setup multisite in wp5

i already have muiltisite (v4) running on server, but wanted to test out V5.

wp-settings.php

/**

* Used to set up and fix common variables and include

* the WordPress procedural and class library.

*

* Allows for some configuration in wp-config.php (see default-constants.php)

// Initialize multisite if enabled.

if ( is_multisite() ) {

require( ABSPATH . WPINC . '/class-wp-site-query.php' );

require( ABSPATH . WPINC . '/class-wp-network-query.php' );

require( ABSPATH . WPINC . '/ms-blogs.php' );

require( ABSPATH . WPINC . '/ms-settings.php' );

} elseif ( ! defined( 'MULTISITE' ) ) {

define( 'MULTISITE', false );

}

So question is, does setting up multisite change in WP V5?

Do just set this to ‘true’? or do you still need to edit wp-config.php and .htaccess files?

thanks
