Version 1.50 removed MB_Admin_Columns_User and MB_Admin_Columns_Post classes

Hi

I have been using the recomended technique to extend MB_ADMIN_COLUMNS with my own columns. This has been working fine but has completerly stopped with 1.50 - the following code throws fatal errors now.

   class SHS_Member_Link_Columns extends MB_Admin_Columns_Post {
        public function columns( $columns ) {
            $columns  = parent::columns( $columns );
            $this->add( $columns, 'member', 'Member', 'after', 'title' );
            $this->add( $columns, 'subscription', 'Subscription', 'replace', 'date' );
            // Add more if you want
            return $columns;
        }
        public function show( $column, $post_id ) {
            switch ( $column ) {
                case 'member':

MB_Admin_Columns_Post is no longer declared, nor MB_Admin_Columns_User
OK OK I spotted it - now need to extend \MBAC\Post or \MBAC\User and it all works fine - I suggest you update the docs and add something to thje update notes

Cheers
