 ## Bugs Fixed
 
+- **Entity:** Fixed a bug where `Entity::toRawArray()` returned a `Time` instance for a date attribute that had been assigned a string value, while the same attribute was returned as a string when the entity was populated from the database. `toRawArray()` now returns the string representation of date attributes in both cases.
 - **Security:** Fixed a bug where `Security::__construct()` threw a `TypeError` when the CSRF cookie was an array, causing an HTTP 500 response for affected requests.
 - **Worker Mode:** Fixed a bug where every request that ended with an uncaught exception, including a `404 Page Not Found` without a 404 override, called `exit()` in the exception handler. This ended the worker script, so FrankenPHP booted a new one, and the worker loop skipped its cleanup after the request. The exception handler now returns to the worker loop.
