 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
 
-It selects automatically the best possible hasher. Currently, it tries to use

-not possible. In the future, when PHP adds new hashing techniques, it may use
-different password hashers.
+It automatically selects the best available hasher. Starting from Symfony 5.3,
