+### Main class
+
+The `Main` class from `camel-core`, `camel-spring` and `camel-cdi` has been
modified to only support a single `CamelContext` which was really its
intention, but there was some old crufy code for multiple Camels. The method
`getCamelContextMap` has been removed, and there is just a `getCamelContext`
method now.

### Moved APIs
The following API changes may affect your existing Camel applications, which
needs to be migrated.
