Hello,  
We have flowable engine 6.6.0 embedded in our project. Default history level is “FULL” set with SpringProcessEngineConfiguration and it works fine.  
But changing history level inside process definition doesn’t work at all. I see that flowable modeler adds extension element to schema:

```auto
    <extensionElements>
      <flowable:historyLevel xmlns:flowable="http://flowable.org/bpmn"><![CDATA[none]]></flowable:historyLevel>
    </extensionElements>

```

But engine doesn’t react to it, history level for process instance is still FULL. I can see process instance, tasks and all variable updates in history tables after finishing my process.  
Here’s process definition example:

```auto
<?xml version="1.0" encoding="UTF-8"?>
<definitions xmlns="http://www.omg.org/spec/BPMN/20100524/MODEL" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:flowable="http://flowable.org/bpmn" xmlns:bpmndi="http://www.omg.org/spec/BPMN/20100524/DI" xmlns:omgdc="http://www.omg.org/spec/DD/20100524/DC" xmlns:omgdi="http://www.omg.org/spec/DD/20100524/DI" typeLanguage="http://www.w3.org/2001/XMLSchema" expressionLanguage="http://www.w3.org/1999/XPath" targetNamespace="http://bpmn.io/schema/bpmn">

Did you set enableProcessDefinitionHistoryLevel on the process engine configuration to true?

No, I didn’t 🙂  
Thanks a lot, it works fine now.
