Description: 

To bring the Select query builder in line with the other database builders, the first parameter will become the Connection parameter. This is interesting if you override/extend the Select query builder. Mostly that will be contrib database driver developers.

From:

public function __construct($table, $alias, Connection $connection, $options = []) {}

To:

public function __construct(Connection $connection, $table, $alias = NULL, $options = []) {}
