This werk only concerns developers of custom Checkmk extensions.

There are currently two ways for registering custom graph definitions:

graph_info["GRAPH_ID"] = GRAPH_DEFINITION

and

graph_info.append(GRAPH_DEFINITION)

Using the latter might have lead to duplicate graphs in the user interface. As of this werk, this is fixed.
