of org.apache.camel.component.springldap.LdapOperationsFunction<Q,
S></li><li>The deprecated APIs from camel-spring-boot has been removed as
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

avoid confusion.</li><li>The <a shape="rect"

to <code>seekTo=beginning</code></li><li>The <
a shape="rect" 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></ul><h2
id="Camel2.19Release-KnownIssues">Known Issues</h2><h2
id="Camel2.19Release-Importantchangestoconsiderwhenupgrading">Important changes
to consider when upgrading</h2><ul><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</code> cha
nged 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 usin
g string values for everything. </li></ul><h2

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 inf
ormation. 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 schema has been renamed

need to migrate. The kafka uri is changed from kafka:brokers to kafka:topic. So

parameters, eg before <code>kafka:myserver?topic=sometopic</code> is

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</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 hav
e 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
