Upgrade notes

Package renaming

To make the Flowable modules compatible with OSGi and Java 9 modules some package renaming was needed to prevent clashes. The renaming has been done according to this pattern org.flowable.engine.common -> org.flowable.common.engine

StrongUuidGenerator usage with Spring Boot

The Spring Boot process auto configuration now uses the StrongUuidGenerator. In case you were overwriting the default one you can remove that. In case you want to keep using the DbIdGenerator, then just add the following bean to your configuration:

   @Bean

    public EngineConfigurationConfigurer processEngineDbIdGeneratorConfigurer() {

        return engineConfiguration -> engineConfiguration.setIdGenerator(new DbIdGenerator());

    }

The default values of the DbIdGenerator would be filled in during the creation of the Process Engine.

IdmEngineConfigurator

The default IdmEngineConfigurator and SpringIdmEngineConfigurator have been moved from org.flowable.app.engine.impl.cfg and org.flowable.spring.configurator to org.flowable.idm.engine.configurator and org.flowable.idm.spring.configurator respectively. In case you have used them please replace your imports.

Async history classes package change

The async history classes have been moved from the process engine module to the job service, to make them available for other components. Generally, the packages now have job.service added to make this clear.

Classes with regards to async history collection and execution (AbstractAsyncHistoryJobHandler, AsyncHistoryJobHandler, AsyncHistoryListener, AsyncHistorySessionFactory, AsyncHistorySession, DefaultAsyncHistoryJobProducer, HistoryJsonTransformer) in the org.flowable.engine.impl.history.async have been moved to the org.flowable.job.service.impl.history.async package.

Updating the imports is sufficient when upgrading.
