API breaking

Routing Slip now requires using Expression to specify the routing slip header, the XML DSL of Routing Slip is broken.

    <route>
       <from uri="direct:a"/>
       <!--NOTE from Camel 2.4.0, you need to specify the expression element inside of the routingSlip element -->
       <routingSlip ignoreInvalidEndpoints="true">
           <header>myHeader</header>
       </routingSlip>
    </route>

Known Issues

The Tracer may not output all details for some situations such as when using onCompletion or intercept etc.

Not all Examples have ANT build.xml files to run the example using ANT.

Important changes to consider when upgrading

IntrospectionSupport has been improved to be consistent for getProperty and getProperties. Also getProperties now find all relevant properties. This will often only be relevant for Camel end users who build their own components any may use IntrospectionSupport.

The ProducerTemplate have been tighten up a bit. All send/request -body methods will now throw a CamelExecutionException with the cause wrapped. This ensures its consistent. However the send/request methods (which returns an Exchange) will not throw an exception on failure. The caused exception is stored on the returned Exchange which you can access using the getException method.

The ftps is now using secure data channel also when transferring files. There has been added some options which you can use to control the behavior and turn it off if you want the old behavior (only secure login).

The default port from ftps has been changed from 2222 to 21.
