+Feature: #107581 - Improve handling of FinisherException
+========================================================
+
+See :issue:`107581`
+
+Description
+===========
+
+:php-short:`\TYPO3\CMS\Form\Exception\FinisherException` instances thrown during
+form processing are now caught within their respective finisher. Instead of
+resulting in a generic 503 error page, the exception is logged, and a
+user-friendly error message is displayed to the user, indicating that the form
+could not be submitted successfully.
+
+The error message can be customized for each finisher using the new
+:yaml:`errorMessage` option. Additionally, the newly introduced *Error*
+template can be overridden and customized.
+
+Impact
+======
+
+Users no longer see a 503 error page if a FinisherException occurs. Instead,
+they receive a clear, user-friendly message in the form frontend.
+All FinisherExceptions are logged for further analysis and debugging.
+
+This change improves the user experience and makes error handling in forms
+more flexible and transparent.
