just a type correction and suggestion on adding a comma and one word (ie 'by') to make it more easily to be understand.

Re-implemented RBAC by following more closely to the original NIST RBAC model. Dropped `yii\rbac\PhpManager`.

fixes #1581 and #3013

added a hint and link

RBAC Rule small fix

Pretty awesome feature!

Note: should confirm that my additions of “inclusive” is correct.

Still feels like an incomplete, possibly unnecessary, fragment

Because we’re using capital “Web” not “web” (my previous mistake).

One paragraph description and one code snippet to clarify usage of yii\web\View::render() in a view context, as using echo is a significant change from partial view usage in Yii 1.1.

Currently `Yii::$app->log` is not the `yii\log\Logger`, but the `yii\log\Dispatcher`. Logger is transient component used indirectly and separately by the dispatcher and helper methods for logging.

fixes #2989

Improved action filter and action execution flow by supporting installing action filters at controller, module and application levels
