Camel 2.7.0 release (currently in progress)

New and Noteworthy

Welcome to the 2.7.0 release which approx XXX issues resolved (new features, improvements and bug fixes such as...)

• Switched to use slf4j as the logger instead of commons logging.
• Camel now checks state of Service during starting/stopping the Lifecycle of the Service. This avoids double starting/stopping in case the service was already in the desired state.
• Added support for MDC logging with Camel
• JMS consumer now eager checks if Camel is shutting down and signals that to its DefaultMessageListenerContainer which avoids trying to re-connect/failover during shutdown.
• Introduced option to automatic Mock endpoints during testing. This makes testing without having to add Mock endpoints in your routes a breeze. See more details at Mock component documentation.
• Added assertPeriod option to Mock endpoint, which is a period im milliseconds, that the Mock will pause and then re-assert itself to ensure the assertion is still valid. This can be used as a threshold when testing with expectations that exactly a given number of messages should arrive on the Mock endpoint.
• Added arrives DSL to Mock endpoint to allow you to setup expectations about timespan between messages arriving on the Mock endpoint. See more details at Mock component documentation.
• HTTP4 is upgraded to use Apache HttpClient 4.1
• Fixed an issue with File consumer having absolute starting directory and using absolute paths in the move option as well
• Fixed concurrent append to the same file in the File producer
• Fixed issue with restarting Quartz causing a failure due trigger name already exists issue for stateful jobs.
• Its now possible to use multiple QuartzScheduler's when deploying multiple Camel applications in the same JVM classloader.
• Quartz update checker is now always disabled, see more details here
• Fixed potential issue installing camel-ftp feature in Apache ServiceMix

API breaking

• FATAL has been removed from org.apache.camel.LoggingLevel. Use ERROR instead.
• org.apache.camel.processor.Logger has been renamed to org.apache.camel.processor.CamelLogger, and it now uses slf4j as the logger.

Known Issues

• The Tracer may not output all details for some situations such as when using onCompletion or intercept etc.
• Not all Examples have ANT build.xml files to run the example using ANT.
• Project cannot be fully build using Maven 3.0
• camel-script which uses ScriptEngineManager from the JDK, cannot load script engines from packages outside the JDK.
• Stopping a route after using adviceWith maybe cause issues with error handlers, see CAMEL-3534

Important changes to consider when upgrading

• Java 1.6 or better is required
• Spring 3.0.x or better is required, when using Spring
• Apache CXF 2.3.2 or better is required, when using CXF
• Switched to use slf4j as the logger instead of commons logging. That means you may have to included slf4j-log4j12 as dependency if you are using log4j.
  See documentation at slf4j for more details.
• If you have developed custom Camel Components and your Endpoint class extends DefaultEndpoint then its advised to use the doStart and doStop instead of start and stop.
• camel-cxf endpoint will copy the attachments between the camel message and cxf message when it works in POJO data format, please access the attachment objects from the camel message body.
