     ``Singleton`` provider.
  5. Add ``ThreadLocalSingleton`` provider - ``Singleton`` provider that uses 
     thread-local storage.

     providers.
  7. Add ``set_args()`` and ``clear_args()`` methods for ``Callable``, 
     ``Factory`` and ``Singleton`` providers.

- **Containers**

  1. Module ``dependency_injector.containers`` was split into submodules 
     without any functional changes.

- **Utils**

  1. Module ``dependency_injector.utils`` is split into 
     ``dependency_injector.containers`` and ``dependency_injector.providers``.

- **Miscellaneous**

  1. Remove ``@inject`` decorator.
  2. Add makefile (``clean``, ``test``, ``build``, ``install``, ``uninstall`` 
     & ``publish`` commands).
  3. Update repository structure:

    1. Sources are moved under ``src/`` folder.
    2. Tests are moved under ``tests/unit/`` folder.

- Fixing minor bug in concept example.

0.7.6
-----

- Adding support of six from 1.7.0 to 1.9.0. 
- Factory / Singleton providers are free from restriction to operate with 
  classes only. This feature gives a change to use factory method and 
  functions with Factory / Singleton providers.
- All attributes of all entities that have to be protected was renamed using 
  ``_protected`` manner. 
- Providers extending was improved by implementing overriding logic in 
  ``Provider.__call__()`` and moving providing logic into 
  ``Provider._provide()``.
- ``NewInstance`` provider was renamed to ``Factory`` provider. 
  ``NewInstance`` still can be used, but it considered to be deprecated and 
  will be removed in further releases.
- ``@inject`` decorator was refactored to keep all injections in 
  ``_injections`` attribute of decorated callback. It will give a possibility to
  track all the injections of particular callbacks and gives some performance 
  boost due minimizing number of calls for doing injections.
- A lot of documentation updates were made.
- A lot of examples were added.
- Some minor refactorings were done.

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

- While *Objects* was in alpha state, changes were not tracked.
