This page outlines some of contributors that contributed to Jackson 2.12: it is not an exhaustive list but summarizes some of larger features. List is no almost certainly incomplete (apologies to anyone whose contribution is accidentally left out) as well as subjective -- no feature is insignificant, and omission from here (intentional or accidental) is not meant as value judgment.

Special thank you note to following module maintainers (existing and new) for their contributions (in alphabetic module order):

• Java 8 date/time
• Kotlin
• Scala
