Activiti

At its core is a super-fast and rock-solid BPMN 2 process engine for Java.

Activiti was designed to run in the cloud, Java application, on a server or on a cluster.

It integrates perfectly with Spring, it is extremely lightweight and based on simple concepts.

Proper documentation to get the user going is provided with the download package.

What is new in this release:

• 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.
• 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.
