2.6.1 (2017.01.11)
------------------

  in the the documentation.

* Fix `SoftDeletableModel.delete()` to use the correct database connection.
  Merge of GH-239.

* Added boolean keyword argument `soft` to `SoftDeletableModel.delete()` that
  revert to default behavior when set to `False`. Merge of GH-240.

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

* Drop support for Python 3.2.

* Add support for Django 1.10 pre-alpha.

* Track foreign keys on parent models properly when a tracker
  is defined on a child model. Fixes GH-214.


2.4 (2015.12.03)
----------------

* Remove `PassThroughManager`. Use Django's built-in `QuerySet.as_manager()`
  and/or `Manager.from_queryset()` utilities instead.

* Add support for Django 1.9.


2.3.1 (2015-07-20)
------------------

* Remove all translation-related automation in `setup.py`. Fixes GH-178 and
  GH-179. Thanks Joe Weiss, Matt Molyneaux, and others for the reports.


2.3 (2015.07.17)
----------------

* Keep track of deferred fields on model instance instead of on
  FieldInstanceTracker instance. Fixes accessing deferred fields for multiple
  instances of a model from the same queryset. Thanks Bram Boogaard. Merge of
  GH-151.

* Fix Django 1.7 migrations compatibility for SplitField. Thanks ad-m. Merge of
  GH-157; fixes GH-156.

* Add German translations.

* Django 1.8 compatibility.


2.2 (2014.07.31)
----------------

* Revert GH-130, restoring ability to access ``FieldTracker`` changes in
  overridden ``save`` methods or ``post_save`` handlers. This reopens GH-83
  (inability to pickle models with ``FieldTracker``) until a solution can be
  found that doesn't break behavior otherwise. Thanks Brian May for the
  report. Fixes GH-143.


2.1.1 (2014.07.28)
------------------

* ASCII-fold all non-ASCII characters in changelog; again. Argh. Apologies to
  those whose names are mangled by this change. It seems that distutils makes
  it impossible to handle non-ASCII content reliably under Python 3 in a
  setup.py long_description, when the system encoding may be ASCII. Thanks
  Brian May for the report. Fixes GH-141.


2.1.0 (2014.07.25)
------------------

* Add support for Django's built-in migrations to ``MonitorField`` and
  ``StatusField``.

* ``PassThroughManager`` now has support for seeing exposed methods via
  ``dir``, allowing `IPython`_ tab completion to be useful. Merge of GH-104,
  fixes GH-55.

* Add pickle support for models using ``FieldTracker``.  Thanks Ondrej Slintak
  for the report.  Thanks Matthew Schinckel for the fix.  Merge of GH-130,
  fixes GH-83.

.. _IPython: http://ipython.org/


2.0.3 (2014.03.19)
-------------------

* Fix ``get_query_set`` vs ``get_queryset`` in ``PassThroughManager`` for
  Django <1.6. Fixes issues with related managers not filtering by relation
  properly. Thanks whop, Bojan Mihelac, Daniel Shapiro, and Matthew Schinckel
  for the report; Matthew for the fix. Merge of GH-121.

* Fix ``FieldTracker`` with deferred model attributes. Thanks Michael van
  Tellingen. Merge of GH-115.

* Fix ``InheritanceManager`` with self-referential FK; avoid infinite
  recursion. Thanks rsenkbeil. Merge of GH-114.

2.0.2 (2014.02.19)
-------------------

* ASCII-fold all non-ASCII characters in changelog. Apologies to those whose
  names are mangled by this change. It seems that distutils makes it impossible
  to handle non-ASCII content reliably under Python 3 in a setup.py
  long_description, when the system encoding may be ASCII. Thanks Simone Dalla
  for the report. Fixes GH-113.


2.0.1 (2014.02.11)
-------------------

* Fix dependency to be on "Django" rather than "django", which plays better
  with static PyPI mirrors. Thanks Travis Swicegood.

* Fix issue with attempt to access ``__slots__`` when copying
  ``PassThroughManager``. Thanks Patryk Zawadzki. Merge of GH-105.

* Improve ``InheritanceManager`` so any attributes added by using extra(select)
  will be propagated onto children. Thanks Curtis Maloney. Merge of GH-101,
  fixes GH-34.

* Added ``InheritanceManagerMixin``, ``InheritanceQuerySetMixin``,
  ``PassThroughManagerMixin``, and ``QueryManagerMixin`` to allow composing
  their functionality with other custom manager/queryset subclasses (e.g. those
  in GeoDjango). Thanks Douglas Meehan!


2.0 (2014.01.06)
----------------

* BACKWARDS-INCOMPATIBLE: Indexing into a ``Choices`` instance now translates
  database representations to human-readable choice names, rather than simply
  indexing into an array of choice tuples. (Indexing into ``Choices`` was
  previously not documented.) If you have code that is relying on indexing or
  slicing ``Choices``, the simplest workaround is to change e.g. ``STATUS[1:]``
  to ``list(STATUS)[1:]``.

* Fixed bug with checking for field name conflicts for added query managers on
  `StatusModel`.

* Can pass `choices_name` to `StatusField` to use a different name for
  choices class attribute. ``STATUS`` is used by default.

* Can pass model subclasses, rather than strings, into
  `select_subclasses()`. Thanks Keryn Knight. Merge of GH-79.

* Deepcopying a `Choices` instance no longer fails with infinite recursion in
  `getattr`. Thanks Leden. Merge of GH-75.

* `get_subclass()` method is now available on both managers and
  querysets. Thanks Travis Swicegood. Merge of GH-82.

* Fix bug in `InheritanceManager` with grandchild classes on Django 1.6+;
  `select_subclasses('child', 'child__grandchild')` would only ever get to the
  child class. Thanks Keryn Knight for report and proposed fix.

* MonitorField now accepts a 'when' parameter. It will update only when the field
  changes to one of the values specified.


1.5.0 (2013.08.29)
------------------

* `Choices` now accepts option-groupings. Fixes GH-14.

* `Choices` can now be added to other `Choices` or to any iterable, and can be
  compared for equality with itself. Thanks Tony Aldridge. (Merge of GH-76.)

* `Choices` now `__contains__` its Python identifier values. Thanks Keryn
  Knight. (Merge of GH-69).

* Fixed a bug causing ``KeyError`` when saving with the parameter
  ``update_fields`` in which there are untracked fields. Thanks Mikhail
  Silonov. (Merge of GH-70, fixes GH-71).

* Fixed ``FieldTracker`` usage on inherited models.  Fixes GH-57.

* Added mutable field support to ``FieldTracker`` (Merge of GH-73, fixes GH-74)


1.4.0 (2013.06.03)
------------------

- Introduced ``FieldTracker`` as replacement for ``ModelTracker``, which is now
  deprecated.

- ``PassThroughManager.for_queryset_class()`` no longer ignores superclass
  ``get_query_set``. Thanks Andy Freeland.

- Fixed ``InheritanceManager`` bug with grandchildren in Django 1.6. Thanks
  CrazyCasta.

- Fixed lack of ``get_FOO_display`` method for ``StatusField``. Fixes GH-41.


1.3.1 (2013.04.11)
------------------

- Added explicit default to ``BooleanField`` in tests, for Django trunk
  compatibility.

- Fixed intermittent ``StatusField`` bug.  Fixes GH-29.

- Added Python 3 support.

- Dropped support for Django 1.2 and 1.3.  Django 1.4.2+ required.


1.3.0 (2013.03.27)
------------------

- Allow specifying default value for a ``StatusField``. Thanks Felipe
  Prenholato.

- Fix calling ``create()`` on a ``RelatedManager`` that subclasses a dynamic
  ``PassThroughManager``. Thanks SeiryuZ for the report. Fixes GH-24.

- Add workaround for https://code.djangoproject.com/ticket/16855 in
  InheritanceQuerySet to avoid overriding prior calls to
  ``select_related()``. Thanks ivirabyan.

- Added support for arbitrary levels of model inheritance in
  InheritanceManager. Thanks ivirabyan. (This feature only works in Django
  1.6+ due to https://code.djangoproject.com/ticket/16572).

- Added ``ModelTracker`` for tracking field changes between model saves. Thanks
  Trey Hunner.


1.2.0 (2013.01.27)
------------------

- Moved primary development from `Bitbucket`_ to `GitHub`_. Bitbucket mirror
  will continue to receive updates; Bitbucket issue tracker will be closed once
  all issues tracked in it are resolved.

.. _BitBucket: https://bitbucket.org/carljm/django-model-utils/overview
.. _GitHub: https://github.com/carljm/django-model-utils/

- Removed deprecated ``ChoiceEnum``, ``InheritanceCastModel``,
  ``InheritanceCastManager``, and ``manager_from``.

- Fixed pickling of ``PassThroughManager``. Thanks Rinat Shigapov.

- Set ``use_for_related_fields = True`` on ``QueryManager``.

- Added ``__len__`` method to ``Choices``. Thanks Ryan Kaskel and James Oakley.

- Fixed ``InheritanceQuerySet`` on Django 1.5. Thanks Javier Garcia Sogo.

1.1.0 (2012.04.13)
------------------

- Updated AutoCreatedField, AutoLastModifiedField, MonitorField, and
  TimeFramedModel to use ``django.utils.timezone.now`` on Django 1.4.
  Thanks Donald Stufft.

- Fixed annotation of InheritanceQuerysets. Thanks Jeff Elmore and Facundo
  Gaich.

- Dropped support for Python 2.5 and Django 1.1. Both are no longer supported
  even for security fixes, and should not be used.

- Added ``PassThroughManager.for_queryset_class()``, which fixes use of
  ``PassThroughManager`` with related fields. Thanks Ryan Kaskel for report and
  fix.

- Added ``InheritanceManager.get_subclass()``. Thanks smacker.

1.0.0 (2011.06.16)
------------------

- Fixed using SplitField on an abstract base model.

- Fixed issue #8, adding ``use_for_related_fields = True`` to
  ``InheritanceManager``.

- Added ``PassThroughManager``. Thanks Paul McLanahan.

- Added pending-deprecation warnings for ``InheritanceCastModel``,
  ``manager_from``, and Django 1.1 support. Removed documentation for the
  deprecated utilities. Bumped ``ChoiceEnum`` from pending-deprecation to
  deprecation.

- Fixed issue #6, bug with InheritanceManager and descriptor fields (e.g.
  FileField).  Thanks zyegfryed for the fix and sayane for tests.

0.6.0 (2011.02.18)
------------------

- updated SplitField to define get_prep_value rather than get_db_prep_value.
  This avoids deprecation warnings on Django trunk/1.3, but makes SplitField
  incompatible with Django versions prior to 1.2.

- added InheritanceManager, a better approach to selecting subclass instances
  for Django 1.2+. Thanks Jeff Elmore.

- added InheritanceCastManager and InheritanceCastQuerySet, to allow bulk
  casting of a queryset to child types.  Thanks Gregor Muellegger.

0.5.0 (2010.09.24)
------------------

- added manager_from (thanks George Sakkis)
- added StatusField, MonitorField, TimeFramedModel, and StatusModel
  (thanks Jannis Leidel)
- deprecated ChoiceEnum and replaced with Choices

0.4.0 (2010.03.16)
------------------

- added SplitField
- added ChoiceEnum
- added South support for custom model fields

0.3.0
-----

* Added ``QueryManager``
