Difference between latest release and master

[matejdr]

Hi, just got an error Use of "parent" in callables is deprecated today.
Then I check the latest code in master and the problem was fixed several months ago👍
But the change does not reflect in the latest release, any reason for that?

    call_user_func_array(array(parent::class, '__construct'), func_get_args());
