unsupported modules camel-web and camel-web-standalone.</li><li>Removed unsupported
camel:dot functionality from camel:run plugin.</li><li>Removed unsupported camel-archetype-scala-component

changed to be aligned like all the others having groupId as just org.apache.camel.</li><li>If
using MongoDB component, the option<em> invokeGetLastError</em> doesn't exist
anymore. The option invokeGetLastError instructs the MongoDB Java driver to invoke <em>getLastError()</em>
after every call. In the 3.0.0 MongoDB driver implementation, the <em>getLastError()</em>
method in WriteResult has been removed. So, if needed, use an acknowledged WriteConcern when
executing the write operation and then verify the correctness of the operation with 
 the method <em>wasAcknowledged()</em> of WriteResult.</li></ul><h2

and&#160;<a shape="rect" href="http4.html">HTTP4</a> is now easier as they
can be instantiated using a default no-arg constructor</li><li>Added&#160;<code>readLock=idempotent</code>
to the&#160;<a shape="rect" href="file2.html">File2</a> consumer which allows
to reuse an idempotent repository as read-lock which enables Camel to run reliable in clustered
mode, where each node competes for the same files from a shared file system. This requires
that the idempotent repository supports clustering such as&#160;<a shape="rect" href="hazelcast-component.html">Hazelcast
Component</a> or&#160;<a shape="rect" href="infinispan.html">Infinispan</a>
- or using the JDBC for a shared database table.</li></ul><p>Fixed the following
issues:</p><ul><li>File language now properly supports file extensions having
double dots, such as .tar.gz</li><li>Fixed issue with doTry not stopping routing
if a fault message was set using setFa
 ultBody within the doTry.</li><li>Fixed&#160;<a shape="rect" href="bean.html">Bean</a>&#160;language
to support end parenthesis in quoted string literals as part of method parameters, and not
as end of method signature.&#160;</li><li>Fixed&#160;<a shape="rect"
href="ftp2.html">FTP2</a> using&#160;<code>pollEnrich</code> with
disconnect=true and delete=true, would disconnect before deleting the file. Now we disconnect
last.</li><li>Various EIPs such as&#160;<a shape="rect" href="splitter.html">Splitter</a>,&#160;<a

href="multicast.html">Multicast</a> no longer reuse message id in their sub messages,
but each sub message has its own unique message id (just as the exchange has).</li><li>Fixed
an issue with the circuit breaker&#160;<a shape="rect" href="load-balancer.html">Load
Balancer</a> not honoring the half open after period after an error was detected.</li><li>Fixed&#160;<a
shape="rect" href="ftp2.htm

using method call expression in XML DSL was not working</li><li>Fixed stopping
a route may stop context scoped&#160;OnException that would otherwise send message to
an endpoint, now been stopped and an IllegalStateException was thrown while handling the exception.</li><li>Fixed
using a&#160;<a shape="rect" href="load-balancer.html">Load Balancer</a> from
a context scoped&#160;onException may double up its processors participating in the balancer

changes to consider when upgrading</h2><ul><li>The dumpRoutesAsXml operation
now preserve property placeholder used 
 in the route models.&#160;</li><li>Using setFaultBody / setFaultHeader behaves
similar to setBody / setHeader to preserve existing headers/attachments by setting on existing
IN or OUT message.</li><li>If using concurrent consumer on&#160;<a shape="rect"
href="jms.html">JMS</a>&#160;endpoints for request/reply over JMS then you must
use the new replyToConcurrentConsumers, replyToMaxConcurrentConsumers options to configure
the values.&#160;</li><li>When the&#160;<a shape="rect" href="aggregator2.html">Aggregator2</a>
is forced completed the exchange property&#160;<code>Exchange.AGGREGATED_COMPLETED_BY</code>
value has been changed from "forceCompletion" to "force" so its named like the other completion
triggers.</li><li>Removed unsupported modules camel-web and camel-web-standalone.</li><li>Removed
unsupported camel:dot functionality from camel:run plugin.</li><li>Removed unsupported
camel-archetype-scala-component from maven archetypes.</li><li>The Maven coordinate
for linkedin and o
 lingo2 components changed to be aligned like all the others having groupId as just org.apache.camel.</li><li>If
using MongoDB component, the option<em> invokeGetLastError</em> doesn't exist
anymore. The option invokeGetLastError instructs the MongoDB Java driver to invoke <em>getLastError()</em>
after every call. In the 3.0.0 MongoDB driver implementation, the <em>getLastError()</em>
method in WriteResult has been removed. So, if needed, use an acknowledged WriteConcern when
executing the write operation and then verify the correctness of the operation with the method
<em>wasAcknowledged()</em> of WriteResult.</li></ul><h2 id="Camel2.16.0Release-GettingtheDistributions">Getting
