This beta release is ready for testers to check out the following functionality:

• Whoops container - try putting does_not_exists(); in your code to see if it appears.
• VarDumper tool - a simple variable dumper when you only want to see the value:
  Try these functions and provide feedback. Put this code in your theme's functions.php file:

add_action( 'loop_start', function() {
        global $wp_query;

	$array = [
		'ID'    => get_the_ID(),
		'title' => get_the_title(),
	];

	vd( $array );
        vddd( $wp_query );
} );

• Kint tool - more features such as call stack, memory size, and more.

add_action( 'loop_start', function() {
        global $wp_query;

	$array = [
		'ID'    => get_the_ID(),
		'title' => get_the_title(),
	];

	d( $array );

	s( $array );

        ddd( $wp_query );
} );

Feedback is greatly appreciated.
