  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.

  use of separate Builder object for data binding, creating actual value
* [JACKSON-608]: Allow use of JSON Views for deserialization
* [JACKSON-636]: Add 'SerializationFeature.ORDER_MAP_ENTRIES_BY_KEYS' to allow
  forced sorting of Maps during serialization
  (suggested by Joern H)
