• The Werkzeug model has been changed to use API graphs. When defining new models for classes based on the MultiDict and FileStorage classes in werkzeug.datastructures, the relevant extension points are now the two InstanceSourceApiNode classes in the semmle.python.frameworks.Werkzeug module, instead of InstanceSource. The latter classes have now been deprecated.
