 ## Unreleased
 <!-- Add all new changes here. They will be moved under a version at release -->
+* `NEW` using `enum (partial)`, it suggests all fields with the same `enum` type rather than just the fields from the current table.
+* `NEW` When using `enum["<key>" or <index>]`, undefined fields will raise an 'undefined' error.
 * `FIX` Renaming files in the directory leads to the auto-correction in "require" adding extra characters.
