Camel has upgraded from Spring Boot v1 to v2 and therefore v1 is no longer supported.
Upgraded to Spring Framework 5. Camel should work with Spring 4.3.x as well, but going forward Spring 5.x will be the minimum Spring version in future releases.
Upgraded to Karaf 4.2. You may run Camel on Karaf 4.1 but we only officially support Karaf 4.2 in this release.
Optimised using toD DSL to reuse endpoints and producers for components where its possible. For example HTTP based components will now reuse producer (http clients) with dynamic uris sending to the same host. See more details in the toD documentation.
The File2 consumer with read-lock idempotent/idempotent-changed can now be configured to delay the release tasks to expand the window when a file is regarded as in-process, which is usable in active/active cluster settings with a shared idempotent repository to ensure other nodes dont too quickly see a processed file as a file they can process (only needed if you have readLockRemoveOnCommit=true).
