+CHANGELOG
+=========
+
+4.4.0
+-----
+
+ * added a way to exclude patterns of resources from being imported by the `import()` method
+
+4.3.0
+-----
+
+ * deprecated using environment variables with `cannotBeEmpty()` if the value is validated with `validate()`
+ * made `Resource\*` classes final and not implement `Serializable` anymore
+ * deprecated the `root()` method in `TreeBuilder`, pass the root node information to the constructor instead
+
+4.2.0
+-----
+
+ * deprecated constructing a `TreeBuilder` without passing root node information
+ * renamed `FileLoaderLoadException` to `LoaderLoadException`
+
+4.1.0
+-----
+
+ * added `setPathSeparator` method to `NodeBuilder` class
+ * added third `$pathSeparator` constructor argument to `BaseNode`
+ * the `Processor` class has been made final
+
+4.0.0
+-----
+
+ * removed `ConfigCachePass`
+
+3.4.0
+-----
+
+ * added `setDeprecated()` method to indicate a deprecated node
+ * added `XmlUtils::parse()` method to parse an XML string
+ * deprecated `ConfigCachePass`
+
+3.3.0
+-----
+
+ * added `ReflectionClassResource` class
+ * added second `$exists` constructor argument to `ClassExistenceResource`
+ * made `ClassExistenceResource` work with interfaces and traits
+ * added `ConfigCachePass` (originally in FrameworkBundle)
+ * added `castToArray()` helper to turn any config value into an array
+
+3.0.0
+-----
+
+ * removed `ReferenceDumper` class
+ * removed the `ResourceInterface::isFresh()` method
+ * removed `BCResourceInterfaceChecker` class
+ * removed `ResourceInterface::getResource()` method
+
+2.8.0
+-----
+
+The edge case of defining just one value for nodes of type Enum is now allowed:
+
+```php
+$rootNode
+    ->children()
+        ->enumNode('variable')
+            ->values(['value'])
+        ->end()
+    ->end()
+;
+```
+
+Before: `InvalidArgumentException` (variable must contain at least two
+distinct elements).
+After: the code will work as expected and it will restrict the values of the
+`variable` option to just `value`.
+
+ * deprecated the `ResourceInterface::isFresh()` method. If you implement custom resource types and they
+   can be validated that way, make them implement the new `SelfCheckingResourceInterface`.
+ * deprecated the getResource() method in ResourceInterface. You can still call this method
+   on concrete classes implementing the interface, but it does not make sense at the interface
+   level as you need to know about the particular type of resource at hand to understand the
+   semantics of the returned value.
+
+2.7.0
+-----
+
+ * added `ConfigCacheInterface`, `ConfigCacheFactoryInterface` and a basic `ConfigCacheFactory`
+   implementation to delegate creation of ConfigCache instances
+
+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
