Added - `ReprHelperMixin` to simplify [manual generation](http://pythonhosted.org/Represent/usage/helper/)
Fixed - `PrettyReprHelper.positional_from_attr()` didn't check for cycle, causing recursion limit to be reached for self-referential objects.
1.2.1
Fixed - `__init__.py` was missing from represent.compat, so wasn't packaged for PyPI.
1.2.0
Changed - `RepresentationMixin` has been renamed to `ReprMixin`. - `RepresentationHelper` has been renamed to `ReprHelper`. - `PrettyRepresentationHelper` has been renamed to `PrettyReprHelper`.
Added - `ReprMixinBase` is available if user does not want to inherit `__getstate__` and `__setstate__` from `ReprMixin`. - Documentation about Pickle support for `ReprMixin` (2)
Deprecated
These aliases will raise deprecation warnings: - `RepresentationMixin` - `RepresentationHelper` - `PrettyRepresentationHelper`
1.1.0
