...

• Camel has upgraded from Spring Boot v1 to v2 and therefore v1 is no longer supported. Migrating from SB1 to SB2 may require changes, see the Spring Boot v1 to v2 migration documentation for details.
• Upgraded to Spring Framework v5 as default. Support for Spring Framework v4.3 is deprecated and not recommended to be used.
• Upgraded to Karaf 4.2. You may run Camel on Karaf 4.1 but we only officially support Karaf 4.2 in this release. 
• The camel-jms Maven pom.xml file now exclude spring-messaging dependency as this JAR is not used.
• Unit testing Camel with Spring Boot and extending the base classes CamelTestSupport or CamelSpringTestSupport is now throwing an exception as this has never been intended/support. Instead use the CamelSpringBootRunner JUnit runner, and do not extend a base class.
• The file consumer has changed to use readLock=none as default instead of readLock=markerFile. Documentation already indicated that readLock=none was the default.
• The SEDA component now has a default queue size of 1000 instead of unlimited. 
• Upgraded camel-bean-validator to Bean Validation API 2.0 (JSR 380 - Bean Validation 2.0) is part of JEE 8, and as therefore camel 2.22.0 may not be running on Java EE 7 server.
