I just generated the docs without the changes, comitted the results (`reference` and `xml` directories) into a new GIT repository and did the same with the changes applied. The resulting diff is only about the generated timestamps and the following:
```diff diff --git a/xml/Doxyfile.xml b/xml/Doxyfile.xml index 5cb5962..c88d929 100644 --- a/xml/Doxyfile.xml +++ b/xml/Doxyfile.xml @@ -362,7 +362,7 @@ <option id='DOT_FONTNAME' default='yes' type='string'><value><![CDATA[Helvetica]]></value></option> <option id='DOT_FONTSIZE' default='yes' type='int'><value>10</value></option> <option id='DOT_FONTPATH' default='yes' type='string'><value><![CDATA[]]></value></option> - <option id='CLASS_GRAPH' default='no' type='string'><value>TEXT</value></option> + <option id='CLASS_GRAPH' default='yes' type='string'><value>YES</value></option> <option id='COLLABORATION_GRAPH' default='yes' type='bool'><value>YES</value></option> <option id='GROUP_GRAPHS' default='yes' type='bool'><value>YES</value></option> <option id='UML_LOOK' default='yes' type='bool'><value>NO</value></option> ```
So yes, the `CLASS_GRAPH` setting is changed implicitly. But everything in the generated files is identical to before, so it seems to be not relevant for us.
