Finally, this release would not have been possible without the great
Jackson community. Although the full credits can be found at:

https://github.com/FasterXML/jackson-databind/blob/master/release-notes/CREDITS-2.x

there is also a new Acknowledgments page further outlining some of contributors:

Thank you for your help anyone who contributed something, be it a word
of encouragement, bug report or a PR.

And let us know how things are (or are not) working.
