+## Type hinting with template generics
+
+This release introduces of [template generic docblocks](https://phpstan.org/blog/generics-in-php-using-phpdocs) into Slim. If you type-hint `Slim\App` instance variable using `/** @var \Slim\App $app */`, then you will need to change it to either:
+
+* `/** @var \Slim\App<null> $app */` if you are not using a DI container, or
+* `/** @var \Slim\App<\Psr\Container\ContainerInterface> $app */` if you are.
+
+You can also type-hint to the concrete instance of the container you are using too. For example, if you are using [PHP-DI](https://php-di.org), then you can use: `/** @var \Slim\App<DI\Container> $app */`.
