Apache Camel 3.x Upgrade Guide
This document is for helping you upgrade your Apache Camel application from Camel 3.x to 3.y. For example if you are upgrading Camel 3.0 to 3.2, then you should follow the guides from both 3.0 to 3.1 and 3.1 to 3.2.
Upgrading Camel 3.19 to 3.20
camel-api
The org.apache.camel.support.jsse.SSLContextParameters is now using ResourceLoader from CamelContext
to load keystore and other resources in a standard way. Therefore, the SSLContextParameters now must have been pre-configured
with a CamelContext otherwise an exception is thrown.
camel-jsonpath
There is a new option unpackArray that unpacks a single-element Json array, matched by a Jsonpath, into an object. This option is disabled by default (this behaviour was enabled by default in previous Camel versions). There is a new expression jsonpathUnpack(String text, Class<?> resultType) that makes use of this new option.
