 The class `Doctrine\ORM\Mapping\Driver\DatabaseDriver` is deprecated without replacement.
 
+## Add `Doctrine\ORM\Query\OutputWalker` interface, deprecate `Doctrine\ORM\Query\SqlWalker::getExecutor()`
+
+Output walkers should implement the new `\Doctrine\ORM\Query\OutputWalker` interface and create
+`Doctrine\ORM\Query\Exec\SqlFinalizer` instances instead of `Doctrine\ORM\Query\Exec\AbstractSqlExecutor`s.
+The output walker must not base its workings on the query `firstResult`/`maxResult` values, so that the 
+`SqlFinalizer` can be kept in the query cache and used regardless of the actual `firstResult`/`maxResult` values.
+Any operation dependent on `firstResult`/`maxResult` should take place within the `SqlFinalizer::createExecutor()`
+method. Details can be found at https://github.com/doctrine/orm/pull/11188.
