Other Noteworthy Stuff

• ⚠️ Wikidata Query Service graph split: As you know Wikidata Query Service was no longer able to handle the complete set of data Wikidata has. To address this the graph in Wikidata Query Service has now been split into a main graph (that continues to be at query.wikidata.org) and a scholarly graph (that is at query-scholarly.wikidata.org). For more details please see Wikidata:SPARQL query service/WDQS graph split.
• Join the Wikidata:Impact stories global campiagn. We're celebrating the amazing Wikidata community - editors, developers, librarians, and creators - and inviting you to share how Wikidata is used.
