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-20]: Add new exception type, InvalidFormatException (sub-type of
  JsonMappingException) to indicate data format problems
 (suggested by HolySamosa@github)
* [Issue-22]: Add 'ObjectMapper.setAnnotationIntrospectors()' which allows
  defining different introspectors for serialization, deserialization
* [Issue-30] ObjectReader and ObjectWriter now try to pre-fetch root (de)serializer
  if possible; minor performance improvement (2% for small POJOs).
* [Issue-33] Simplified/clarified definition of 'ObjectReader.readValues()';
  minor change in behavior for JSON Array "wrapped" sequences
* 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.

INCOMPATIBILITIES: (rats!)

* Note that [Issue-33] (see above) is, technically speaking, backwards
  imcompatible change. It is estimated that it should NOT affect most
  users, as changes are to edge cases (and undocumented ones at that).
  However, it can potentially cause problems with upgrade.
