Java 9 as a technical preview. Official support for Java 9 will be forthcoming
in the following releases. (source code builds and tests on a Java 9
JVM). </li><li>Many internal optimisations in the Camel routing engine,
such as reducing thread contention when updating JMX statistics, reducing
internal state objects to claim less memory, and reducing the number of

having wrong default for circuitBreakerForceClose when using
camel-hystrix-starter with Spring Boot. The default should be false and not

longer in extended mode by default. To use that you need to set management
statistics level to Extended explicit.</li><li>There is no
RuntimeEndpointRegistry in use by default. You need to explicit configure a
registry to be used, or turn it on via management agent, or set the statics
level to extended mode.</li><li>Camel with Spring XML routes will no longer
register endpoints in the Spring registry from Camel routes where <from>
or <to> have endpoints assigned with an explicit id attribute. The
option registerEndpointIdsFromRoute can be set to true on
<camelContext> to be backwards compatible. However this registration is
deprecated, instead you should use <endpoint> to register Camel endpoints
with id's in Spring registry.</li><li>camel-spring-dm has been removed as it
was not working properly anyway and was deprecated some releases ago. For XML
DSL with OSGi use camel-blueprint instead.</li><li>Copying streams in IOHelper
from came-core now regard EOL of data if the first read byte is zero to work
around issues on some application servers like IBM WebSphere. This can be
turned off by setting JVM system property
"camel.zeroByteEOLEnabled=false".</li><li>The camel-jms component now dependes
by default on the JMS 2.0 API (geronimo-jms_2.0_spec) instead of JMS 1.1 API
(geronimo-jms_1.1_spec). However camel-jms works at runtime with both JMS 1.1
or 2.0 specs so include the JMS spec JARs of your choice.</li><li>camel-kura
upgraded to newer OSGi API version</li><li>camel-stomp uses the destination
as-is, where as before i
t would replace all slash characters with colon. But according to the STOMP
spec the destination should be used as-is, and is broker
specific.</li><li>camel-ignite is updated from using Ignite version 1.9.x to
2.2.x</li></ul><h2 id="Camel2.20.0Release-GettingtheDistributions">Getting the

longer in extended mode by default. To use that you need to set management

RuntimeEndpointRegistry in use by default. You need to explicit configure a
registry to be used, or turn it on via management agent, or set the statics
level to extended mode.</li><li>Camel with Spring XML routes will no long
er register endpoints in the Spring registry from Camel routes where
<from> or <to> have endpoints assigned with an explicit id
attribute. The option registerEndpointIdsFromRoute can be set to true on
<camelContext> to be backwards compatible. However this registration is
deprecated, instead you should use <endpoint> to register Camel endpoints
with id's in Spring registry.</li><li>camel-spring-dm has been removed as it
was not working properly anyway and was deprecated some releases ago. For XML
DSL with OSGi use camel-blueprint instead.</li><li>Copying streams in IOHelper
from came-core now regard EOL of data if the first read byte is zero to work
around issues on some application servers like IBM WebSphere. This can be
turned off by setting JVM system property
"camel.zeroByteEOLEnabled=false".</li><li>The camel-jms component now dependes
by default on the JMS 2.0 API (geronimo-jms_2.0_spec) instead of JMS 1.1 API
(geronimo-jms_1.1_spec). However camel
-jms works at runtime with both JMS 1.1 or 2.0 specs so include the JMS spec
JARs of your choice.</li><li>camel-kura upgraded to newer OSGi API
