1.8.0 [20-Apr-2011]
Another minor release. Main improvements are:
- Proper configurability for key serializers, deserializers
- Ability to control details of low-level character escaping
- Pluggable format auto-detection (for JSON and Smile in core packages)
- Fully configurable type-defaulting (abstract-to-concrete) for deserialization
- Pass-through FormatSchema abstraction to help support schema-based formats
New features:
* [JACKSON-43]: Add "ObjectMapper.readValues()", "ObjectReader.readValues()" for
more convenient binding of arrays (and root-level sequences) of homogenous types
* [JACKSON-102]: Ability to force escaping of non-ASCII characters; using
JsonGenerator.Feature.ESCAPE_NON_ASCII and JsonGenerator.setHighestNonEscapedChar
* [JACKSON-106]: Add '' which can be
registered with JsonFactory, JsonGenerator, to add fully customized
character escaping handling
(suggested by Scott A)

optional (and non-standard) support for numbers like 00006
(suggested by Bryce M)

creates ObjectNode for property if no value exists (similar to "upsert" (update-or-insert))
* [JACKSON-464]: Allow defining default mappings for abstract types, with
* [JACKSON-494]: Add support for format auto-detection (via JsonFactory); add
support for basic JSON, Smile (and as many modules as possible)
* [JACKSON-512]: Allow wrapping InputStream/Reader, OutputStream/Writer when
constructing JsonParser, JsonGenerator; JsonFactory allows registering
InputDecorator, OutputDecorator instances.
* [JACKSON-513]: Add methods for registering key serializers, deserializers,
via Module API
* [JACKSON-520]: Add minimal FormatSchema abstraction, passed through by ObjectMapper
to JsonGenerator, JsonParser; needed for supporting schema-based formats.
* [JACKSON-521]: Add support for new 'MapLikeType' and 'CollectionLikeType', to
support Map/Collection types of languages like Scala
* [JACKSON-523]: Allow passing actual type for TypeSerializer to use, to
force specific super type to be used (instead of a concrete sub type)

which allows implicit conversion from JSON scalars and Objects into single-element
collections/arrays (for interoperability with XML-to-JSON converers like Jettison)

registered with ObjectMapper to get more control over how handlers (serializers,
deserializers, type id resolver) are constructed.

order be alphabetic (by property name).
(suggested by Chris W)

Potential backwards compatibility issues (compared to 1.7.x):
* [JACKSON-523]: Added method "idFromValueAndType()" in TypeIdResolver interface,
which is needed to properly handle types such as InetAddress, TimeZone -- unfortunately
this would break custom TypeIdResolver instances.
* [JACKSON-551]: Addition of new methods to 'Serializers' and 'Deserializers' interfaces
means that existing code (1.7 only) that directly implements interfaces will not compile
(i.e. source and binary incompatible change)

versions 1.1 - 1.5 accidentally had fields at lower precedence. This fix can
change behavior of code.

* [JACKSON-109] Allow deserializing into generics Bean classes
(like Wrapper<Bean>) not just generic Maps and Collections
* [JACKSON-121] Problems deserializing Date values of some ISO-8601
variants (like one using 'Z' to indicate GMT timezone)
* [JACKSON-122] Annotated serializers and deserializers had to
be public classes with public default constructor; not any more.
* [JACKSON-111] Added "jackson-xc" jar to contains XML Compatibility
New features:
* [JACKSON-70] Add support for generating JSON Schema
* [JACKSON-98] Allow serializing/deserializing field-accessible properties,
in addition to method-accessible ones.
* [JACKSON-105] Allow suppressing output of "default values"; which
means value of a property when bean is constructed using the default
no-arg constructor
(requested by Christoph S)
* [JACKSON-119] Add (optional) support for using JAXB annotations
(by using JaxbAnnotationIntrospector)
(requested by Ryan H)
* [JACKSON-120] Add annotations @JsonSerialize, @JsonDeserialize,
to streamline annotation by replacing host of existing annotations.
* [JACKSON-123] Add "chaining" AnnotationIntrospector (implemented
as inner class, AnnotationIntrospector.Pair) that allows combining
functionality of 2 introspectors.
1.0.1 [04-Jun-2009]
* [JACKSON-104] Build fails on JDK 1.5, assorted other minor issues
(reported by Oleksander A)
* [JACKSON-121] Problems deserializing Date values of some ISO-8601
variants (like one using 'Z' to indicate GMT timezone)
1.0.0 [09-May-2009]
* [JACKSON-103] Serializing Groovy objects; need to exclude getter method
"getMetaClass" from serialization to prevent infinite recursion
(reported by Ray T)
* Removed JAX-RS META-INF/services - based auto-registration for
JAX-RS MessageBodyReader/MessageBodyWriter, because it could
conflict with other application/json content handlers.
0.9.9-6 [27-Apr-2009]
* Improved jax-rs provider integration with jersey; now properly
auto-registers as handler for json media type(s), and allows
for defining custom ObjectMapper to be injected.
0.9.9-5 [20-Apr-2009]
New features:
* [JACKSON-88]: Support for "Setter-less" collection (and Map) types
* [JACKSON-100]: Allow specifying that BigInteger should be used instead
of Integer or Long for "generic" integral numeric types (Object, Number)
* [JACKSON-101]: Allow disabling of access modifier overrides
to support more security-constrainted running environments.
0.9.9-4 [14-Apr-2009]
* [JACKSON-94] Added missing "JsonParser.readValueAsTree()" method.
* JacksonJsonProvider was using strict equality comparison against
JSON type; instead needs to use "isCompatible". There were other
similar problems
(reported by Stephen D)
* [JACKSON-97] Generic types (with bound wildcards) caused problems
when Class introspector could not figure out that a concrete method
was overriding/implementing generic method; as well as having
problems with synthetic bridge methods.
* [JACKSON-95] Added support for deserializing simple exceptions
(Throwable and its sub-classes): anything with a String constructor
(assumed to take "message") should work to some degree.
* [JACKSON-99] IOExceptions should not be wrapped during object
(reported by Eldar A)
New features:
* [JACKSON-85]: Make Date deserialization (more) configurable (add
* [JACKSON-93]: Allow overriding the default ClassIntrospector.
* [JACKSON-96]: Allow enabling pretty-printing with data binding,
through SerializationConfig object.
0.9.9-3 [03-Apr-2009]
* [JACKSON-79]: Primitive value deserialization fragile wrt nulls
* [JACKSON-81]: Data binding code could lead to unnecessary blocking
because it tried to advance parser (and stream) after binding
(reported by Eldar A)
New features:
* [JACKSON-61]: Allow suppressing writing of bean properties with null values
(requested by Justin F)
* [JACKSON-63]: Create CustomDeserializerFactory to allow for adding
custom deserializers for non-structured/generic types.
* [JACKSON-75]: Add "any setter" method; ability to catch otherwise
unknown (unmapped) properties and call a method with name+value.
* [JACKSON-80]: Add @JsonValue annotation, to specify that a Bean value
is to be serialized as value returned by annotated method: can for
example annotate "toString()" method.
* [JACKSON-84]: Added JsonGenerator.writeRawValue methods to augment
existing JsonGenerator.writeRaw() method
(requested by Scott A)
* [JACKSON-86]: Added JsonParser.isClosed() and JsonGenerator.isClosed()
* [JACKSON-87]: Added ability to customized Date/Calendar serialization,
both by toggling between timestamp (number) and textual (ISO-8601),
and by specifying alternate DateFormat to use.
0.9.9-2 [19-Mar-2009]:
* [JACKSON-75]: Didn't have Deserializer for Number.class.
* [JACKSON-68]: Add DeserializationProblemListener, and
DeserializationConfig.addHandler to add instances to ObjectMapper.
* [JACKSON-71]: Add support ser/deser of Class.class.
* [JACKSON-72]: Allow specifying that BigDecimal should be used instead
of Double for "generic" numeric types (Object, Number)
* [JACKSON-73]: Refactored ser/deser configuration settings into
separate configuration classes.
* [JACKSON-78]: Should be able to deserialize ints into Booleans (0 == false)
New features:
* [JACKSON-45]: Add convenience methods to help writing custom
(requested by Scott A)
0.9.9 [02-Mar-2009]:
* [JACKSON-59]: NPE with String[] serializer
(reported by Kevin G)
* [JACKSON-62]: NPE with JsonMappingException if source exception used
null message.
(reported by Justin F)
* [JACKSON-64]: Handling of property name (with @JsonGetter, @JsonSetter)
made bit more intuitive; uses bean naming convention if no explicit
name given.
* [JACKSON-60]: Method annotations did not follow intuitive expectations
of inheritability; now do.
* [JACKSON-65]: Need to support typing using "java.lang.reflect.Type", to
help integration with frameworks.
* [JACKSON-66]: ObjectMapper now has "canSerialize" and "canDeserialize"
methods to help frameworks figure out what is supported.
New features:
* [JACKSON-52]: Allow disabling name-based auto-detection of
getter methods
(requested by Justin F)
* [JACKSON-58]: Allow defining custom global Enum serializer
(to, for example, make Enums be serialized using Enum.toString(),
or lower-case name or such)
* [JACKSON-67]: Add JAX-RS provider based on Jackson that can handle
JSON content type; initially as a separate jar.
* [JACKSON-22]: all contributors now have submitted contributor
agreement, stored under 'DEV/agreements-received' in svn trunk.
0.9.8 [18-Feb-2009]:
* [JACKSON-49]: Incorrect bounds check for Float values resulted in
exception when trying to serializer 0.0f.
New features:
* [JACKSON-32]: add annotations to configure serialization process
(@JsonClass/@JsonContentClass/@JsonKeyClass; @JsonUseSerializer,
@JsonUseDeserializer, @JsonIgnore)
* [JACKSON-36]: add annotations to define property names that differ
from bean naming convention (@JsonGetter/@JsonSetter)
* [JACKSON-47]: Change DeserializerProvider.findValueDeserializer to
take "referrer" information. This is needed to be able to give
contextual mappings where a given type may be deserialized differently
(by different deserializer, and possibly to a different java class)
depending on where the reference is from.
* [JACKSON-48]: Integrate ObjectMapper with JsonGenerator, JsonParser;
add MappingJsonFactory.
(suggested by Scott A)
* [JACKSON-50]: JsonNode.getElements() and .iterator() now work for
ObjectNodes too, not just ArrayNodes. Also added convenience factory
methods to allow constructing child nodes directly from container
* [JACKSON-53]: iBatis proxied value classes didn't work; fixed by
prevent CGLib-generated "getCallbacks" from getting called.
(reportd by Justin F)
* [JACKSON-55]: Added support for reference-path-tracking in
JsonMappingException, made serializers populate it: this to make
it easier to trouble-shoot nested serialization problems
* [JACKSON-56]: Added support for RFC-1123 date format, along with
simpler "standard" format; and can add more as need be.
0.9.7 [04-Feb-2009]:
* [JACKSON-34]: Improved packaging by adding an intermediate directory
in source tarball, to not mess up the current directory (and to indicate
version number as well)
* [JACKSON-37]: Make Jackson run on Android, by ensuring that there are
no hard linkages to classes that Android SDK doesn't have (the only
reference that was there, to XMLGregorianCalendar, was changed to
soft linkage)
* [JACKSON-42]: Add new JsonNode sub-class, BinaryNode, to represent
base64 encoded binary content.
New features:
* [JACKSON-6]: Implement JsonParser.getBinaryValue() so that one can
now also read Base64-encoded binary, not just write.
* [JACKSON-40]: Add JsonParser.nextValue() for more convenient
* [JACKSON-46]: Allow disabling quoting of field names by disabling
feature 'JsonGenerator.feature.QUOTE_FIELD_NAMES'
(requested by Scott Anderson)
0.9.6 [14-Jan-2009]:
Bug fixes:
* Serialization of some core types (boolean/java.lang.Boolean,
long/java.lang.Long) was not working due to incorrectly mapped
New features:
* [JACKSON-31]: Complete rewrite of ObjectMapper's deserialization:
now supports Beans, typed (generics-aware) Lists/Maps/arrays.
* [JACKSON-24]: Add efficient byte-array - based parser factory
method to JsonFactory (has maybe 5% improvement over wrapping
in ByteArrayInputStream).
* [JACKSON-29]: Split classes in 2 jars: core that has parser and
generator APIs and implementations; and mapper jar that has object
and tree mapper code.
* [JACKSON-30]: Renamed "JavaTypeMapper" as "ObjectMapper", and
"JsonTypeMapper" as "TreeMapper"; new names should be more intuitive
to indicate their purpose. Will leave simple implementations of
old classes to allow for gradual migration of existing code.
0.9.5 [10-Dec-2008]:
Bug fixes:
* [JACKSON-25]: Problems with Maven pom for lgpl version
(report by Ray R)
note: backported to 0.9.4 Codehaus Maven repo
* [JACKSON-13]: JavaTypeMapper can now take JsonFactory argument, and
thus is able to construct JsonParser/JsonGenerator instances as necessary
* [JACKSON-17]: Handling of unknown types now configurable with
JavaTypeMapper serialization (see JsonSerializerProvider for methods)
* [JACKSON-20]: Handling of nulls (key, value) configurable with
JavaTypeMapper serialization (see JsonSerializerProvider for methods)
* [JACKSON-26]: Add convenience JsonGenerator.writeXxxField() methods
to simplify json generation.
New features:
* [JACKSON-27]: Allow automatic closing of incomplete START_ARRAY and
START_OBJECT events, when JsonGenerator.close() is called.
0.9.4 [26-Nov-2008]:
Bug fixes:
* [JACKSON-16]: JavaDocs regarding whether Jackson is to close underlying
streams, readers and writers, were incorrect. Additionally added
parser/generator features to allow specifying whether automatic closing
is to be done by Jackson: feature is enabled by default, both for
backwards compatibility, and because it seems like the right setting.
* [JACKSON-18]: ArrayIndexOutOfBounds on IntNode, due to off-by-one
problem with comparisons
(reported by Michael D)
* Fixed a problem with CR (\r) handling; was sometimes skipping
characters (problematic if there's no indentation).
* Multiple UTF-8 decoding fixes: was specifically not working for
* More complete JavaDoc comments for core public classes.
* Internal cleanup of core parsing, to unify handling of Object and
Array entries
0.8.0 - 0.9.3 [between 17-Oct-2007 and 05-Sep-2008]:
* [JACKSON-5]: Symbol table construction was not thread-safe for
utf-8 encoded content (new bug with 0.9.2, not present with earlier)
(reported by Tudor B)
* [JACKSON-8]: Serialization of BigDecimal broken with JavaTypeMapper
(reported by Johannes L)
* [JACKSON-9]: Add support for (non-standard) Json comments.
(requested by Mike G)
* [JACKSON-11]: Implement base64/binary methods for json generator.
* [JACKSON-14]: Problems with generic collections, serializer
method signatures (due to lack of covariance wrt collection types)
* [JACKSON-15]: Add copy-through methods to JsonGenerator for
pass-through copying of content (copyCurrentEvent, copyCurrentStructure)
* [JACKSON-23]: Add OSGi manifest headers for jars (to run on OSGi container).
* Added generic "feature" mechanism to parsers, writers; features are
togglable (on/off) things with well-defined default values, implemented
as Enums.
* [JACKSON-1]: JsonNode now implements Iterable<JsonNode> so that
it is possible use Java 5 foreach loop over array/object nodes.
(suggested by Michael M)
* [JACKSON-4] Added JsonParser.skipChildren() method.
* UTF-16/32 handling was not completely correct, was erroneously
skipping first 2/4 bytes in some cases (even when no BOM included).
Also, related unit tests added/fixed.
* JsonGenerator.useDefaultPrettyPrinter()/.setPrettyPrinter()
allow for pretty printing (indentation).
(thanks to Ziad M for suggestion, sample code)
* Implicit conversions for numbers could sometimes lose accuracy,
if floating-point number was first accessed as int/long, and then
as a BigDecimal.
* One Nasty NPE fixed from NameCanonicalizer (which was added in 0.9.2)
* Java type mapper had a bug in Collection mapping (mismatched
calls between writeStartArray and writeEndObject!)
(reported by Mike E)
* Java type mapper had a bug which prevented custom mappers (as
well as slower interface-based introspection) from working.
(reported by Mike E)
* Numeric value parsing had some problems
* JavaTypeMapper and JsonTypeMapper had a bug which resulted
in NullPointerException when stream ends, instead of returning
null to indicate it.
(reported by Augusto C)
* JavaTypeMapper did not implicitly flush generator after mapping
objects: it should, and now will (note: JsonTypeMapper not directly
affected, flushing still needed)
