h2. New and Noteworthy

Welcome to the 2.9.0 release which approx XXX issues resolved (new features, improvements and bug fixes such as...)

* Reduced the API in thread pool management for Camel component developers. See [CAMEL:Threading Model] for more details.
* Fixed issue with [Properties] component may cache duplicates and thus take up unnecessary memory in the cache
* Fixed issue with [Tracer] out exchanges when using [Asynchronous Processing] by the [Asynchronous Routing Engine]
* Fixed issue with [Component]s or [Endpoint]s not being registered in [JMX|Camel JMX] when using [POJO Producing], [POJO Consuming] or other Camel bean annotations.
* The [Bean] component now supports specifying parameter values to use directly in the method syntax. See more details at [Bean Binding]. For example to invoke a bean with body as first parameter, and a boolean true as second you can now do: {{.to("bean:myBean?method=myMethod(body, true)")}}
* Fixed issue which could cause {{DefaultUnitOfWork}} to throw a {{java.util.EmptyStackException}} under heavy load
* Improved labels of all model definitions which appear in [Tracer] output
* Fixed issue with [MDC logging] not remembering old values, for example when using a {{ProducerTemplate}} from within routes to send new messages.
* Reduced dependency for {{camel-core}} to not require {{commons-management}} JAR anymore
* Added blueprint support of cxfrs endpoint.
* Camel no longer depend on using Spring JARs for having Camel enlisted in [JMX|Camel JMX].
* Introduced a set of Camel JMX annotations in {{org.apache.camel.management}} that can be used to easily instrument Camel [Components], [EIP]s, custom [Processor]s, [Bean]s etc. for being managed in [JMX|Camel JMX]. Using the Spring JMX annotations is still supported (you would need {{camel-spring}} on the classpath).
* Fixed issue when invoking a [Bean] and that bean is using a {{@Bean}} in its method signature, causing the {{@Bean}} to not invoke its intended method
* Updated the [Aggregator2] to allow for manually completing all exchange groups by sending a message containing the header {{Exchange.AGGREGATION_COMPLETE_ALL_GROUPS}} set to true.
* Fixed issue with [Bindy] unmarshalling in key value mode when using @OneToMany bindings, may cause inconsistency for multiple threaded unmarshalling 
* Removed dependency on Spring JARs in the following components: [Validation], [XSLT], [Velocity], [Freemarker], [Flatpack], [StringTemplate], [iBatis], [Jing], [Msv], and [MsvXQuery]
