 Bugs Fixed
 **********
 
+- **Entity:** Fixed a bug where ``toRawArray()`` returned ``Time`` objects instead of ISO-8601 strings for date fields. Now they are correctly converted to strings when ``$recursive`` is ``false``.
+
 - **Logger:** Fixed a bug where interpolating a log message with array or non-stringable context values could raise PHP warnings or errors.
