There were various updates in https://github.com/JetBrains/phpstorm-stubs/commits/master/cassandra/cassandra.php which should be incomporated in your documentation.
And then it would be good if this documentation is not using the old Datastax repository as reference but gets updates from yours (as you are the now defacto upstream). And this documentation is then for example used by phpstan and similar tools to validate PHP code.
@JetBrains, any recommendations how this can be achieved?
