<h2><a name="Camel2.8.0Release-NewandNoteworthy"></a>New and Noteworthy</h2>

<p>Welcome to the 2.8.0 release which approx XXX issues resolved (new features, improvements
and bug fixes such as...)</p>

	<li>Fixed the OGNL support of <a href="/confluence/display/CAMEL/Simple" title="Simple">Simple</a>
language to support dots in key for map access.</li>
	<li>You can now specify <a href="/confluence/display/CAMEL/Bean+Binding" title="Bean
Binding">type parameters</a> in <a href="/confluence/display/CAMEL/Bean" title="Bean">Bean</a>
to exact select method to be used when having overloaded methods (overloaded methods have
same name, but vary in parameter types).</li>
	<li>The <a href="/confluence/display/CAMEL/FTP" title="FTP">SFTP</a> component
now allows you to customize keep alive settings.</li>
	<li>Fixed issue if explict setting <tt>JmsMessage</tt> body to <tt>null</tt>
would cause Camel to re-initialize the body from the underlying <tt>javax.jms.Message</tt>
on access again.</li>
	<li><a href="/confluence/display/CAMEL/Mock" title="Mock">Mock</a> endpoints
is now lenient, which means its easier to replace components with <a href="/confluence/display/CAMEL/Mock"
title="Mock">Mock</a> for testing purposes. Using uri parameters which the <a
href="/confluence/display/CAMEL/Mock" title="Mock">Mock</a> endpoint wont no longer
complain about being unknown parameters.</li>
	<li>Camel places a breadcrumb header in the Camel <a href="/confluence/display/CAMEL/Message"
title="Message">Message</a> which allow us to keep track of messages across transports
such as <a href="/confluence/display/CAMEL/JMS" title="JMS">JMS</a>, <a href="/confluence/display/CAMEL/HTTP"
title="HTTP">HTTP</a> and many others. See more details at <a href="/confluence/display/CAMEL/MDC+logging"
title="MDC logging">MDC logging</a>.</li>
	<li>Improved <a href="/confluence/display/CAMEL/XPath" title="XPath">XPath</a>

title="How do I configure the maximum endpoint cache size for CamelContext">endpoint cache</a>
can be configured on <a href="/confluence/display/CAMEL/CamelContext" title="CamelContext">CamelContext</a>.</li>
	<li><a href="/confluence/display/CAMEL/Cometd" title="Cometd">Cometd</a>
supports custom security policy and extensions as <a href=""
class="external-link" rel="nofollow">documented here</a></li>

	<li>Added stats for number of redeliveries and handled failures to JMX.</li>
	<li>Added support for <a href="/confluence/display/CAMEL/camel-jboss" title="camel-jboss">JBoss
	<li><a href="/confluence/display/CAMEL/JMS" title="JMS">JMS</a> consumer
uses <tt>CACHE_AUTO</tt> for default cache level. This ensure that it will automatic
detect if its transacted and use <tt>CACHE_NONE</tt> which must be used for transacted.
And <tt>CACHE_CONSUMER</tt> for non transacted.</li>
	<li>Improved <a href="/confluence/display/CAMEL/Splitter" title="Splitter">Splitter</a>
in parallel mode to be more responsive when aggregating on-the-fly under high load, and reducing
number of threads in-use.</li>

title="Wire Tap">Wire Tap</a> to execute custom logic when preparing messages. For
example you can use that to deep clone message bodies, or enrich messages before they are
	<li>Added <tt>CamelSqlQuery</tt> header to <a href="/confluence/display/CAMEL/SQL+Component"
title="SQL Component">SQL Component</a> to specify (per exchange) SQL query.</li>

supports replicating cache across nodes using listeners.</li>
	<li><a href="/confluence/display/CAMEL/Cache" title="Cache">Cache</a> headers

being redeployed (hot-deploy) in Apache ServiceMix may fail.</li>
	<li><a href="/confluence/display/CAMEL/CXF" title="CXF">CXF</a> uses case-insensitive
keys for CXF protocol headers, which Apache CXF itself also uses.</li>
	<li>Fixed issue with stopping context scoped <a href="/confluence/display/CAMEL/Error+Handler"
title="Error Handler">Error Handler</a> if a route was stopped, for example using
<a href="/confluence/display/CAMEL/Camel+JMX" title="Camel JMX">JMX</a>.</li>
	<li>Updated documentation of each <a href="/confluence/display/CAMEL/EIP" title="EIP">EIP</a>

EIP will now by default uses eager completion check when grouped exchange has been enabled.</li>
	<li>Internal Camel caches now uses a <a href=""
class="external-link" rel="nofollow">SoftReference</a> which allows the JVM to be
able to garbage collection from the cache in case its running out of memory. This should help
Camel end users when running in low memory systems.</li>
	<li>Added 2 new <a href="/confluence/display/CAMEL/Camel+Maven+Archetypes" title="Camel
Maven Archetypes">Camel Maven Archetypes</a> for OSGi using spring-dm or blueprint</li>
	<li>The <a href="/confluence/display/CAMEL/Log" title="Log">Log</a> component
will now by default <b>not</b> show stream message bodies. Use the new <tt>showStreams</tt>
option to enable that explicit.</li>
	<li>Improved startup time of Camel by hard loading type converters from <tt>camel-core</tt>
	<li>Made unit testing the Camel <a href="/confluence/display/CAMEL/Source" title="Source">Source</a>
go faster</li>
	<li>The Camel <a href="/confluence/display/CAMEL/Testing" title="Testing">test
kit</a> will now by default lazy load type converters which makes unit testing faster
for most tests.</li>
	<li>Added new features to <a href="/confluence/display/CAMEL/AdviceWith" title="AdviceWith">AdviceWith</a>
to support <tt>weaveByType</tt>, selectors, and a shorthand to easily add nodes
to start/end of routes.</li>
	<li><a href="/confluence/display/CAMEL/Camel+Test" title="Camel Test">Camel Test</a>
support setting up <a href="/confluence/display/CAMEL/CamelContext" title="CamelContext">CamelContext</a>
once per test class, instead of every test method. This can speedup testing when having multiple
test methods in the same unit test class.</li>
	<li>Fixed an issue with <a href="/confluence/display/CAMEL/FTP2" title="FTP2">FTP</a>
producer not trying to re-connect if pre write check fails. By re-connecting the producer
can recover and process the message without failing.</li>
	<li><a href="/confluence/display/CAMEL/Camel+JMX" title="Camel JMX">Camel JMX</a>
can now show the routes as XML on the CamelContext/Route mbeans. Likewise route(s) can be
updated/added from XML as well.</li>
	<li><a href="/confluence/display/CAMEL/Camel+JMX" title="Camel JMX">Camel JMX</a>
added operations to <tt>ManagedCamelContext</tt> to send messages which has headers
as well.</li>
	<li><a href="/confluence/display/CAMEL/Camel+JMX" title="Camel JMX">Camel JMX</a>
added operations to <tt>BrowsableEndpoint</tt> mbeans to show message in generic
XML format.</li>
	<li>The JDBC and JPA based idempotent repositories now contains a createdAt property/column.</li>
	<li>Improved the <a href="/confluence/display/CAMEL/AWS-SQS" title="AWS-SQS">AWS&#45;SQS</a>
component to change all queue attributes (VisibilityTimeout, MaximumMessageSize, MessageRetentionPeriod
and Policy) at a later time if needed.</li>
	<li>Aligned the authentication and proxy parameter names so <a href="/confluence/display/CAMEL/HTTP4"
title="HTTP4">HTTP4</a> uses same names as <a href="/confluence/display/CAMEL/HTTP"
title="HTTP">HTTP</a> component.</li>
	<li>Removed some very seldom used expression builders in Java DSL that caused a minor
problem with being able to render the routes as XML. By removing those we ensure the routes
creating using Java DSL can accurately render itself as XML DSL routes.</li>
	<li>Added <a href="/confluence/display/CAMEL/Hazelcast+Component" title="Hazelcast
Component">Hazelcast</a> as supported store for the <a href="/confluence/display/CAMEL/Idempotent+Consumer"
title="Idempotent Consumer">Idempotent Consumer</a> EIP</li>
	<li><a href="/confluence/display/CAMEL/Tracer" title="Tracer">Tracer</a>
uses same logic as <a href="/confluence/display/CAMEL/Log" title="Log">Log</a>
component for extracting message body. By default they will not log/trace message bodies from
stream/files. But instead indicate its a stream/file message body. You can control this behavior
by setting a property on the <a href="/confluence/display/CAMEL/CamelContext" title="CamelContext">CamelContext</a>.</li>
	<li>Added monitor type consumer to <a href="/confluence/display/CAMEL/JMX" title="JMX">JMX</a>
consumer. This new style of consumer automatically creates and deploys a monitor bean (counter,
gauge, or string) to monitor the specified attribute of an existing bean. This is useful for
cases where a route wants to monitor a bean without relying on an pre-existing deployment
and configuration of a monitor.</li>
	<li>Added <a href="/confluence/display/CAMEL/Ref+Language" title="Ref Language">Ref
Language</a> to make it easy to refer and use custom <a href="/confluence/display/CAMEL/Expression"
title="Expression">Expression</a> in XML DSLs.</li>
	<li>You can provide additional arguments to <a href="/confluence/display/CAMEL/Scripting+Languages"
title="Scripting Languages">Scripting Languages</a> as a header on the Camel Message.</li>
	<li>Added support for setting custom properties in the endpoint uri for <a href="/confluence/display/CAMEL/CXF"
title="CXF">CXF</a> by using <tt>properties.</tt> as prefix, eg <tt>properties.mtom-enabled=true</tt>
to enable MTOM. This is usable if you configure and use <a href="/confluence/display/CAMEL/CXF"
title="CXF">CXF</a> from Java DSL. The XML DSL has a specialized CXF schema to configure
this using XML tags.</li>
	<li>Added option <tt>disableTimeToLive</tt> on <a href="/confluence/display/CAMEL/JMS"
title="JMS">JMS</a> to force disabling time to live value. Added more details in
<a href="/confluence/display/CAMEL/JMS" title="JMS">JMS</a> documentation about
the need for synchronizing clocks for <a href="/confluence/display/CAMEL/JMS" title="JMS">JMS</a>
systems when doing request/reply, and why the option <tt>disableTimeToLive</tt>
may come handy.</li>
	<li><a href="/confluence/display/CAMEL/Spring+Web+Services" title="Spring Web Services">Spring-WS</a>
producer now propagates headers correctly.</li>
	<li>Components loading resources such as <a href="/confluence/display/CAMEL/Velocity"
title="Velocity">Velocity</a>, <a href="/confluence/display/CAMEL/XSLT" title="XSLT">XSLT</a>,
<a href="/confluence/display/CAMEL/XQuery" title="XQuery">XQuery</a>, <a href="/confluence/display/CAMEL/FreeMarker"
title="FreeMarker">FreeMarker</a> etc. now leverages Camels <a href="/confluence/display/CAMEL/Pluggable+Class+Resolvers"
title="Pluggable Class Resolvers">Pluggable Class Resolvers</a> which ensures they
now work in <a href="/confluence/display/CAMEL/Using+OSGi+blueprint+with+Camel" title="Using
OSGi blueprint with Camel">OSGi Blueprint</a>.</li>
	<li><tt>DefaultPackageScanClassResolver</tt> uses a JAR cache to speedup
scanning JARs. This ensures Camel bootup faster, in case it re-scan JARs from the cache.</li>
	<li>Exposed Restlet API in <a href="/confluence/display/CAMEL/Restlet" title="Restlet">Restlet</a>
to allow end users to be in full control. For example using the <tt>org.restlet.Response</tt>
instance to populate the response from a <a href="/confluence/display/CAMEL/Restlet" title="Restlet">Restlet</a>
	<li>Splited camel transport for cxf out of camel-cxf module. If you want to use camel
transport for cxf or the cxfbean component, you need to add the dependency of camel-cxf-transport.</li>
	<li><a href="/confluence/display/CAMEL/Aggregator2" title="Aggregator2">Aggregate</a>
EIP will restore timeout values from existing exchanges from aggregation repository upon start.
This ensures that restarting Camel, will allow the aggregator trigger timeouts for those existing
	<li><a href="/confluence/display/CAMEL/Bean" title="Bean">Bean</a> component:
<a href="/confluence/display/CAMEL/Parameter+Binding+Annotations" title="Parameter Binding
Annotations">Parameter Binding Annotations</a> are now also inherited from superclasses
and interfaces.</li>

	<li>Not all <a href="/confluence/display/CAMEL/Examples" title="Examples">Examples</a>
have ANT build.xml files to run the example using ANT.</li>
	<li>The project cannot fully build the site using Maven (eg running <tt>"mvn
site"</tt>. There is no plan to make this work as the project do not use the maven site.</li>
	<li>The <tt>camel-spring-ws</tt> feature does not work in Apache ServiceMix
or Apache Karaf.</li>

<h2><a name="Camel2.8.0Release-Importantchangestoconsiderwhenupgrading"></a>Important
changes to consider when upgrading</h2>

	<li>Upgraded to slf4j 1.6.1</li>
	<li>Upgraded to Apache CXF 2.4.0 (CXF 2.3.x or older is no longer supported)</li>
	<li>The <tt>testConnectionOnStartup</tt> option on <a href="/confluence/display/CAMEL/JMS"
title="JMS">JMS</a> now also checks JMS producers as well.</li>
	<li>Fixed <tt>InterceptStrategy</tt> to pass in actual <tt>OutputDefinition</tt>.
For example in a route with a <a href="/confluence/display/CAMEL/Splitter" title="Splitter">Splitter</a>,
it would now pass in the children of the splitter, in the <tt>wrapProcessorInInterceptors</tt>
	<li>The <a href="/confluence/display/CAMEL/Log" title="Log">Log</a> component
will now by default <b>not</b> show stream message bodies. Use the new <tt>showStreams</tt>
option to enable that explicit. Likewise the <a href="/confluence/display/CAMEL/Log" title="Log">Log</a>
component will <b>not</b> automatic convert the payload to <tt>StreamCache</tt>.
For that you need to explicit enable <a href="/confluence/display/CAMEL/Stream+caching"
title="Stream caching">Stream caching</a> on the route or CamelContext.</li>
	<li>Removed the artifacts <tt>camel-spring-tests.jar</tt> and <tt>camel-blueprint-tests.jars</tt>
from being released to <a href="" class="external-link" rel="nofollow">Maven
Central Repository</a>.</li>
	<li>Upgraded to use Commons Net 2.2 (was 2.0) in <a href="/confluence/display/CAMEL/FTP2"
title="FTP2">FTP</a> component.</li>
	<li>Splited camel transport for cxf out of camel-cxf module. If you want to use camel
transport for cxf or the cxfbean component, you need to add the dependency of camel-cxf-transport.</li>
