 ### Fixed
 
+- MongoDB: the connection form now shows a Username field. It was hidden for databases where authentication is optional, so connections to auth-enabled servers saved with no credentials and every query failed with "requires authentication" even though the connection looked healthy.
 - SQL import dropped statements when the database executed them slower than the file was parsed, so a re-imported export could fail with errors like "relation does not exist". The parser now waits for each statement to be consumed before reading more. (#1264)
 - SQL import ignored the database dialect, so PostgreSQL dumps with dollar-quoted function bodies were split at semicolons inside the body. (#1264)
 - SQL export emitted `DROP TABLE` for views, materialized views, and foreign tables, so re-importing failed with "is not a table". It now emits `DROP VIEW`, `DROP MATERIALIZED VIEW`, or `DROP FOREIGN TABLE` to match the object. (#1264)
