Flowable 7.0.0.M1 release
- This is the first milestone for version 7 of the Flowable Engines focusing on the Spring Boot 3, Spring 6 and Java 17 upgrade.
- The plan forward is to keep maintaining the 6.x and 7.x versions for at least the next year, so we will do both 6.x and 7.x releases.
- The REST application requires a servlet container / application server that supports Jakarta 9.
- This release focuses on the main Flowable Engines and REST APIs for the BPMN, CMMN, DMN and event registry engines. This means that there are no UI applications, no content and form engines and the modules for Mule and some others are removed.
Flowable 6.8.0 release
- Added support for using scripts in task and execution listeners and HTTP request and response handlers.
- Added support for new task and instance history levels to provide more options to reduce the amount of historic data stored.
- Added support to throw BPMN errors in scripts.
- Added support for headers in an event model that can be used with event registry events in case and process definitions.
- Improved support for starting case and process instances with the unique feature enabled on event registry start events. The event subscription for the event registry event is locked while starting the case and process instance to prevent any duplicate instances.
- Added support for async leave in addition to the already long existing async (before) attribute for async tasks in BPMN and CMMN. An async job will be created to execute the leave of a task when the async leave attribute is set to true.
- Improved support for parallel repeatable event listeners in case definitions.
- Added interface to provide an implementation for non-matching events that are received in the event registry.
- Added support to query directly on runtime variable instances both in the Java API and REST API.
- Improved housekeeping logic to reduce the throughput time.
- Added support for retries in Kafka channels in the event registry.
- Expose topic, partitions and offset consumer record for inbound Kafka channel and provide custom partition support for outbound Kafka channel.
- Added bulk support for deleting case and process instances, terminating case instances and moving deadletter jobs to executable.
- Added activity instance REST API query support.
- Fixed issue with event listeners in a repeatable stage in a case definition.
- Fixed issue with having multiple event registry start events in a process definition.
- Add dedicated task executor for the task invoker. This is fixing an issue with a potential deadlock when using the "true parallel" HTTP task feature.
- Improved channel definition caching logic to prevent channels from getting unregistered when they should not.
- Added support for providing an owner and assignee when starting a case or process instance.
- Upgrade to Spring Boot 2.7.6.
Flowable 6.7.2 release
- Fixed issue with vulnerable Log4j dependency. The Flowable apps now use the default Spring Boot logging framework, which is Logback.
- Added support to execute a decision service in the DMN REST API.
- Added support to query tasks with case instance variables.
- Fixed issue with migrating a process instance to a new process definition with a call activity and a new boundary event.
- Upgraded to Spring boot 2.6.2.
Flowable 6.7.1 release
- A case and process instance has support for a business status value, similar to a business key.
- Added support for deleting historic case and process instances and their related data using batches and batch parts.
- Fixed issue with the global lock mechanism when running a cluster of Flowable instances.
- Fixed issue with transient variables made persistent when passing all variables to a sub process instance with a call activity task.
- Added support for querying tasks, jobs and event subscriptions without the BPMN or CMMN entities. By using withoutProcessInstanceId on the task query for example you can make sure that only CMMN tasks and standalone tasks are returned without the BPMN tasks.
- Added MariaDB to the Flowable QA databases in Github Actions.
Flowable 6.7.0 release
- Implemented a global locking mechanism to have better support for using the async executor in a setup with multiple Flowable Engines. Together with this the async executor default configuration was changed to be able to handle more jobs per second by default. A 4-part article series describe all the fine details and a performance benchmark of this, https://blog.flowable.org/2021/04/14/handling-asynchronous-operations-with-flowable-part-1-introducing-the-new-async-executor/, https://blog.flowable.org/2021/04/21/handling-asynchronous-operations-with-flowable-part-2-components-configuration/, https://blog.flowable.org/2021/04/28/handling-asynchronous-operations-with-flowable-part-3-performance-benchmarks/, https://blog.flowable.org/2021/05/05/handling-asynchronous-operations-with-flowable-part-4-evolution-of-the-async-executor/.
- Added support for multi instance variable aggregation, https://blog.flowable.org/2021/02/16/multi-instance-variable-aggregation/. Aggregating values from a multi instance execution has always been tricky, but now with the support for variable aggregation this can be handled in an elegant way.
- Added support for case reactivation to support reactivating historic and completed case instances to a running case instance. Case definitions can have a case reactivation listener. that can be triggered to reactivate a historic case instance and the variable context etc will be re-created.
- A variable listener has been added to allow for BPMN and CMMN models to listen to changes for a specific variable and handle this trigger in the model.
- Add support for repetition signal and generic event listener in the CMMN engine to be triggered in parallel.
- Added an optimization flag for asynchronous multi-instance usage when the multi-instance is an automatic step or a sequence of automatic steps. If set, the engine will drastically lower resource consumption, and remove the optimistic locking exceptions and typically be more performant.
- Added support of synchronous handling of event registry events.
- Added support for DMN 1.3 version models.
- Added support for method overloading in JUEL / backend expressions.
- Added localization support for case definitions and runtime and history case instances and plan item instances.
- Added basic CMMN model validation to the CMMN engine.
- Added basic CDI support to the CMMN engine.
- Exceptions thrown from Task listeners are no longer wrapped in FlowableException.
- Exceptions thrown from Task, case lifecycle and plan item lifecycle listeners are no longer wrapped in FlowableException.
- Improved paging of runtime and historic process and case instance queries including variables. In earlier versions queries with include variables did paging in memory with a lot of limitations. This is now done on a query level and the limitations are not present anymore.
- In this release an upgrade to Spring Boot 2.5.4 and Spring 5.3.9 was done.
- There has been a change in the way a process / case instance is started from an event from the event registry. Instead of starting the process / case asynchronously, it is started synchronously. Using this default value allows correct processing of in-order event coming on the same topic. In case in order processing is not important you can configure that as part of your model by marking the Event Registry Start event as async or marking the Case Model as async. If you want to go back to the previous default you can set the following properties: flowable.process.event-registry-start-process-instance-async and flowable.cmmn.event-registry-start-case-instance-async to true.
