h2. New and Noteworthy

Welcome to the 2.12.0 release which approx XXX issues resolved (new features, improvements and bug fixes such as...)

* [Endpoint Annotations] along with automatically created HTML documentation for the endpoint parameters; this makes it easier for component developers to add a few refactoring-safe annotations to their Endpoint or Consumer implementations and, (along with javadoc comments on the field or setter method), get nice user documentation on how to use the endpoint for free.
* [ComponentConfiguration] API provides a handy API for tools developers to introspect on a Component to find all the possible parameters, their types and any extra annotations (like Bean Validation Annotations) to be able to create/edit endpoints or URI strings so that tools can generate nicer UIs for configuring endpoints than just letting folks edit Strings.
* [EndpointCompleter] API provides a hook so that command line tools (like [Karaf's shell|http://karaf.apache.org/manual/latest-2.3.x/users-guide/using-console.html]), IDEs and web tools can get (bash tab like) auto-completion on endpoint paths (such as file or directory names, message queue names, database table names) when creating or using new endpoints
* Reduced stack-frames in use during routing, that also makes Camel's stack traces being logged much less verbose. This also allows people to easier debug the internals of Camel as less {{AsyncCallback}} callbacks are in use during routing.
* [Spring Web Services] now supports setting/receiving SOAP headers more easily using a header on the Camel [Message].
* Evaluating [Groovy] expressions is faster as we cache the compiled scripts.
* Added {{base64}} option to [Shiro Security] to allow transferring security token over [JMS] and other transports as base64 encoded representation.
* Made it easier to use [Shiro Security] as the credentials can be provided in headers, when sending a message to a secured route.
* [Bindy] now supports enums.
* Added new [BacklogDebugger] to perform live debugging of messages during routing. The [BacklogDebugger] has JMX API allows tooling to control the debugger.
* While using the [Jackson library|http://xircles.codehaus.org/projects/jackson] through the [JSON] Dataformat there's now a {{jsonView}} attribute you could make use of directly inside the [DSL] itself.

h3. Fixed Issues

* Fixed setting .id in Java DSL on some [EIP]s such as the [Validate]
* Fixed [Dead Letter Channel] always handled exception, which wasn't the case if an [Exception Clause] was in use, which didn't had handled=true.
* Fixed [Using PropertyPlaceholder] in attributes defined on {{<camelContext>}}.
* All Camel [Components] will configure their consumers when being created to ensure you can configure from [URIs] with {{consumer.}} as prefix.
* Fixed [QuickfixJEndpoint|Quickfix] to adhere a given InOut MEP correctly.
* Fixed using property placeholders in a [Simple] predicate used inside a when in a [Content Based Router] when using [Java DSL]

h2. Internal changes
* The following classes in {{org.apache.camel.processor}} has been removed as they are no longer needed due internal optimization: {{UnitOfWorkProcessor}}, {{ChildUnitOfWorkProcessor}}, {{RouteContextProcessor}}, {{RouteInflightRepositoryProcessor}}, and {{RoutePolicyProcessor}}

h2. Changes that may affect end users
* The [File|File2] and [FTP|FTP2] consumers when using idempotent repository will no longer invoke {{contains}} with a directory name; this has been changed to only be checked for files.
* Shutting down using [Graceful Shutdown] now requires the timeout value to be positive. And improved logic to avoid getting stuck in waiting for inflight messages, and having counter go negative.
* [Tracer] now requires explicitly to be enabled on {{CamelContext}} to be available and in use.
* The class {{org.apache.camel.processor.interceptor.BacklogTracerInterceptor}} has been removed as it was no longer needed due internal optimizations.

h2. Important changes to consider when upgrading
* Spring 3.0.x is no longer supported.
* The usage of the deprecated built-in {{CommonsHttpMessageSender}} has been replaced with {{HttpUrlConnectionMessageSender}} by [Spring Web Services]. Consider this in case either the {{timeout}} or {{sslContextParameters}} option is used through the Producer of this component.
* {{camel-scala-29}} module has been removed.
