Release 1.3 of JacksonHome (code name "Great Pumpkin") was released October 30th 2009. It is classified as a "minor" update over JacksonRelease11, since it will be fully backwards compatible (hence not a "major" version bump), but will introduce number of new features (hence not a "patch" release -- although "Pumpkin Patch" would be an apt term, maybe use that for 1.3.1).
Following is the list of significant improvements release contains.
Check out complete http://jackson.codehaus.org/1.3.0/release-notes/VERSION for full list of changes)
- http://jira.codehaus.org/browse/JACKSON-129 Allow constructing JsonParser to read from JsonNode (JacksonTreeModel): can be used for binding JSON Trees as Java objects, similar to how textual JSON content can be bound to objects
- http://jira.codehaus.org/browse/JACKSON-159: Added org.codehaus.jackson.jaxrs.JacksonJaxbJsonProvider for easier use of JacksonJAXBAnnotations with JAX-RS.
- http://jira.codehaus.org/browse/JACKSON-174: Added ObjectMapper.convertValue() for convenient conversions between compatible (but not necessarily Java castable!) types -- functionally identical to serializing from source value to JSON, deserializing to target type, but more efficient.
- http://jira.codehaus.org/browse/JACKSON-152: Convenience method (ObjectMapper.writeValueAsString()) to simplify serializing Java objects as JSON Strings.
- http://jira.codehaus.org/browse/JACKSON-153: Allow use of @JsonCreator with Map types too
- http://jira.codehaus.org/browse/JACKSON-154: Added .keyUsing and .contentUsing for JsonDeserialize annotation, to allow specifying deserializer to use for key and content/value types of structured-value (Collection, Map, array) properties
- http://jira.codehaus.org/browse/JACKSON-158: Simple checking for self-references (tight cycle) during serialization, instead of waiting for StackOverflowError
- http://jira.codehaus.org/browse/JACKSON-165: Add JsonParser.getBooleanValue() convenience method
- http://jira.codehaus.org/browse/JACKSON-173: Add feature JsonParser.Feature.ALLOW_SINGLE_QUOTES to allow parsing invalid JSON content that uses single-quotes (apostrophes) instead of double quotes
- http://jira.codehaus.org/browse/JACKSON-176: Added JsonGenerator.Feature.WRITE_NUMBER_AS_STRINGS as a workaround for Javascript problems with big longs (due to always representing numbers as 64-bit doubles internally)
- http://jira.codehaus.org/browse/JACKSON-180: Added JsonParser.Feature.INTERN_FIELD_NAMES to allow disabling field name intern()ing.
- Deserialization:
- http://jira.codehaus.org/browse/JACKSON-167: Generic type information lost for Maps and Collections
- http://jira.codehaus.org/browse/JACKSON-179: Single-argument constructor Creators sometimes not found (reported for long arguments)
- http://jira.codehaus.org/browse/JACKSON-183: Root-level Bean annotations not handled completely
- OSGi packaging:
- http://jira.codehaus.org/browse/JACKSON-162: Jackson-xc module's dependencies were incorrectly declared.
- http://jira.codehaus.org/browse/JACKSON-138: Add support for JacksonJsonViews (using @JsonView annotations)
- Will be the first new thing to be added for 1.4...
- http://jira.codehaus.org/browse/JACKSON-137: Allow use of proxy object to simplify handling of generic objects -- will possibly add "Jackson Sandbox" to first introduce this clever construct?
- http://jira.codehaus.org/browse/JACKSON-163: Support "wrapped" output for JAXB compatibility: additional dummy Map with a single key (from JAXB @XmlRootElement annotation), used to make output more similar to XML output.
