Apache Camel 4.x Upgrade Guide

This document is for helping you upgrade your Apache Camel application from Camel 4.x to 4.y. For example, if you are upgrading Camel 4.0 to 4.2, then you should follow the guides from both 4.0 to 4.1 and 4.1 to 4.2.

Upgrading Camel 4.12 to 4.13

camel-core

Added a 2nd lookup method to org.apache.camel.spi.TypeConverterRegistry and changed the addConverter to no longer have an empty default noop implementation in the interface.

camel-http

Renamed class org.apache.camel.component.http.BasicAuthenticationHttpClientConfigurer to org.apache.camel.component.http.DefaultAuthenticationHttpClientConfigurer.

camel-yaml-dsl

The deprecated kebab-case has been removed. For example set-body and set-header should be setBody / setHeader etc.

Camel Spring Boot

Remove the deprecated camel.springboot.xxx configuration syntax. Use camel.main.xxx syntax which is standard across all runtimes.
