- Showing an undefined error for an object that raises
``AttributeError`` on access doesn't cause a recursion error.
:issue:`1177`
+- Revert changes to :class:`~loaders.PackageLoader` from 2.10 which
+ removed the dependency on setuptools and pkg_resources, and added
+ limited support for namespace packages. The changes caused issues
+ when using Pytest. Due to the difficulty in supporting Python 2 and
+ :pep:`451` simultaneously, the changes are reverted until 3.0.
+ :pr:`1182`
Version 2.11.1
