h2. New and Noteworthy

Welcome to the 2.3.0 release which approx XXX issues resolved (new features, improvements and bug fixes such as...)

* [Overhauled threading model|Threading Model] and introducing {{threadPoolProfile}} to define profiles for thread pools to have easy configuration.
* [Property placeholders|Using PropertyPlaceholder] in for example endpoint uris is not natively supported in *camel-core* which means you no long need to use Spring for that. It works therefore in any environment as its provided out of the box in camel-core.
* [Property placeholders|Using PropertyPlaceholder] also works in the {{<CamelContext>}} when using Spring XML. Basically nearly all places where you enter text the property placeholder is supported.
* Added {{ExchangeSentEvent}} to {{EventNotifier}} which contains time taken and is emitted when an [Exchange] is sent to an [Endpoint]. This allows end users to easily gather performance stats for [Exchange] send to endpoints.
* Added {{disconnect}} option to [Mina] to close Mina session right after usage. 
* [Jetty] now supports to get the {{HttpServletRequest}} and {{HttpServletResponse}} from the [Message] header.
* [XPathBuilder|XPath] now supports being used without an [Exchange] which allows you to use it in a custom/generic fashion.
* [XPath] now supports using the JVM system property specifying a custom {{XPathFactory}} to be used. You can use this to switch from default to use e.g. Saxon. 
* [XSLT] now supports using {{<xsl:include>}} where the files is loaded from classpath, and being able to load relative according to the endpoint configured location. See the wiki page for details. 
* [File|File2], [FTP|FTP2] added option {{eagerDeleteTargetFile}} to control the behavior when using {{tempFile}} whether or not to eagerly delete the target file or wait until last moment. 
* Reduced registering producers in JMX to prevent using too much memory and potentially registering short lived producers which didn't bring much value of being managed as well.
* Upgraded [HTTP] to use Apache HTTP Client 4.0.1. You may need to migrate if you use special or advanced configuration of HTTP Client.
* Upgraded [Jetty] to use Jetty 7.0.1.
* Individual routes can be [Graceful Shutdown] at runtime, which allows you to stop the route in a more reliable and gentle way.
* Total overhaul of the [Aggregator|Aggregator2] EIP, which now has better completion triggers, and supports pluggable repository. For example to use [camel-hawtdb|HawtDB] as persistent store.
* Added {{removeHeaders}} to remove multiple headers, e.g. use {{removeHeaders("Camel*")}} to remove all Camel related headers.
* Improved the [Failover load balancer|Load Balancer] to support round robin mode and a few other options as well.
* Fixed issue with Camel not being able to run deployed as a WAR in WebLogic server.
* Fixed [Polling Consumer] not working with [JMS] selector.
* [pollEnrich|Content Enricher] now handover completions which means you can use the {{move}} like options from [File or FTP|File2] component. For example to enrich with a file and have that file moved when the route completes.
* Added @Attachments annotation to Bean binding.
* [Simple] and [Bean] language now has a build in OGNL notation which allows you to reference from {{Map}} or {{List}} structures and as well to invoke methods in a OGNL like notation. See more details at [Simple] wiki page.
* [camel-jetty|Jetty] supports the multipart/form post out of box. 
* [Graceful Shutdown] now shut down routes in the reverse order in which they was started. Option {{shutdownRoutesInReverseOrder}} can be used to control this behavior.
* [Xslt] component now allows you to chose which output type to use with the {{output}} option. For example you can now stream directly to a file, for example when transforming very big xml messages.

h3. New [Enterprise Integration Patterns]

h3. New [Components]

* [camel-nagios|Nagios] for sending passive checks to [Nagios|http://nagios.org]
* [properties|Properties] for using property placeholders to resolve endpoint uris.
* [camel-gae|GAE] extensions
** [gauth] component for implementing [OAuth|http://code.google.com/apis/accounts/docs/OAuth.html] consumers.
** [glogin] component for programmatic login to Google App Engine applications from Java clients.
* [camel-hawtdb|HawtDB] as persistent store for the [Aggregator|Aggregator2] EIP.

h3. New DSL
* {{removeHeaders}}

h3. New Annotations
* {{@Attachments}}

h3. New [Data Formats|Data Format]

h3. New [Languages]

h3. New [Examples]
* [camel-example-aggregate|Aggregate Example] shows the new overhauled [Aggregator|Aggregator2] in use with persistence storage using [HawtDB].

h2. API breaking

The [Aggregate|Aggregator2] has been overhauled and thus you need to migrate you Camel application if you use it.
See the [Aggregate|Aggregator2] wiki page for which options it has you should use.

In [Mina] the header key {{MinaConsumer.HEADER_CLOSE_SESSION_WHEN_COMPLETE}} is moved to {{MinaConstants.MINA_CLOSE_SESSION_WHEN_COMPLETE}} 

{{org.apache.camel.spi.PollingConsumerPollStrategy}} now returns a boolean in the {{begin}} method. Use {{true}} to accept to begin polling, and {{false}} to skip polling at this time.

A new method {{onInit}} has been added to {{org.apache.camel.spi.RoutePolicy}}.

Added method {{removeHeaders}} on the {{org.apache.camel.Message}} API.

{{getExecutorService/setExecutorService}} have been removed from {{DefaultComponent}} and {{DefaultEndpoint}}.
You should use {{CamelContext.getExecutorServiceStrategy()}} which is the API for creating thread pools in Camel.

Changed {{Exception}} to {{Throwable}} on the {{org.apache.camel.spi.EventFactory}} and the various {{xxxEvent}} objects as Camel now catches {{Throwable}} on shutdown to ensure a more robust shutdown in case a {{Throwable}} was thrown.

h2. Known Issues

No known issuesThe [Tracer] may not output all details for some situations such as when using {{onCompletion}} or {{intercept}} etc.

h2. Important changes to consider when upgrading

The [SEDA] endpoint is now by default unbounded in size, where as before they had a default size of 1000.

[camel-http|HTTP] has been upgraded to use Apache HTTP Client 4.0.1 from 3.1. These two versions is much different how to configure, so you may have to migrate if you do any special or advanced configuration. Consult the [Apache HTTP Client documentation|http://hc.apache.org/httpcomponents-client/tutorial/html/]. 

[camel-jetty|Jetty] has been upgraded to use Jetty 7.0.1 from 6.1.22. These two versions is much different as 7.x is moved to be hosted at Eclipse, which means all it package names has been renamed.
