+should match. That means you should use at least bson4jackson 2.1
 if you use Jackson 2.1, bson4jackson 2.2 if you use Jackson 2.2, etc.
 I will try to keep bson4jackson up to date. If there is a compatibility
-issue I will update bson4jackon, usually within a couple of days after
-the new Jackson version has been released.
