--------------------
* Fix toggle report to output all settings.
[5.1.0] - 2023-08-02
--------------------
* Added support for Django 4.2
* Rename toggle_warnings to toggle_warning for consistency with setting_warning.
* Switch from ``edx-sphinx-theme`` to ``sphinx-book-theme`` since the former is
deprecated
[5.0.0] - 2022-04-22
--------------------
* BREAKING CHANGE: Removed LegacyWaffle* classes. Although this is a breaking change, all known uses have already been fixed.
* Handle the case where certain toggle names come in as ``None`` when generating summary reports.
* Add ADR for updating annotations for toggle life expectancy and use cases.
[4.3.0] - 2022-01-31
--------------------
Removed
~~~~~~~
* Removed Django22, 30, 31
Added
~~~~~~~
* Added Django40 support in CI
[4.2.0] - 2021-07-07
[4.1.0] - 2021-02-10
* Expose toggle state report via a Python API.
[4.0.0] - 2021-01-24
BREAKING CHANGE: Remove now unnecessary edx_toggles.toggles.__future__ module.
BREAKING CHANGE: Remove the following methods and properties: LegacyWaffleFlagNamespace.set_monitor_value, LegacyWaffleSwitch.switch_name, LegacyWaffleSwitch.namespaced_switch_name, LegacyWaffleFlag.flag_name, LegacyWaffleFlag.namespaced_flag_name, LegacyWaffleFlag.waffle_namespace.
BREAKING CHANGE: Remove LegacyWaffleFlagNamespace._set_monitor_value method
Monitoring:
Rename toggles.internal.legacy.Waffle* classes to toggles.internal.legacy.LegacyWaffle*.
[3.1.0] - 2021-01-18
* Dropped support for ``Python3.5``.
* Fix ``toggle_type`` column value from the toggle state report for the ``SettingToggle`` and ``SettingDictToggle`` classes: the column is now set to "django_settings".
[2.1.0] - 2021-01-12
WaffleFlag.set_monitor_value calls. The deprecated method is preserved for backward compatibility.[2.0.0] - 2020-11-05
* BREAKING CHANGE: The ``WaffleFlagNamespace`` and ``WaffleSwitchNamespace`` classes have been removed. You can either rename to ``LegacyWaffleFlagNamespace`` and ``LegacyWaffleSwitchNamespace``, which are deprecated, or you can move to the newer waffle classes that no longer use these Namespace classes (see below).
* BREAKING CHANGE: The ``WaffleFlag`` and ``WaffleSwitch`` classes exposed in ``toggles`` no longer use the Namespace classes and are now the classes which were previously only available in ``toggles.__future__``.
* If you were importing from ``edx_toggles.toggles.__future__`` before, then you simply need to import from ``edx_toggles.toggles``. Importing from ``__future__`` will continue to work but will trigger a deprecation warning.
* If you were importing from ``edx_toggles.toggles``, then you either need to:
* Migrate your legacy namespaced classes to the new-style classes (see the new behaviour below), or
* Import ``LegacyWaffleFlag`` instead of ``WaffleFlag`` and ``LegacyWaffleSwitch`` instead of ``WaffleSwitch``. Note that these classes will be removed soon, so it's preferable to migrate to the new classes already.
* The new Waffle classes introduce the following changes:
* They no longer use Namespace classes like ``WaffleSwitchNamespace`` or ``WaffleFlagNamespace``.
* The ``WaffleSwitchNamespace._namespaced_name`` and ``WaffleFlagNamespace._namespaced_name`` methods are replaced by the ``WaffleSwitch.name`` and ``WaffleFlag.name`` attributes.
* The ``WaffleSwitchNamespace.is_enabled`` method is replaced by the ``WaffleSwitch.is_enabled`` method.
* The ``WaffleSwitchNamespace.set_request_cache_with_short_name`` method has no replacement because an alternative solution should be found. You could (but really shouldn't) use the ``WaffleSwitch._cached_switches`` property.
* The ``WaffleSwitch.switch_name`` attribute is deprecated: switches should only ever be referred to using their fully namespaced names.
* The ``WaffleSwitch.switch_name`` attribute no longer exists. Switches should only ever be referred to using their fully namespaced names. If you need the non-namespaced name, it must be parsed from the namespaced name.
* The ``WaffleFlagNamespace.is_flag_active`` method is replaced by ``WaffleFlag.is_enabled``.
* The ``WaffleFlagNamespace._monitor_value`` method is replaced by ``WaffleFlag.set_monitor_value``.
* The ``WaffleFlagNamespace._cached_flags`` attribute is replaced by the ``WaffleFlag.cached_flags`` method.
* The ``WaffleFlag`` and ``WaffleSwitch`` ``module_name`` constructor argument is now mandatory.
* The ``WaffleFlag.flag_name`` attribute is deprecated.
* The ``WaffleFlag.flag_name`` attribute no longer exists. Flags should only ever be referred to using their fully namespaced names. If you need the non-namespaced name, it must be parsed from the namespaced name.
* The ``WaffleFlag.waffle_namespace`` attribute no longer exists, since there is no longer a separate namespace object.
[1.2.2] - 2020-12-22
More improvements to monitoring of legacy waffle class imports.
deprecated_incompatible_legacy_waffle_class custom attribute to any class (including subclasses), using the backward-incompatible imports that will be removed in 2.0.0.deprecated_compatible_legacy_waffle_class custom attribute to any class (including subclasses) using the legacy classes compatible with 2.0.0 imports, but which should be removed in 3.0.0 (or some future major version).deprecated_edx_toggles_waffle custom attribute. In two cases, it was replaced by the new *_legacy_waffle_class custom attributes. In one case, it was replaced with the already existing and more appropriate deprecated_waffle_legacy_method custom attribute.[1.2.1] - 2020-12-17
* Improve monitoring of legacy Waffle class imports. We should watch for "edx_toggles.toggles.internal.waffle.legacy.WaffleSwitch" custom attributes.
[1.2.0] - 2020-11-05
Start the deprecation process of the waffle namespace classes:
toggles.__future__ module for applications that need to be forward-compatible right away.[1.1.1] - 2020-10-27

override_waffle_switch test utility function from edx-platform[1.0.0] - 2020-10-13
* Fix missing ``module_name`` argument in ``SettingDictToggle`` constructor.
* Extract waffle classes from edx-platform and move them here following ADR `#2 <docs/decisions/0002-application-toggle-state.rst>`__, `#3 <docs/decisions/0003-django-setting-toggles.rst>`__, `#4 <docs/decisions/0004-toggle-api.rst>`__. This does not introduce backward-incompatible changes, *yet*.
* Fix pinned requirements and incorrect root url that overrode edx-platform's.
