(*apologies for cross-posting*) Hello, This is a breaking change announcement relevant to those working with Lexeme dumps. In Lexeme dumps, "senses" and "forms" values, when not empty, are shown as arrays. When these lists are empty, they are currently displayed as objects. For example, values with content are displayed in array format: "senses":[{"id":"L4-S1",...] but empty values are treated as objects: "senses":{} However, empty lists should be presented as arrays as well: "senses":[] In this change, empty lists of forms and senses will be switched from objects to arrays. This adjustment makes the dumps more consistent and matches the same way non-empty values are presented. We will roll this change out on February 8th. We anticipate the impact of this change to be minimal and harmless for most use cases. Therefore, we haven't generated a test dump, as it would demand substantial resources and time. If you have any questions or concerns about this change, please don’t hesitate to reach out to us in this ticket ( T305660 <https://phabricator.wikimedia.org/T305660>). Cheers, -- Mohammed S.
