+
+Welcome to the 2.19.0 release which resolved over 670 issues including
+new features, improvements and bug fixes.
+
+* Introduced
+Camel Connector's which is a simplified version of a Camel component that has
+been pre-configured for a specific use-case.
+* Upgraded to Spring Boot 1.5.x.
+* The Camel Maven Plugin now provides the
+`camel:validate` goal to parse your Java and XML source code for any
+Camel routes and report invalid Camel endpoint uri and simple expression
+errors. You can run this at code time (not runtime).
+* Camel `Main` and Spring Boot
+and Camel Maven Plugin can now auto
+terminate the JVM after Camel has been running for maximum duration of
+seconds, processed messages or been idle for a period.
+* Camel source code can build with Java 9 in preparation for official
+support for Java 9 in a future release
+* 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
+* Deprecated more components and camel-core APIs that will be dropped in
+Camel 3.0 or sometime in the future
+* Introduced `ReloadStrategy` as SPI which allows custom providers to
+implement logic for triggering live reloads of Camel routes.
+* The Camel Maven Plugin now allows to
+live reload route changes from XML files when running Camel. This can
+also be enabled from the `Main` class.
+* Introduced a new `camel-catalog-rest` artifact which is a tiny
+standalone REST API of the CamelCatalog using JAX-RS and Swagger
+Annotations.
+* Added `camel-catalog-rest-app` as a standalone application which used
+Apache CXF with Jetty to host the Catalog REST API with embedded Swagger
+UI
+* Returning `null` from Bean should work similar to
+how `setBody` and `transform` works when they set a `null` body.
+* The Camel Spring Boot starter components now have their auto
+configuration depends
+on `org.apache.camel.springboot.CamelAutoConfiguration` which makes it
+easier writing unit tests where you can
+exclude `org.apache.camel.springboot.CamelAutoConfiguration` to turn off
+Camel Spring Boot auto configuration completely.
+* Camel now supports OWASP dependency check maven plugin
+* NATS component now supports TLS and explicit flushing
+(with timeout) of the connection
+* Metrics component
+now supports Gauge type
+* File consumer now supports idempotent-changed and
+idempotent-rename read lock strategies for clustering.
+* Camel Catalog now supports custom runtime providers that only includes
+the supported Camel components, languages and data formats running in
+that container. For example for Karaf or Spring Boot in the
+camel-catalog-provider-karaf and camel-catalog-provider-springboot.
+* The bean
+component will when calling a method that returned an instance of
+`Callable` now call that callable to obtain the chained result. This
+allows to call Groovy functions/closures etc.
+* Failover Load Balancer with
+inheritErrorHandler=false, now allows
+Error Handler to react after the load
+balancer is exhausted.
+* Salesforce component now supports limits, recent
+items, approvals and composite API
+* Dumping Camel routes as XML now includes custom namespaces which are
+at xpath expressions etc. Likewise updating Camel routes from XML can
+now include namespaces which will be associated on xpath expressions.
+* Added `RouteIdFactory` which can auto assign route ids based on the
+consumer endpoints to use more sensitible names, instead of route1,
+route2, etc.
+* Add `skip` function to Simple language
+* Upgraded to Jetty 9.3 (Jetty 9.2 still supported for Karaf 4.0.x
+users)
+* `RouteBuilder` auto-configuration can now be disabled
+from Camel CDI configuration
+* Camel contexts automatic start can now be disabled
+from Camel CDI configuration
+* Camel CDI now provides support
+for `TransactionErrorHandler` and `TransactionPolicy` via JTA
+* Asynchronous support for CXF JAX-RS producers has
+been added
+* The JSonPath language now supports Map and List
+types and POJOs as well. For POJOs you need to have Jackson on the
+classpath.
+* Data Format which marshal to JSon or XML now
+set the content-type header to application/json or application/xml
+appropriately.
+* The Kafka component can now store offset state
+offline (stateRepository) to preserve this information and be able to
+resume from previous offset.
+* The Kafka component has been improved to be easier to
+configure and use. Notice there is a backwards incompatible change so
+users need to migrate.
+* A topic based idempotent repository that
+is Kafka based for
+the Idempotent Consumer EIP
+* The Kafka component will automatic type convert the
+message body to the type specified by the configured serializer (is
+string by default) when sending to kafka. You can also now configure key
+and partitionKey in the endpoint uri, instead of having to specify as
+headers.
+* The Kafka consumer will now auto commit on stop to
+ensure the broker has the latest offset commit. The
+option `autoCommitOnStop` can be configured to be sync,async or none.
+* Added easy predicate parser to JSonPath to more
+easily define simple predicates without using the more complex jsonpath
+notation with all the symbols
+* The Box component has been migrated to use the Box v2
+Java API as the old v1 API is going to be shutdown from summer 2017
+* Examples overview now generate from the source code to ensure its up
+to date
+* Added declarative Transformer
+and Validator
+which performs transformation/validation according to the data type
+information declared on a route by
+inputType and/or outputType.
+There're a few examples demonstrates this feature:
+camel-example-transformer-blueprint, camel-example-transformer-cdi,
camel-example-transformer-demo,
+and camel-example-validator-spring-boot
+* Added query support for JPA Producer
+
+The following issues have been fixed
+
+* Fixed starting Camel on Oracle JDK 1.8.0_19 or lower, which would
+throw an UnsupportedOperationException
+* Fixed running `mvn camel:run` when using OSGi Blueprint
+* Fixed Hystrix EIP to also execute fallback if
+execution was rejected or short-circuited or other reasons from
+Hystrix.
+* Fixed Hystrix EIP race condition when timeout
+was hit and fallback is executed could let to Camel Exchange having
+wrong caused exception.
+* Fixed adding new routes to running CamelContext and if the new routes
+would fail to startup, then before these routes would "hang around". Now
+only succesful started routes are added.
+* Adding or removing routes that starts
+from Undertow no longer restart the entire HTTP
+server
+* VM endpoint should prepare exchange with the
+CamelContext from the consumer and not from cached endpoint which can be
+different
+* Fixed a bug when using Rest DSL
+with SERVLET could cause a java.io.IOException:
+Stream closed exception when using Bean component in the route.
+* Fixed an issue when using `pipeline` in Java DSL not setting up the
+EIP correctly which could lead to runtime route not as intended.
+* Fixed Dropbox to
+use Stream caching to avoid reading entire
+file into memory so Camel can process big files
+* Fixed `toD` issue with splitting uris when RAW values had + sign
+* Fixed adviceWith may behave differently when using multiple advices in
+the same order and you would advice on the same nodes.
+* Fixed camel-zipkin to be able to startup and
+work with Camel XML
+* Fixed FTP2 readLock=changed not working (when
+fastFileExists=false) if no sub folder was specified as starting
+directory.
+* Fixed Simple language when using indexing with a
+nested function
+* Fixed issue with `@Consume` not having `CamelContext` injected and its
+lifecycle managed by `CamelContext`
+* Fixed Netty double buffer release leak in Netty4
+and Netty4 HTTP
+
+API breaking
+
+* The groovy DSL from camel-groovy has been moved into its own
+camel-groovy-dsl module. The camel-groovy now only contains the Camel
+Language
+* Camel-spring-LDAP now uses java.util.function.BiFunction<L, Q, S>
+instead
+of org.apache.camel.component.springldap.LdapOperationsFunction<Q, S>
+* The deprecated APIs from camel-spring-boot has been removed as part of
+upgrading and supporting Spring Boot 1.5.x
+* The `getComponentDocumentation` method on `CamelContext` 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.
+* camel-mongodb-gridf schema has been renamed
+from *gridfs* to *mongodb-gridfs* to avoid confusion.
+* The commands-core has the Catalog commands removed
+* The org.apache.camel.spring.boot.FatJarRouter has been removed, just
+use regular `RouteBuilder` classes in Spring Boot applications.
+* The Kafka endpoint option
+`seekToBeginning=true` should be migrated to `seekTo=beginning`
+* The Kafka endpoint option bridgeEndpoint has moved from endpoint to
+the KafkaConfiguration class so all options are together.
+* The Kafka 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
+`kafka:myserver?topic=sometopic` is
+now `kafka:sometopic?brokers=myserver`
+* The Infinispan uri syntax has changed from
+infinispan:hostName?options to infinispan:cacheName?options
+
+Important changes to consider when upgrading
+
+* 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.
+* Groovy DSL and Scala DSL is deprecated and planned to be moved to
+Camel Extra and not distributed out of
+the box in the future.
+* Camel now uses Karaf 4.x API and therefore not possible to run on
+older Karaf versions.
+* `camel-blueprint` changed startup behavior to start on
+Blueprint.CREATED event which would be more `correct` way of startup
+instead of Blueprint.REGISTERED as before.
+* 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.
+* camel-spring-javaconfig removed from Karaf features as it was not
+really supported in OSGi/Karaf.
+* camel spring-boot shell commands have been removed as spring-boot
+shell has been deprecated in spring-boot.
+* camel-mongodb-gridf schema has been renamed from gridfs to
+mongodb-gridfs to avoid confusion.
+* 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
+* The JSon schema from camel-catalog have changed to use boolean,
+integer and numeric values when applicable instead of using string
+values for everything.
+* The camel-catalog Karaf commands has been removed
+
