Hello all,
As part of our work on data quality, and how we can make sure that data and references match, we have been working on a new notification to notify editors when they are *editing values without updating the reference*.
You can learn more about the feature and give feedback on this page https://www.wikidata.org/wiki/Wikidata:Mismatched_reference_notification_input. For now, the feature is deployed on test.wikidata.org. Based on your feedback, we may be able to enable it on wikidata.org in February 2020.
If you have comments or questions, please add them to the dedicated talk page https://www.wikidata.org/wiki/Wikidata_talk:Mismatched_reference_notification_input.
Thanks,
