+=== Jackson 3 components
+
+Four new components have been added which provide Jackson 3 support - they are
named similarly to the previously existing camel-jackson components. Jackson
3 operates under a different package name (tools.jackson.* vs.
com.fasterxml.jackson) and there are a number of API changes between Jackson 2
and Jackson 3 - see the
https://github.com/FasterXML/jackson/blob/main/jackson3/MIGRATING_TO_JACKSON_3.md[Jackson
Migration Guide] for details.

+The camel-jackson3 component shares a unified DSL with the camel-jackson
component under the "jackson" name. DefaultDataFormatResolver and
DefaultTransformerResolver resolve which Jackson library version is available
on the classpath and choose the appropriate data format or transformer. This
allows easy migration from the camel-jackson component to the camel-jackson3
component and a consistent interface between the two.
+
+The same detection mechanism and combined interface extends to the other
Jackson data formats (avroJackson, protobufJackson, and jacksonXml).

Support for exporting to use Gradle as build tool has been removed (it was
deprecated and not working well)
