- Fix bug in :class:`~chide.Collection` occurring when sample attributes were not hashable.
2.1.1
-------------------
- Exclude tests from distribution.
2.1.0
-------------------
- add :meth:`~chide.Collection.attributes`.
2.0.1
-------------------
- Fix nasty bug when using with :mod:`sqlalchemy` where related objects could get added to the session even though they were never requested, as a result of a backref on a third model.
2.0.0
-------------------
- Backwards incompatible change to split the concern for sample object identity out into :class:`chide.Set` and :class:`chide.sqlalchemy.Set` to avoid module-level :class:`~chide.Collection` instances resulting in cross-test pollution.
