1.0.0 (January 7th, 2019)

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

Backwards incompatible changes:

* Dropped support for Python 2.7. Everett no longer supports Python 2. (#73)

* Dropped support for Python 3.3 and added support for Python 3.7. Thank you,
  pjz! (#68)

* Moved ``ConfigIniEnv`` to a different module. Now you need to import it
  like this::

      from everett.ext.inifile import ConfigIniEnv

  (#79)

Features:

* Everett now logs configuration discovery in the ``everett`` logger at the
  ``logging.DEBUG`` level. This is helpful for trouble-shooting some kinds of
  issues. (#74)

Fixes:

* Everett no longer requires ``configobj``--it's now optional. If you use
  ``ConfigIniEnv``, you can install it with::

      $ pip install everett[ini]

  (#79)

* Fixed list parsing and file discovery in ConfigIniEnv so they match the
  docs and are more consistent with other envs. Thank you, apollo13! (#71)

* Added a ``.basic_config()`` for fast opinionated setup that uses the
  process environment and a ``.env`` file in the current working directory.

* Switching to semver.

0.9 (April 7th, 2017)

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

Changed:

* Rewrite Sphinx extension. The extension is now in the ``everett.sphinxext``
  module and the directive is now ``.. autocomponent::``. It generates better
  documentation and it now indexes Everett components and options.

  This is backwards-incompatible. You will need to update your Sphinx
  configuration and documentation.

* Changed the ``HISTORY.rst`` structure.

* Changed the repr for ``everett.NO_VALUE`` to ``"NO_VALUE"``.

* ``InvalidValueError`` and ``ConfigurationMissingError`` now have
  ``namespace``, ``key``, and ``parser`` attributes allowing you to build your
  own messages.

Fixed:

* Fix an example in the docs where the final key was backwards. Thank you, pjz!

Documentation fixes and updates.

0.8 (January 24th, 2016)

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

Feature: Add ``:namespace:`` and ``:case:`` arguments to autoconfig
directive. These make it easier to cater your documentation to your
project's needs.

Feature: Add support for Python 3.6.

Minor documentation fixes and updates.

0.7 (January 5th, 2016)

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

Feature: You can now include documentation hints and urls for
``ConfigManager`` objects and config options. This will make it easier
for your users to debug configuration errors they're having with your
software.

Bug: Fix ``ListOf`` so it returns empty lists rather than a list with
a single empty string.

Documentation fixes and updates.

0.6 (November 28th, 2016)

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

Feature: Change ``:show-docstring:`` to take an optional value which is
the attribute to pull docstring content from. This means you don't have
to mix programming documentation with user documentation--they can be in
different attributes.

Feature: Add ``RequiredConfigMixin.get_runtime_config()`` which returns
the runtime configuration for a component or tree of components. This
lets you print runtime configuration at startup, generate INI files,
etc.

Feature: Add ``ConfigObjEnv`` which lets you use an object for
configuration. This works with argparse's Namespace amongst other
things.

Feature: Improve configuration-related exceptions. With Python 3,
configuration errors all derive from ``ConfigurationError`` and have
helpful error messages that should make it clear what's wrong with the
configuration value. With Python 2, you can get other kinds of
Exceptions thrown depending on the parser used, but configuration error
messages should still be helpful.

Documentation fixes and updates.

0.5 (November 8th, 2016)

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

Feature: Add ``:show-docstring:`` flag to ``autoconfig`` directive.

Feature: Add ``:hide-classname:`` flag to ``autoconfig`` directive.

Feature: Rewrite ``ConfigIniEnv`` to use configobj which allows for nested
sections in INI files. This also allows you to specify multiple INI files
and have later ones override earlier ones.

Bug: Fix ``autoconfig`` Sphinx directive and add tests--it was all kinds of
broken.

0.4 (October 27th, 2016)

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

Feature: Add ``raw_value`` argument to config calls. This makes it easier to
write code that prints configuration.

Bug: Fix ``listify(None)`` to return ``[]``.

Documentation fixes and updates.

Tag v0.3.1

0.3.1 (October 12th, 2016)
--------------------------

Bug: Fix ``alternate_keys`` with components. Previously it worked for everything
but components. Now it works with components, too.

Tag v0.3

0.3 (October 6th, 2016)
-----------------------

Feature: Add ``ConfigManager.from_dict()`` shorthand for building configuration
instances.

Feature: Add ``.get_namespace()`` to ``ConfigManager`` and friends for getting
the complete namespace for a given config instance as a list of strings.

Feature: Make ``ConfigDictEnv`` case-insensitive to keys and namespaces.

Feature: Add ``alternate_keys`` to config call. This lets you specify a list
of keys in order to try if the primary key doesn't find a value. This is
helpful for deprecating keys that you used to use in a backwards-compatible
way.

Feature: Add ``root:`` prefix to keys allowing you to look outside of the
current namespace and at the configuration root for configuration values.

0.2 (August 16th, 2016)

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

Feature: Add ``ConfigEnvFileEnv`` for supporting ``.env`` files. Thank you,
Paul!

Feature: Change ``ConfigIniEnv`` to take a single path or list of paths. Thank
you, Paul!

Feature: Add "on" and "off" as valid boolean values. This makes it easier to use
config for feature flippers. Thank you, Paul!

Feature: Make ``NO_VALUE`` falsy.

Bug: Fix ``__call__`` returning None--it should return ``NO_VALUE``.

Lots of docs updates: finished the section about making your own parsers, added
a section on using dj-database-url, added a section on django-cache-url and
expanded on existing examples.
