The XStream Development Team is proud to present XStream 1.2.1.

XStream is a simple library to serialize objects to XML and back again.

This is a maintenance release of XStream that contains a lot of bug fixes and has some minor highlights:

• JSON serialization and deserialization support with the help of the new JettisonMappedXmlDriver
• Supports customized field sorting
• Omitting fields at deserialization time

See more changes and download it.

Note, that next version of XStream will behave slightly different by default. XStream emits all fields in declaration order like Java serialization. But in contrast to Java it will omit the fields of parent classes last while Java serialization emits them first. This makes it difficult to match a given XML schema that defined inherited types or leads sometimes to obscure initialization problems. However, XStream itself will not be affected by the changed order of elements in the XML, any deserialization of current XML representations will work fine. Anyway we will provide with XStream 1.3 a FieldKeySorter implementation that mimics the old behaviour. In the meanwhile you can enforce the new field sorting by installing the NaturalFieldKeySorter.
