Development

- Mismatch Finder https://www.wikidata.org/wiki/Wikidata:Mismatch_Finder: We are continuing the work on the review part of the system. We are now working on letting reviewers indicate if the mismatch is on Wikidata, the other database, both or neither. - Fixed a bug where it was possible for two Properties to have the same label in a given language by undoing/reverting an edit (phab:T289473 https://phabricator.wikimedia.org/T289473) - Fixed a confusing error message that was being shown when trying to save geoshape / tabular data that doesn’t exist (phab:T285758 https://phabricator.wikimedia.org/T285758) - Removing some unnecessary entity link formatting in edit summaries and special pages to improve performance (phab:T292203 https://phabricator.wikimedia.org/T292203) - Fixing an issue with invalid dates that the API accepts but should not (phab:T289417 https://phabricator.wikimedia.org/T289417) - Migrated all Wikimedia wikis to use the new change dispatching system. This system is responsible for notifying the other wikis about edits made on Wikidata that affect their articles so the article is refreshed and edits are added to recent changes and watchlists.
