Version history

  • 2019-02-10: create skeletal version

TL; DNR;

Prior Work

Note that at the time of writing (February 2019), some of the work has already been done. Attempt is made to include such changes in this plan as if work was being planned, even if initial changes have been made.

Changes to "Feature" defaults

MapperFeature

  • SORT_PROPERTIES_ALPHABETICALLY: default to true (false really doesn't make much sense since it is unstable, and arbitrary based on JVM/JDK)

DeserializationFeature

  • READ_ENUMS_USING_TO_STRING: default to true (instead of false that relies on name())
  • FAIL_ON_UNKNOWN_PROPERTIES: default to false? (TOP REQUEST by users)

SerializationFeature

  • FAIL_ON_EMPTY_BEANS: default to false

Changes to Date/Time defaults

  • Disable lenient setting (that is: default to "strict")
  • Check defaults of date/time handling

Misc other default setting, behavior changes

  • DecimalNode creation via JsonNodeFactory: default to NOT truncating trailing zeroes (minimal trimming), because JsonNode should by default expose content as close to way it came.
