h2. New and Noteworthy
 
Welcome to the 1.4.0 release which includes: 192 tickets resolved (new features, improvements and bug fixes such as...)

* major improvements in [JMS] and [Mail] components
* JMS headers now preserve packagename style headers so [Bean] and [File] headers is preserved, so you can safely send the filename or bean method to invoke over the JMS wire.
* major improvements in [Camel JMX] management (enabled by default)
* [Transactional Client] improvements. Bypassing [DeadLetterChannel] redelivery, letting the originator system handle this. Meaning that a JMSMessage is rolled back to the JMS queue etc.
* various improvements in [CXF], [File], [FTP], [Velocity], [Stream] components
* various improvements in the Java and Spring DSL
* refinements to run in OSGi containers
* some internal refactorings of package structure to avoid cycle dependencies
* @deprecated some core classes, that will be removed in Camel 2.0
* improved feedback for misconfiguration of camel routes such as mistypes of parameters
* introduced [ExceptionPolicyStrategy|Dead Letter Channel] as strategy for exception clause selection during error handling (much improved default strategy in Camel)
* overall improved wiki documentation
* improved javadoc for camel-core
* attachment support for [Message]
* introduced [Debugger] and [Tracer] interceptor to track how exchanges is routed.

h2. API breakings

Potentially there can be an API breaking when upgrading from Camel 1.3 or older. We are sorry for this and will try to refrain from such API breakings in the future Camel 1.x releases. An API overhaul is scheduled for Camel 2.0.

h2. Known Issues

CamelTemplate has been marked as @deprecated and you should use ProducerTemplate instead.
From Camel 1.4.0 on the ProducerTemplate must be retrieved from the CamelContext. You can then use it the same way as before.
{code}
ProducerTemplate camelTemplate = camelContext.createProducerTemplate();
{code}

Bean component sets a reference to the bean that is being invoked as a property on the Exchange. This property has change its key from "CamelBean" to "org.apache.camel.bean.BeanHolder" and the type is now a BeanHolder.

Camel deployed as a web application in WebSphere 6.1 can not discover annotated converters.

h2. Important changes to consider when upgrading
In Camel 1.4 the [Camel JMX] agent has been enabled by default. To disable it, as the default in previous versions, you have to explicitly disable it. See the [Camel JMX] documentation for details.
