<h2><a name="Camel2.12.0Release-NewandNoteworthy"></a>New and Noteworthy</h2>

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

	<li><a href="/confluence/display/CAMEL/Endpoint+Annotations" title="Endpoint Annotations">Endpoint
Annotations</a> 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.</li>
	<li><a href="/confluence/display/CAMEL/ComponentConfiguration" title="ComponentConfiguration">ComponentConfiguration</a>
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.</li>
	<li><a href="/confluence/display/CAMEL/EndpointCompleter" title="EndpointCompleter">EndpointCompleter</a>
API provides a hook so that command line tools (like <a href=""
class="external-link" rel="nofollow">Karaf's shell</a>), 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</li>
	<li>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 <tt>AsyncCallback</tt> callbacks are in use during routing.</li>
	<li>Easy to use <a href="/confluence/display/CAMEL/Message+History" title="Message
History">Message History</a> out of the box. And included message history as "route
stack-trace" when exceptions logged by <a href="/confluence/display/CAMEL/Error+Handler"
title="Error Handler">Error Handler</a> to make it easier for end users to spot where
the exception occurred.</li>
	<li><a href="/confluence/display/CAMEL/Spring+Web+Services" title="Spring Web Services">Spring
Web Services</a> now supports setting/receiving SOAP headers more easily using a header
on the Camel <a href="/confluence/display/CAMEL/Message" title="Message">Message</a>.</li>
	<li>Evaluating <a href="/confluence/display/CAMEL/Groovy" title="Groovy">Groovy</a>
expressions is faster as we cache the compiled scripts.</li>
	<li>Added <tt>base64</tt> option to <a href="/confluence/display/CAMEL/Shiro+Security"
title="Shiro Security">Shiro Security</a> to allow transferring security token over
<a href="/confluence/display/CAMEL/JMS" title="JMS">JMS</a> and other transports
as base64 encoded representation.</li>
	<li>Made it easier to use <a href="/confluence/display/CAMEL/Shiro+Security" title="Shiro
Security">Shiro Security</a> as the credentials can be provided in headers, when
sending a message to a secured route.</li>
	<li><a href="/confluence/display/CAMEL/Bindy" title="Bindy">Bindy</a> now
supports enums.</li>
	<li>Added new <a href="/confluence/display/CAMEL/BacklogDebugger" title="BacklogDebugger">BacklogDebugger</a>
to perform live debugging of messages during routing. The <a href="/confluence/display/CAMEL/BacklogDebugger"
title="BacklogDebugger">BacklogDebugger</a> has JMX API allows tooling to control
the debugger.</li>
	<li>While using the <a href="" class="external-link"
rel="nofollow">Jackson library</a> through the <a href="/confluence/display/CAMEL/JSON"
title="JSON">JSON</a> Dataformat there's now a <tt>jsonView</tt> attribute
you could make use of directly inside the <a href="/confluence/display/CAMEL/DSL" title="DSL">DSL</a>
	<li><a href="/confluence/display/CAMEL/SMPP" title="SMPP">SMPP</a> now
supports optional parameters in all commands where they are possible.</li>
	<li><a href="/confluence/display/CAMEL/JDBC" title="JDBC">JDBC</a> now
supports named parameters.</li>
	<li>Added timeout support for <a href="/confluence/display/CAMEL/Direct" title="Direct">Direct</a>
producers to wait for consumer to become active.</li>
	<li>Added <tt>stats</tt> action to <a href="/confluence/display/CAMEL/ControlBus"
title="ControlBus">ControlBus</a> to easily get performance statics in a single XML
	<li>Added support for request timeout on <a href="/confluence/display/CAMEL/Netty"
title="Netty">Netty</a> producer, and to configure logging level on <a href="/confluence/display/CAMEL/Netty"
title="Netty">Netty</a> consumer to be less noisy for ChannelClosedException which
can flood the logs when client disconnects abruptly.</li>
	<li><a href="/confluence/display/CAMEL/SpringBatch" title="SpringBatch">Spring
Batch</a> component producer now returns the <tt>JobExecution</tt> instance
as the output message. Users can use the <tt>JobExecution</tt> instance to perform
some operations using the Spring Batch API directly.</li>
	<li>Added support for NULL values in <a href="/confluence/display/CAMEL/SQL+Component"
title="SQL Component">SQL</a> with named parameters.</li>
	<li>Optimized <a href="/confluence/display/CAMEL/Jetty" title="Jetty">Jetty</a>
streaming responses in non-chunked mode; and as well using buffer sizes based on <tt>HttpServletResponse.getBufferSize()</tt>
instead of fixed size of 4kb.</li>
	<li>Added <tt>greedy</tt> option to <a href="/confluence/display/CAMEL/Polling+Consumer"
title="Polling Consumer">scheduled polling consumer</a>.</li>

	<li>Fixed setting .id in Java DSL on some <a href="/confluence/display/CAMEL/EIP"
title="EIP">EIP</a>s such as the <a href="/confluence/display/CAMEL/Validate"
	<li>Fixed <a href="/confluence/display/CAMEL/Dead+Letter+Channel" title="Dead Letter
Channel">Dead Letter Channel</a> always handled exception, which wasn't the case

Clause</a> was in use, which didn't had handled=true.</li>
	<li>Fixed <a href="/confluence/display/CAMEL/Using+PropertyPlaceholder" title="Using
PropertyPlaceholder">Using PropertyPlaceholder</a> in attributes defined on <tt>&lt;camelContext&gt;</tt>.</li>
	<li>All Camel <a href="/confluence/display/CAMEL/Components" title="Components">Components</a>

	<li>Fixed a race condition in <a href="/confluence/display/CAMEL/File2" title="File2">File</a>

	<li><a href="/confluence/display/CAMEL/HTTP4" title="HTTP4">HTTP4</a> now
validates that only one instance of <tt>org.apache.camel.util.jsse.SSLContextParameters</tt>
