build with Java 9 in preparation for official support for Java 9 in a future
release</li><li>All the Camel Spring Boot starter components now has more of
the components default values included in their metadata which allows tooling
to display such information</li><li>Deprecated more components and camel-core
APIs that will be dropped in Camel 3.0 or sometime in the
future</li><li>Introduced <code>ReloadStrategy</code> as SPI which
allows custom providers to implement logic for triggering live reloads of Camel
routes.</li><li>The  <a shape="rect"
href="camel-maven-plugin.html">Camel Maven Plugin</a> now allows to live
reload route changes from XML files when running Camel. This can also be

how <code>setBody</code> and <code>transform</code> works
when they set a <code>null</code> body.</li><li>The Camel Spring Boot
starter components now have their auto configuration depends
on <code>org.apache.camel.springboot.CamelAutoConfiguration</code> which
makes it easier writing unit tests where you can
exclude <code>org.apache.camel.springboot.CamelAutoConfiguration</code> to
turn off Camel Spring Boot auto configuration completely.</li><li>Camel now

camel-catalog-provider-springboot.</li><li>The <a shape="rect"
href="https://cwiki.apache.org/confluence/display/WW/bean";>bean</a> component
will when calling a method that returned an instance of
<code>Callable</code> now call that callable to obtain the chained result.
This allows to
call Groovy functions/closures etc.</li><li>Failover <a shape="rect"
href="load-balancer.html">Load Balancer</a> with inheritErrorHandler=false, now
allows Camel's <a shape="rect" href="error-handler.html">Error Handler</a>

associated on xpath expressions.</li><li>Added <code>RouteIdFactory</code>
which can auto assign route ids based on the consumer endpoints to use more
sensitible names, instead of route1, route2,
etc.</li><li>Add <code>skip</code> function to <a shape="rect"

part of upgrading and supporting Spring Boot
1.5.x</li><li>The <code>getComponentDocumentation</code> method
on <code>CamelContext</code> is deprecated and returns null. The embedded
HTML documentation in all the Camel components has been removed as they are not
in use/maintained, and the JSon schema is the actual information. Use the
camel-catalog for component documentation where you can get all the
documentation in both ascii doc and html format.</li><li>camel-mongodb-gridf

href="kafka.html">Kafka</a> component has been improved to be easier to
configure and use. Notice there is a backwards incompatible change so users
need to migrate. The kafka uri is changed from kafka:brokers to kafka:topic. So
you need to specify the topic name in the context-path and the brokers as
parameters, eg before <code>kafka:myserver?topic=sometopic</code> is
now <code>kafka:sometopic?brokers=myserver</code></li><li><span

id="Camel2.19.0Release-KnownIssues">Known Issues</h2><h2
id="Camel2.19.0Release-Importantchangestoconsiderwhenupgrading">Important
changes to consider when upgrading</h2><ul><li>camel-spring-dm has been
disabled from the karaf features file so users cannot install it out of the box
as it does not work properly. camel-spring-dm has been deprecated for a long
time and users are encouraged to use osgi blueprint instead. The JAR is still
shipped and can be installed manually but then you are on your own. The JAR
will be removed completed in a future release.</li><li>Groovy DSL and Scala DSL
is deprecated and planned to be moved to <a shape="rect" class="external-link"
href="https://camel-extra.github.io/"; rel="nofollow">Camel Extra</a> and not
distributed out of the box in the future.</li><li>Camel now uses Karaf 4.x API
and therefore not possible to run on older Karaf
versions.</li><li><code>camel-blueprint</c
ode> changed startup behavior to start on Blueprint.CREATED event which
would be more `correct` way of startup instead of Blueprint.REGISTERED as
before.</li><li>camel-spring-boot now don't include prototype scoped beans when
auto scanning for RouteBuilder instances, which is how camel-spring works. You
can turn this back using the includeNonSingletons
option.</li><li>camel-spring-javaconfig removed from Karaf features as it was
not really supported in OSGi/Karaf.</li><li>camel spring-boot shell commands
have been removed as spring-boot shell has been deprecated in
spring-boot.</li><li>camel-mongodb-gridf schema has been renamed from
<strong>gridfs</strong> to <strong>mongodb-gridfs</strong> to avoid
confusion.</li><li>camel-box has been migrated to use box v2 api so there may
be some migration needed as the old camel-box component was using box v1
api</li><li>The JSon schema from camel-catalog have changed to use boolean,
integer and numeric values when applicable in
stead of using string values for everything. </li><li>The camel-catalog
Karaf commands has been removed</li></ul><h2

changes to consider when upgrading</h2><ul><li>camel-spring-dm has been
disabled from the karaf features file so users cannot install it out of the box
as it does not work properly. camel-spring-dm has been deprecated for a long
time and users are encouraged to use osgi blueprint instead. The JAR is still
shipped and can be installed manually but then you are on your own. The JAR
will be removed completed in a future release.</li><li>Groovy DSL and Scala DSL
is deprecated and planned to be moved to <a shape="re

rel="nofollow">Camel Extra</a> and not distributed out of the box in the
future.</li><li>Camel now uses Karaf 4.x API and therefore not possible to run
on older Karaf versions.</li><li><code>camel-blueprint</code> changed
startup behavior to start on Blueprint.CREATED event which would be more
`correct` way of startup instead of Blueprint.REGISTERED as
before.</li><li>camel-spring-boot now don't include prototype scoped beans when
auto scanning for RouteBuilder instances, which is how camel-spring works. You
can turn this back using the includeNonSingletons
option.</li><li>camel-spring-javaconfig removed from Karaf features as it was
not really supported in OSGi/Karaf.</li><li>camel spring-boot shell commands
have been removed as spring-boot shell has been deprecated in
spring-boot.</li><li>camel-mongodb-gridf schema has been renamed from
<strong>gridfs</strong> to <strong>mongodb-gridfs</strong> to avoid
confusion.</li><li>camel-box has been migrated to use box v2 api so there may
be some migration needed as the old camel-box component was using box v1
api</li><li>The JSon schema from camel-catalog have changed to use boolean,
integer and numeric values when applicable instead of using string values for
everything. </li><li>The camel-catalog Karaf commands has been
