release-notes/VERSION

Version: 2.1.0

Release date:
  xx-Jun-2012

Description:
  New minor version for 2.x.

Fixes:

* [JACKSON-830]/[Issue-19]: Change OSGi bundle name to be fully-qualified
* Minor fix wrt [Issue-11], coercion needed extra checks

Improvements:

* [JACKSON-839]: Allow "upgrade" of integer number types for
  UntypedObjectDeserializer, even with default typing enabled.
* [Issue-9]: Implement 'required' JSON Schema attribute for bean properties
* [Issue-22]: Add 'ObjectMapper.setAnnotationIntrospectors()' which allows
  defining different introspectors for serialization, deserialization
* ObjectReader and ObjectWriter now try to pre-fetch root (de)serializer if
  possible; minor performance improvement (2% for small POJOs).
* Added 'ObjectReader#withHandler' to allow for reconfiguring deserialization
  problem handler
 (suggested by 'electricmonk')

Other changes:

* New variant of AnnotationIntrospector.getFormat(), to support class
  annotations
* It is now possible to serialize instances of plain old Object, iff
  'FAIL_ON_EMPTY_BEANS' is disabled.
