0.1.0
Initial release
Multiple last-minute changes:
* Switched from `singletons` to `singlethongs`
- `singletons` has unnecessary dependencies, and is unable to compile
with the current `ghcjs` version.
* Removed QuantifiedConstraints extension usage throughout
- Allowed the removal of UndecidableInstances in most files
* Added the `ITraversable` class and monadic recursion-schemes
- TODO: determine if `IFunctor` should just be removed,
ie. determine if there are any `IFunctor`s that are not `ITraversable`
