Breaking: #72293 - API change in ExceptionHandlerInterface¶
\Throwable was added in PHP7 as new parent of
\Exceptions. So we
were in need to remove the type hint in forge#72117, which we now read as
\Exception as we only support PHP 7.0 or newer.
A fatal error will be thrown if you use own ExceptionHandlers implementing
TYPO3\CMS\Core\Error\ExceptionHandlerInterface "Fatal error: Declaration of ...
must be compatible with ..."
Installations which use an own ExceptionHandler implementing TYPO3s
\Throwable as type hinting in your implementation of
ExceptionHandlerInterface. Check the API/type hinting of the method where you
process the exception.
