T93210 is said to be in "May-June" column of the Roadmap project. Till short ago, that column was named "April-something". I can't see the change logged anywhere, be it https://phabricator.wikimedia.org/project/profile/1109/ or elsewhere.
Changes to column names are logged in the Phabricator database. Example query:
SELECT project_columntransaction.oldValue, project_columntransaction.newValue, project_columntransaction.dateModified, project_columntransaction.authorPHID, project_column.projectPHID FROM project_columntransaction JOIN project_column WHERE project_columntransaction.transactionType = "project:col:name" and project_columntransaction.dateModified > 1446395000 AND project_columntransaction.objectPHID = project_column.phid;
(you might want to improve this query by replacing projectPHID and authorPHID by their actual human-readable values)
