7 * added `setDeprecated()` method to indicate a deprecated node
8 * added `XmlUtils::parse()` method to parse an XML string
9 * deprecated `ConfigCachePass`
14 * added `ReflectionClassResource` class
15 * added second `$exists` constructor argument to `ClassExistenceResource`
16 * made `ClassExistenceResource` work with interfaces and traits
17 * added `ConfigCachePass` (originally in FrameworkBundle)
18 * added `castToArray()` helper to turn any config value into an array
23 * removed `ReferenceDumper` class
24 * removed the `ResourceInterface::isFresh()` method
25 * removed `BCResourceInterfaceChecker` class
26 * removed `ResourceInterface::getResource()` method
31 The edge case of defining just one value for nodes of type Enum is now allowed:
36 ->enumNode('variable')
37 ->values(array('value'))
43 Before: `InvalidArgumentException` (variable must contain at least two
45 After: the code will work as expected and it will restrict the values of the
46 `variable` option to just `value`.
48 * deprecated the `ResourceInterface::isFresh()` method. If you implement custom resource types and they
49 can be validated that way, make them implement the new `SelfCheckingResourceInterface`.
50 * deprecated the getResource() method in ResourceInterface. You can still call this method
51 on concrete classes implementing the interface, but it does not make sense at the interface
52 level as you need to know about the particular type of resource at hand to understand the
53 semantics of the returned value.
58 * added `ConfigCacheInterface`, `ConfigCacheFactoryInterface` and a basic `ConfigCacheFactory`
59 implementation to delegate creation of ConfigCache instances
64 * added `ArrayNodeDefinition::canBeEnabled()` and `ArrayNodeDefinition::canBeDisabled()`
65 to ease configuration when some sections are respectively disabled / enabled
67 * added a `normalizeKeys()` method for array nodes (to avoid key normalization)
68 * added numerical type handling for config definitions
69 * added convenience methods for optional configuration sections to `ArrayNodeDefinition`
70 * added a utils class for XML manipulations
75 * added a way to add documentation on configuration
76 * implemented `Serializable` on resources
77 * `LoaderResolverInterface` is now used instead of `LoaderResolver` for type
