+Migration and version compatibility (configuration arrays → named arguments)
+===========================================================================
+
+With TYPO3 v14, passing a configuration array as the first argument to Extbase
+attributes (for example :php:`#[Validate([ ... ])]`, :php:`#[IgnoreValidation([ ... ])]`,
+:php:`#[FileUpload([ ... ])]` or :php:`#[Cascade([ ... ])]`) has been deprecated
+(:ref:`Deprecation #97559 <changelog:deprecation-97559-1760453281>`).
+TYPO3 v14 introduces a property-based configuration syntax using named attribute
+arguments.
+
+The array-based syntax continues to work in TYPO3 v14 but will be removed with
+TYPO3 v15.
+
+..  important::
+
+    There is **no attribute configuration syntax that is compatible with both
+    TYPO3 v13 and TYPO3 v14**.
+
+    PHP attributes are parsed statically and cannot be conditionally defined
+    based on the TYPO3 version. Extensions supporting TYPO3 v13 and v14 in the
+    same release must therefore continue to use the array-based syntax and accept
+    the deprecation warning in TYPO3 v14.
