|  Download CHANGELOG3.0.0 * removed ReferenceDumperclass
 * removed theResourceInterface::isFresh()method
 * removedBCResourceInterfaceCheckerclass
 * removedResourceInterface::getResource()method 2.8.0The edge case of defining just one value for nodes of type Enum is now allowed: $rootNode
    ->children()
        ->enumNode('variable')
            ->values(array('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 thevariableoption to justvalue.  * deprecated the ResourceInterface::isFresh()method. If you implement custom resource types and they
   can be validated that way, make them implement the newSelfCheckingResourceInterface.
 * 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,ConfigCacheFactoryInterfaceand a basicConfigCacheFactoryimplementation to delegate creation of ConfigCache instances 2.2.0 * added ArrayNodeDefinition::canBeEnabled()andArrayNodeDefinition::canBeDisabled()to ease configuration when some sections are respectively disabled / enabled
   by default.
 * added anormalizeKeys()method for array nodes (to avoid key normalization)
 * added numerical type handling for config definitions
 * added convenience methods for optional configuration sections toArrayNodeDefinition* added a utils class for XML manipulations 2.1.0 * added a way to add documentation on configuration
 * implemented Serializableon resources
 *LoaderResolverInterfaceis now used instead ofLoaderResolverfor type
