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.
| The Camel Upgrade Recipes project provides automated assistance for some common migration tasks. Note that manual migration is still required. See the documentation page for details. |
Upgrading Camel 4.16 to 4.17
camel-jbang
The camel-kamelets-catalog JAR is now downloaded on-demand. The version of the Kamelets is now specified via --kamelets-version option (or via maven dependencies). The following option is no longer in use -Dcamel-kamelets.version.
Removed automatic fallback to download Kamelet YAML files from GitHub. Instead, kamelets are now only loaded from embedded camel-kamelets JAR.
