[Wikidata-tech] Changed JS API?

Hi Tech-Mailinglist, I'm using this gadget  here: https://www.wikidata.org/wiki/Wikidata:Tools/Enhance_user_interface#CiteTool in its current  incarnation here: https://www.wikidata.org/wiki/User:MichaelSchoenitzer/CiteTool.js It doesn't seem to work since the last few weeks, maybe because it calls on PropertyValueSnak, which seems to have moved since the last JS API version. https://doc.wikimedia.org/Wikibase/master/js/#!/api/PropertyValueSnak Is the API not ready to be stable yet, and how can this be fixed? Greetings Max
