h2. New and Noteworthy

Welcome to the 2.2.0 release which approx XXX issues resolved (new features, improvements and bug fixes such as...)

* [Routing Slip] now breaks when an exception occurred
* [Mina] now supports easier configuration of multiple custom codecs, which is needed when working with SSL.
* Improved [TransactionErrorHandler] two fold by reducing complexity of internal logic in Camel when working with transactions. And added better support for using multiple transactions in multiple routes. See more at section _Using multiple routes with different propagation behaviors_ at [Transactional Client].
* [Recipient List] now supports {{parallelProcessing}}, {{stopOnException}} and references for {{AggregationStrategy}} and thread pools. This applies to the {{@RecipientList}} annotation as well.
* Cleanup of spring jar dependencies.
* [File Language] is now merged directly into [Simple] language which among others makes [Content Based Router] in Spring XML using file language syntax easier.
* Fixed [Camel Proxy|Using CamelProxy] throwing exception if {{null}} was returned.
* Improved error handling with [Recipient List] and [Multicast] which now performs redelivery etc. on that _output_ node instead of starting again from the scratch.
* [SEDA] now supports {{multipleConsumers}} which allows you to use it for pub-sub messaging where each consumer concurrently will receive a copy of the [Exchange]. This is done with the help from [Multicast] EIP.

h2. API breaking

h3. DefaultComponent

The methods {{DefaultComponent.resolveAndRemoveReferenceParameter}} and {{DefaultComponent.resolveAndRemoveReferenceParameterList}} have been changed to make the leading {{#}} sign for bean references optional and to throw an {{IllegalArgumentException}} if a referenced bean is not in the registry. For details see [CAMEL-2248|https://issues.apache.org/activemq/browse/CAMEL-2248].

h3. Exchange
The property {{Exchange.FILTETED}} have been removed as part of [CAMEL-2288|https://issues.apache.org/activemq/browse/CAMEL-2248].

h2. Known Issues

See known issues from previous releases.

h2. Important changes to consider when upgrading

h3. Spring jar dependencies have been cut down in camel-core.
The {{pom.xml}} file for *camel-core* have cut down number of spring jar dependencies to allow Camel to easily run without any Spring .jars at all. However this affects you if you use maven and use camel-core without camel-spring or spring at all. If you want to use JMX with Camel then you need to add the following 4 spring jars required: {{spring-core.jar, spring-beans.jar, spring-context.jar, spring-aop.jar}}. With maven you only need to depend on {{spring-context}} and {{spring-aop}} as they will bring in the other two jars.

See also [Camel Jar Dependencies] and [Camel JMX].

h3. Using filter in [Splitter]
The {{filter}} no long influence the {{split}} and its {{AggregationStrategy}} as it was just too confusing why it did that. See [CAMEL-2288|https://issues.apache.org/activemq/browse/CAMEL-2248] for details.
