Today, we have released Activiti 5.13. This release includes a big effort to improve our REST API. It now offers the same functionality as the Java API! We invite you to look at our new REST API in our userguide http://www.activiti.org/userguide/index.html . For backwards compatibility we also included our old REST API in the activiti-rest.war, but we recommend to use the new API when possible.
In addition to the REST API, this release also includes an out-of-the-box LDAP user and group manager implementation and it's now possible to include process and task variables in the result of process and task queries (both runtime as well as history). Of course we also include a lot of bug fixes and small improvements.
We hope you'll enjoy this new release and the new REST API in specific.
The Activiti team
