-CHANGELOG
-=========
-
-2.2.0
------
-
- * added ArrayNodeDefinition::canBeEnabled() and ArrayNodeDefinition::canBeDisabled()
-   to ease configuration when some sections are respectively disabled / enabled
-   by default.
- * added a `normalizeKeys()` method for array nodes (to avoid key normalization)
- * added numerical type handling for config definitions
- * added convenience methods for optional configuration sections to ArrayNodeDefinition
- * added a utils class for XML manipulations
-
-2.1.0
------
-
- * added a way to add documentation on configuration
- * implemented `Serializable` on resources
- * LoaderResolverInterface is now used instead of LoaderResolver for type
-   hinting

-Config Component
-================
-
-Config provides the infrastructure for loading configurations from different
-data sources and optionally monitoring these data sources for changes. There
-are additional tools for validating, normalizing and handling of defaults that
-can optionally be used to convert from different formats to arrays.
-
-Resources
----------
-
-You can run the unit tests with the following command:
-
-    $ cd path/to/Symfony/Component/Config/
-    $ composer install
-    $ phpunit
