Settei

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

Released on July 24, 2017.

- Added ``recurse`` option to :class:`~settei.base.config_object_property`.
If it's :const:`True` nested tables are also evaluated. :const:`False` by
default for backward compatibility.

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

Released on May 14, 2017.

- :class:`~settei.base.config_object_property` was added. It's a kind of
dependency injection, but very limited version.

- :exc:`~settei.base.ConfigError`, :exc:`~settei.base.ConfigKeyError`,
:exc:`~settei.base.ConfigTypeError`, and :exc:`~settei.base.ConfigValueError`.

Prior to 0.4.0, :class:`~settei.base.Configuration` had raised Python's
built-in :exc:`KeyError` on missing keys, but since 0.4.0 it became to raise
:exc:`~settei.base.ConfigKeyError`, a subtype of :exc:`KeyError`, instead.

In the same manner, while prior to 0.4.0, it had raised Python's
built-in :exc:`TypeError` when a configured value is not of a type it expects,
but since 0.4.0 it became to raise :exc:`~settei.base.ConfigTypeError`
instead. :exc:`~settei.base.ConfigTypeError` is also a subtype of
:class:`TypeError`.

Released on November 18, 2016. Note that the version 0.2.1 has never been
released due to our mistake on versioning.

- :class:`~settei.presets.celery.WorkerConfiguration` became to have
:attr:`~settei.presets.celery.WorkerConfiguration.worker_schedule`
config property to configure Celery beat --- Celery's periodic tasks.

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

Released on July 13, 2016.

- :mod:`settei` became a package (had been a module), which contains
:mod:`settei.base` module.
- :class:`settei.Configuration`, :class:`settei.ConfigWarning`, and
:class:`settei.config_property` were moved to :mod:`settei.base` module.
Although aliases for these previous import paths will be there for a while,
we recommend to import them from :mod:`settei.base` mdoule since they are
deprecated.

- Presets were introduced: :mod:`settei.presets`.

- :mod:`settei.presets.celery` is for configuring Celery_ apps.
- :mod:`settei.presets.flask` is for configuring Flask_ web apps.
- :mod:`settei.presets.logging` is for configuring Python standard
:mod:`logging` system.

- :mod:`settei.version` module was added.
- typeannotations_ was replaced by tsukkomi_.
- Settei now requires pytoml_ 0.1.10 or higher. (It had required 0.1.7 or
higher.)
