 -------------------
-- Add ``loader`` argument to the configuration provider ``Configuration.from_yaml(..., loader=...)`` to override the
-  default YAML loader.
+- Add ``loader`` argument to the configuration provider ``Configuration.from_yaml(..., loader=...)``
+  to override the default YAML loader.
 - Make security improvement: change default YAML loader to the custom ``yaml.SafeLoader`` with a support
   of environment variables interpolation.
 - Update configuration provider ``.from_*()`` methods to raise an exception in strict mode if
   configuration file does not exist or configuration data is undefined.
+- Add ``required`` argument to the configuration provider ``.from_*()`` methods to specify
+  mandatory configuration sources.
 - Fix a bug with asynchronous injections: async providers do not work with async dependencies.
   See issue: `#368 <https://github.com/ets-labs/python-dependency-injector/issues/368>`_.
