Currently, there are around 26 components planned that will be removed from Camel 4.0:
https://camel.apache.org/manual/camel-4-migration-guide.html Maybe something to consider: 1. Deprecate those components already in 3.21.x 2. If the component has been renamed or has an alternative (say ActiveMQ --> SJMS, RabbitMQ --> AMQP) then it would be nice if they are listed in a table and this is mentioned in a separate column with a link to the alternative component. This will make upgrading easier for a lot of people. Raymond
