New and Noteworthy

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

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 allocated objects to reduce overhead on GC etc, and much more.
The Camel Maven Plugin can now validate for duplicate route ids in your source code.
Splitted Twitter component into 4, now directmessage, seach, streaming and timeline has its own endpoint and scheme. See documentation for more details
Introduced HeadersMapFactory SPI which allows to plugin different implementations, or to use case sensitive maps that are faster than the default.
Allow Kafka consumer to break on first unhandled exception, sync the offset from last known good, and then re-connect after one timeout cycle, to restart consuming again. This avoids loosing the failed message, but retry it again on either this consumer, or another consume which was re-balanced by Kafka. This requires to be turned on with the new option breakOnFirstError which can be set on both component or endpoint level.
Starting and stoping the CamelContext when used with Spring framework (SpringCamelContext) was revised to ensure that the Camel context is started last - when all resources should be available, and stopped first - while all resources are still available
Tracing via Tracer has been refactored to be using the Message History EIP which allows Camel to use same logic instead of doing twice the tracing/capture during runtime. This reduced the memory footprint.

Fixed these issues

Fixed a infinitive recursion in Camel's Error Handler when an onException was routing to another route using direct endpoint and this route would throw a new exception that would circle back to the same onException or at a later point, which will cause an endless recursion.
Fixed a potential issue with masking password from URI using RAW(xxx) would reveal part of the password if the password contains a & character.
The Restlet component is now internally using curly brackets f or its uri patterns instead of regular parentheses so it works similar to the other REST component and as Restlet framework itself does
Fixed Hystrix EIP having wrong default for circuitBreakerForceClose when using camel-hystrix-starter with Spring Boot. The default should be false and not true
Fixed Hystrix EIP when failing and running fallback not signaling to Hystrix itself so it can keep state of the failure and react accordingly to run in half-open mode as well.
Fixed MDC logging loosing route id after calling a direct route from within a transacted route
Fixed a regression with Bean and Simple OGNL expressions causing ambiguous method call exception when calling method implemented by super class when method is defined by interface and abstract class
Fixed Rest DSL (server side) not returning response on all valid uri paths when clients call using a HTTP OPTIONS request
Fixed Rest producer not using HTTP method (verb such as PUT) from the endpoint uri when calling a remote REST service
Fixed Timer routes to shutdown more graceful and allow pending tasks to complete while they are in-flight.

New Enterprise Integration Patterns

New Components

camel-headersmap - a faster implementation of case-insenstive map (used by camel message headers) which can be added to classpath at runtime to be auto ins talled
camel-reactor - a reactor based back-end for camel's reactive streams component

Important changes to consider when upgrading

Maven 3.3.3 or newer is required to build the project
camel-infinispan - the result is not more set in the CamelInfinispanOperationResult header but in the in body. To change this behavior you can set the header CamelInfinispanOperationResultHeader with the name of the header that should contains the result or with the resultHeader uri option
camel-infinispan - the uri option command has been deprecated and replaced by operation for consistency
camel-infinispan - the commands are now int the short form PUT, GET etc. old operation names like CamelInfinispanOperationPut, CamelInfinispanOperationGet etc have been deprecated.
camel-undertow - matchOnUriPrefix option is defaulted to be FALSE in order to make it consistent with other components like Camel HTTP components.
Splitted Twitter component into 4, now directmessage, seach, streaming and timeline has its own endpoint and scheme. See documentation for more details
RuntimeEndpointRegistry is no longer in extended mode by default. To use that you need to set management statistics level to Extended explicit.
