Activiti Release Notes

Release Notes - Activiti - Version 5.21.0

Highlights

This release contains some quite important bugfixes, more specifically

it fixes some cases where the end time was not set for activities in a process definition under certain conditions.
A concurrency bug was discovered when using delegateExpressions together with field injection. Make sure to read the updated documentation section on the use of 'delegateExpression'.

Included in this release is the 'secure scripting' feature (for javascript), which allows to execute scripts in a secure way. You can find the documentation in the 'advanced' section of the user guide.

All changes:

Improvement

[ACT-4064] - Missing some search filters in "Get historic task instances" REST service

Release Notes - Activiti - Version 5.19.0

Highlights

We introduced a new service DynamicBpmnService that allows you to change a defined set of properties of a process definition without needing to redeploy http://bpmn20inaction.blogspot.com/2015/10/adding-dynamic-behaviour-to-activiti.html
Improved support for the terminate end event. According to the BPMN spec a terminate end event should only terminate the current scope. So in case of a multi instance sub process, a terminate end event inside that multi instance sub process should only kill a single instance and the rest of the instances (of the multi instance) will continue. And in case a call activity kicks off a sub process, a terminate end event in the sub process will only kill the sub process instance, and the parent process will continue. We've added a new attribute on the terminate end event (activiti:terminateAll) that allows you to terminate all parent scopes if the value is set to true. By default only the current scope is killed.
ACT-4072 was fixed, a repeating timer (time cycle) now works according to the defined duration values

Improvements to the Activiti Modeler with terminate end events, cancel event and transaction support, and more intermediate catch and throw event support. Also, improvements to interrupting and non-interrupting solid and dashed line for boundary events.
Upgraded Spring dependency version to 4.1. Activiti is still working with Spring 4.0.x and 3.x as well
Various bug fixes

Known issues

There's a known issue with Chrome and the Activiti Explorer / Vaadin 6. You can get a blank screen in the details part of the Explorer. This is a known issue for Vaadin 6 and Chrome 43 and 44. There are bug fixes under way with Chrome 45, so that might fix it. Other browsers like Firefox work fine.

Backwards incompatible changes

https://activiti.atlassian.net/browse/ACT-2186 : When variables are removed, the historic variable entry is also removed. In earlier versions, the value of the historic variable was set to null.
https://activiti.atlassian.net/browse/ACT-4036 : when using an execution listener for the start event, in combination with multi instance, the behavior is changed. In 5.18, there will be one extra invocation of the execution listener (when entering the multi instance, without the loopCounter variable being said). For more information, check the section Multi instance and execution listeners in the user guide.

Release Notes - Activiti - Version 5.17.0

Highlights

We introduced a fully tested and brand new Async executor, which supersedes the old Job executor. The new Async executor uses less database queries to execute asynchronous jobs and is more performant in general. By default the Activiti Engine still uses the old Job executor, so you have to explicitly choose for the new Async executor by setting the asyncExecutorEnabled property in the process engine configuration. For more details you can look at the advanced section of the user guide.
The Activiti Modeler is fully revised and is implemented using Angular JS. This is donated from the Alfresco Activiti BPMN editor that's part of the Alfresco Activiti Enterprise offering. The new Angular JS Activiti Modeler is LGPL licensed. Note that some dialogs are not yet ported to the new Activiti Modeler, but you'll also find quite a bit of new functionality, including Mule and Camel tasks and being able to define a sequence flow order for an exclusive gateway. Any help with adding new features is really appreciated.
The user guide has been revamped with a rewrite to AsciiDoc
It's now possible to start a process instance a skip tasks based on a skipExpression. This is very handy when you are migrating process instances to the Activiti Engine (thanks to Robert Hafner for the pull request).
We added a new module named activiti-jmx to the Activiti project, which enables JMX for the Activiti Engine. Read Saeids blog for more details (thanks Saeid).
Variable fetching has been optimized for process instances and executions in general.
The database upgrade scripts use a different minor version than the JAR version. With the 5.17.0 release, the database version is 5.17.0.2. This versioning enables us to release snapshots and still be able to upgrade from a snapshot release to a stable release. For a 5.17.1 release the database version will be 5.17.1.x where x can be any number. So only the last minor version number can differ from the Activiti Engine release version.

Specific notes

Note that the version number is 5.17.0 instead of 5.17. Make sure you use version 5.17.0 for your Maven dependency.

Thanks to the community for the large number of pull requests, especially Martin Grofcik, Mike Dias and Saeid Mirzaei

Important Note for MSSQL and DB2 users

Activiti 5.13 and 5.14 contain changes to the default indexes that are created when using MSSQL or DB2 as database. These indexes are not created automatically when upgrading Activiti, as they may conflict with custom indexes or impact the database load. The purpose if the indexes is to avoid deadlock exceptions when using Activiti under high load.

As such, please review carefully following commits and apply to your database (where applicable):

Highlights

Fix for ACT-1591, with referential constraint error (JIRA link)

Small Explorer and Modeler bug fixes
Other small fixes

Important upgrade notes when using script tasks and auto storage of variables

Due to recent changes to the JDK (removing Serializable from sun.org.mozilla.javascript.internal.Undefined), the auto storing of variables is not possible anymore with the built-in Javascript scripting engine. See this link for more information. Each script variable that needs to be stored as process variable needs to be explicitly stored by calling execution.setVariable("variableName", variableValue).

For backwards compatibility reasons, the old behavior can still be used by setting the autoStoreVariables property on a scriptTask to true. As written in the linked article from above, this might not work when using a recent JDK version and the built-in Javascript scripting engine.

Release Notes - Activiti - Version 5.12

Highlights

Added new javascript-based diagram viewer to Explorer (thanks to Dmitry Farafonov)
Unified the BPMN parser and model for the Engine, Modeler and Designer
Added Activiti Kickstart to the Explorer to quickly create processes without deep BPMN knowledge
Simplified and extended the Activiti Camel module (thanks to Ryan Johnston)
Added first stage of reporting functionality to the Explorer via "reporting processes"
Added auto-layout module for Kickstart and BPMN import in Modeler (TBD) and Designer
Added script task and execution listeners
Lots of bug fixes

Important upgrade note

The internal org.activiti.engine.impl.bpmn.parser.BpmnParseListener interface and related classes have been removed.

Yes, we know many people relied on its capabilities, although it was a class in an internal package. But do not worry: we have introduced a replacement in the api package that offers similar (and even more powerful) functionality. The code is not backwards compatible, but the required changes should be minimal (eg the XML element is replaced by a Java pojo representation of the element). Read more about it in the new 'Advanced' chapter of the userguide.

Release Notes - Activiti - Version 5.11

Highlights

Added Activiti Modeler to the Activiti Explorer web application
Removed buggy demo script and replaced with simpler distribution
Support for doing queries that are not out-of-the-box possible with the query api (called 'native queries')
Enhanced ability to query for history variable values
Improved functionality to suspend and activate process definitions and instances
Improved Activiti QA and added DB2 and MSSQL servers
Added support for using a service call in aJava delegates (see here for more details)
Lots of bug fixes

Important upgrade note

In 5.11 we introduce a new history table for process variables. There is an optional migration database script that you can run to generate historic variables for existing process instances. This is optional because the engine will just create those records upon update of the variable if they don't exist.

The files can be found in the database directory of the Activiti distribution org/activiti/db/upgrade/optional.

API Change

The functionality of the repositoryService.suspendProcessDefinitionByXXX has been slightly altered. Previously, calling this method would stop the execution of jobs related to this process definition. Now, calling this method will not do this, but rather make sure a process instance cannot be created from this process definition. We've added a new method with an additional parameter 'suspendProcessInstances' which can be used to get the same behavior: when set to 'true', all the associated process instances will be suspended. This will avoid process instance continuation, including the execution of jobs related to the process instance.

Release Notes - Activiti - Version 5.7

Highlights

A new Activiti Explorer application completely rewritten in Vaadin
The REST services have been rewritten to Restlet

Important

A couple of add-on applications have spun off from the Activiti download and started life on their own. Activiti Modeler continues as a Google code project called Signavio Core Components. Activiti Cycle now lives on as Camunda Fox. An evolved version of Activiti KickStart will become part of a new Alfresco cloud case management solution.

Activiti Explorer has acquired Activiti Probe for an undisclosed amount :-) The resulting Activiti Explorer has been restyled and includes more dynamic task management features.

The REST services were rewritten with the Restlet framework with backwards compatibility, so the REST interfaces haven't changed. The previous versions of Activiti included a REST services web application that used the Spring Surf and Webscripts framework. To implement a new or revised REST service you had to learn these frameworks. With moving to Restlet implementing new or revised REST services has become really simple.

The demo setup has been limited to H2 database only, as many people struggled with getting the demo setup to run on their databases. The demo setup is a quick way to get familiar with Activiti and its tools, but it is by no means meant for production purposes. A section 'Changing the database' has been added to the userguide and is intended for advanced users who want to run the Activiti tools on their servers and databases.

Release Notes - Activiti - Version 5.6

Highlights

Added direct Mule and Camel integration
Easier way to retrieve businessKey from task listeners
Improved support for Alfresco processes
Added support for delegateExpressions in tasklistener
Added support for BPMN multi instance in the eclipse designer
Extended length of all user defined text columns to 4000

Known upgrade limitation

In the DB schema creation scripts, we've enlarged the max size of certain varchar columns from 255 to 4000. See ACT-236. These schema updates are not part of the automatic upgrade procedure.

Max length of following columns has been set to 4000:

ACT_RU_JOB.EXCEPTION_MSG_
ACT_RU_JOB.HANDLER_CFG_
ACT_RE_PROCDEF.RESOURCE_NAME_
ACT_RE_PROCDEF.DGRM_RESOURCE_NAME_
ACT_RU_TASK.DESCRIPTION_
ACT_RU_VARIABLE.TEXT_
ACT_RU_VARIABLE.TEXT2_
ACT_HI_TASKINST.DESCRIPTION_
ACT_HI_TASKINST.DELETE_REASON_
ACT_HI_DETAIL.TEXT_
ACT_HI_DETAIL.TEXT2_
ACT_HI_COMMENT.MESSAGE_
ACT_HI_ATTACHMENT.DESCRIPTION_
ACT_HI_ATTACHMENT.URL_

If you want to perform these changes, you can do that manually. Check your database capabilities for the easiest way on changing the type of columns from varchar(255) to varchar(4000). As a fall back, for each table affected, you can:

create a new temporary table
copy the contents from the original to the temporary table
delete the original table
recreate the original table using the new create script with the proper lengths
copy the contents from the temporary table back to the new original table
drop the temporary table

Release Notes - Activiti - Version 5.4

Compatibility note

After releasing 5.3, we discovered that execution listeners and task listeners and expressions were still in non-public api. Those classes were in subpackages of org.activiti.engine.impl..., which has impl in it). org.activiti.engine.impl.pvm.delegate.ExecutionListener, org.activiti.engine.impl.pvm.delegate.TaskListener and org.activiti.engine.impl.pvm.el.Expression have been deprecated. From now on, you should use org.activiti.engine.delegate.ExecutionListener, org.activiti.engine.delegate.TaskListener and org.activiti.engine.delegate.Expression. In the new publicly available API, access to ExecutionListenerExecution.getEventSource() has been removed. Apart from the deprecation compiler warning, the existing code should run fine. But consider switching to the new public API interfaces (without .impl. in the package name).

Highlights

Added first version of BPM-Roundtrip with Activiti Cycle (see this Screencast)
Started building case management features in the engine: Added dynamic comments, attachments and due dates to tasks in Activiti Engine

Release Notes - Activiti - Version 5.1

Warning

The automatic upgrade does not have enough coverage to have full confidence. For more info, see the user guide, section Database upgrade.

Changes

In attribute <serviceTask delegateExpression="..."> previously always performed a leave after calling the delegate that was obtained by evaluating the expression. Which means that it's always an automatic activity. Now the leave is only performed only when the delegate object implements JavaDelegate. In case the delegate object implements ActivityBehavior the leave will not be called. In that case, the ActivityBehavior is responsible for calling leave if it wants to be an automatic activity.
