-------------------

New Features
++++++++++++

- None

Bug Fixes
+++++++++

- Fix regression in ``get`` where ``list`` and ``dict`` objects had attributes returned when a key was missing but the key corresponded to an attribute name. For example, ``pydash.get({}, 'update')`` would return ``{}.update()`` instead of ``None``. Previous behavior was that only item-access was allowed for ``list`` and ``dict`` which has been restored.
- Fix regression in ``invoke``/``invoke_map`` where non-attributes could be invoked. For example, ``pydash.invoke({'items': lambda: 1}, 'items')`` would return ``1`` instead of ``dict_items([('a', 'items')])``. Previous behavior was that only attribute methods could be invoked which has now been restored.

New Features

- None

Bug Fixes
+++++++++

- Fix regression in ``intersection``, ``intersection_by``, and ``intersection_with`` introduced in ``v4.0.0`` where the a single argument supplied to intersection should return the same argument value instead of an empty list.

- None

-------------------

New Features
++++++++++++

- Make ``property_`` work with deep path strings.

Bug Fixes
+++++++++

- Revert removal of ``deep_pluck`` and rename to ``pluck``. Previously, ``deep_pluck`` was removed and ``map_`` was recommended as a replacement. However, ``deep_pluck`` (now defined as ``pluck``) functionality is not supported by ``map_`` so the removal ``pluck`` was reverted.

Backwards-Incompatibilities
+++++++++++++++++++++++++++

- Remove ``property_deep`` (use ``property_``).

Bug Fixes
