be attached to a query using Query::with(). Query::orderAsc() and Query::orderDesc() now accept Closure’s as their field enabling you to use build complex order expressions with the provided QueryExpression middlewares, i.e. classes with __invoke($request, $response, $next) method are deprecated. Instead use Closure with signature function($request, $handler) or classes which implement Psr\Http\Server\MiddlewareInterface deprecated. Instead use the className option. Datasource FactoryLocator::add() no longer accepts closure factory functions. Instead you must pass an instance of the LocatorInterface. Cake\Datasource\Paging\Paginator
