<h2><a name="Camel2.3.0Release-NewandNoteworthy"></a>New and Noteworthy</h2>

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

<ul>
	<li><a href="/confluence/display/CAMEL/Using+PropertyPlaceholder" title="Using PropertyPlaceholder">Property
placeholders</a> in for example endpoint uris is not natively supported in <b>camel-core</b>
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.</li>
	<li><a href="/confluence/display/CAMEL/Using+PropertyPlaceholder" title="Using PropertyPlaceholder">Property
placeholders</a> also works in the &lt;CamelContext&gt; when using Spring XML.
Basically nearly all places where you enter text the property placeholder is supported.</li>
	<li>Added <tt>ExchangeSentEvent</tt> to <tt>EventNotifier</tt>
which contains time taken and is emitted when an <a href="/confluence/display/CAMEL/Exchange"
title="Exchange">Exchange</a> is sent to an <a href="/confluence/display/CAMEL/Endpoint"
title="Endpoint">Endpoint</a>. This allows end users to easily gather performance
stats for <a href="/confluence/display/CAMEL/Exchange" title="Exchange">Exchange</a>
send to endpoints.</li>
	<li>Added <tt>disconnect</tt> option to <a href="/confluence/display/CAMEL/MINA"
title="MINA">MINA</a> to close Mina session right after usage.</li>
	<li><a href="/confluence/display/CAMEL/Jetty" title="Jetty">Jetty</a> now
supports to get the <tt>HttpServletRequest</tt> and <tt>HttpServletResponse</tt>
from the <a href="/confluence/display/CAMEL/Message" title="Message">Message</a>
header.</li>
	<li><a href="/confluence/display/CAMEL/XPath" title="XPath">XPathBuilder</a>
now supports being used without an <a href="/confluence/display/CAMEL/Exchange" title="Exchange">Exchange</a>
which allows you to use it in a custom/generic fashion.</li>
	<li><a href="/confluence/display/CAMEL/XPath" title="XPath">XPath</a> now
supports using the JVM system property specifying a custom <tt>XPathFactory</tt>
to be used. You can use this to switch from default to use e.g. Saxon.</li>
	<li><a href="/confluence/display/CAMEL/XSLT" title="XSLT">XSLT</a> now
supports using <tt>&lt;xsl:include&gt;</tt> 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.</li>
	<li><a href="/confluence/display/CAMEL/Aggregator" title="Aggregator">Aggregator</a>
the <tt>completionPredicate</tt> is now being evaluated <em>on-the-fly</em>
which allows it to trigger before the <tt>batchTimeout</tt>.</li>
	<li><a href="/confluence/display/CAMEL/File2" title="File2">File</a>, <a
href="/confluence/display/CAMEL/FTP2" title="FTP2">FTP</a> added option <tt>eagerDeleteTargetFile</tt>
to control the behavior when using <tt>tempFile</tt> whether or not to eagerly
delete the target file or wait until last moment.</li>
	<li>Total overhaul of the <a href="/confluence/display/CAMEL/Aggregator2" title="Aggregator2">Aggregator</a>
EIP pattern.</li>
	<li>Reduced registering <a href="/confluence/pages/createpage.action?spaceKey=CAMEL&amp;title=Producer&amp;linkCreation=true&amp;fromPageId=13271482"
class="createlink">Producer</a>s 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.</li>
</ul>
