## 1.2.x

  - allows devs who want to compile the code to do so
  - better excludes files that are not needed for distribution
- 1.2.2 [Nik Butenko](http://butenko.me/) gave us some nice updates ()
  - [Issue #10](https://github.com/HurricaneJames/react-immutable-proptypes/pull/10) now have better errors when typechecker(s) provided in `propTypes` definition is invalid
  - [Issue #9](https://github.com/HurricaneJames/react-immutable-proptypes/pull/9) removed use of `new` Immutable objects in tests
- 1.2.1 updated documentation to reflect that Immutable object instantiation does not require `new`
