CHANGELOG

4.2.0

• using the default context is the new recommended way to configure normalizers and encoders
• added a skip_null_values context option to not serialize properties with a null values
• AbstractNormalizer::handleCircularReference is now final and receives two optional extra arguments: the format and the context
• added support for XML comment encoding (encoding ['#comment' => ' foo '] results <!-- foo -->)
• added optional int[] $encoderIgnoredNodeTypes argument to XmlEncoder::__construct to configure node types to be ignored during encoding
• added AdvancedNameConverterInterface to access the class, the format and the context in a name converter
• the AbstractNormalizer::handleCircularReference() method will have two new $format and $context arguments in version 5.0, not defining them is deprecated
• deprecated creating a Serializer with normalizers which do not implement either NormalizerInterface or DenormalizerInterface
• deprecated creating a Serializer with normalizers which do not implement either NormalizerInterface or DenormalizerInterface
• deprecated creating a Serializer with encoders which do not implement either EncoderInterface or DecoderInterface
• added the optional $objectClassResolver argument in AbstractObjectNormalizer and ObjectNormalizer constructor
• added MetadataAwareNameConverter to configure the serialized name of properties through metadata
• YamlEncoder now handles the .yml extension too
• AbstractNormalizer::$circularReferenceLimit, AbstractNormalizer::$circularReferenceHandler, AbstractNormalizer::$callbacks, AbstractNormalizer::$ignoredAttributes, AbstractNormalizer::$camelizedAttributes, AbstractNormalizer::setCircularReferenceLimit(), AbstractNormalizer::setCircularReferenceHandler(), AbstractNormalizer::setCallbacks() and AbstractNormalizer::setIgnoredAttributes() are deprecated, use the default context instead.
• AbstractObjectNormalizer::$maxDepthHandler and AbstractObjectNormalizer::setMaxDepthHandler() are deprecated, use the default context instead.
• passing configuration options directly to the constructor of CsvEncoder, JsonDecode and XmlEncoder is deprecated since Symfony 4.2, use the default context instead.

4.1.0

• added CacheableSupportsMethodInterface for normalizers and denormalizers that use only the type and the format in their supports*() methods
• added MissingConstructorArgumentsException new exception for deserialization failure of objects that needs data insertion in constructor
• added an optional default_constructor_arguments option of context to specify a default data in case the object is not initializable by its constructor because of data missing
• added optional bool $escapeFormulas = false argument to CsvEncoder::__construct
• added AbstractObjectNormalizer::setMaxDepthHandler to set a handler to call when the configured maximum depth is reached
• added optional int[] $ignoredNodeTypes argument to XmlEncoder::__construct. XML decoding now ignores comment node types by default.
• added ConstraintViolationListNormalizer

4.0.0

• removed the SerializerAwareEncoder and SerializerAwareNormalizer classes, use the SerializerAwareTrait instead

• added an optional array $context = [] to Serializer::supportsNormalization, Serializer::supportsDenormalization, Serializer::supportsEncoding and Serializer::supportsDecoding

3.4.0

• added AbstractObjectNormalizer::DISABLE_TYPE_ENFORCEMENT context option to disable throwing an UnexpectedValueException on a type mismatch
• added support for serializing DateInterval objects
• added getter for extra attributes in ExtraAttributesException
• improved CsvEncoder to handle variable nested structures
• CSV headers can be passed to the CsvEncoder via the csv_headers serialization context variable
• added $context when checking for encoding, decoding and normalizing in Serializer

3.3.0

• added SerializerPass

3.1.0

• added support for serializing objects that implement JsonSerializable
• added the DenormalizerAwareTrait and NormalizerAwareTrait traits to support normalizer/denormalizer awareness
• added the DenormalizerAwareInterface and NormalizerAwareInterface interfaces to support normalizer/denormalizer awareness

• added a MaxDepth option to limit the depth of the object graph when serializing objects
• added support for serializing SplFileInfo objects
• added support for serializing objects that implement DateTimeInterface
• added AbstractObjectNormalizer as a base class for normalizers that deal with objects
• added support to relation deserialization

2.7.0

• added support for serialization and deserialization groups including annotations, XML and YAML mapping.
• added AbstractNormalizer to factorise code and ease normalizers development
• added circular references handling for PropertyNormalizer
• added support for a context key called object_to_populate in AbstractNormalizer to reuse existing objects in the deserialization process
• added NameConverterInterface and CamelCaseToSnakeCaseNameConverter
• [DEPRECATION] GetSetMethodNormalizer::setCamelizedAttributes() and PropertyNormalizer::setCamelizedAttributes() are replaced by CamelCaseToSnakeCaseNameConverter
• [DEPRECATION] the Exception interface has been renamed to ExceptionInterface
• added ObjectNormalizer leveraging the PropertyAccess component to normalize objects containing both properties and getters / setters / issers / hassers methods.
• added xml_type_cast_attributes context option for allowing users to opt-out of typecasting xml attributes.

2.6.0

• added a new serializer: PropertyNormalizer. Like GetSetMethodNormalizer, this normalizer will map an object's properties to an array.

2.5.0

• added support for is.* getters in GetSetMethodNormalizer

2.4.0

• added $context support for XMLEncoder.

2.2.0

• [BC BREAK] All Serializer, Normalizer and Encoder interfaces have been modified to include an optional $context array parameter.
• The XML Root name can now be configured with the xml_root_name parameter in the context option to the XmlEncoder.

• [BC BREAK] changed GetSetMethodNormalizer's key names from all lowercased to camelCased (e.g. mypropertyvalue to myPropertyValue)

• [BC BREAK] convert the item XML tag to an array
