Laravel 5.3.6 session problem

There is some changes in session in laravel 5.3, does that a problem

https://laravel.com/docs/5.3/upgrade

Heading "Session In The Constructor"

I don't think that is the problem because i tried everywhere in my class. I'm just trying the following simply thing:

session(['foo'=>'bar']);

Then I comment : //session(['foo'=>'bar']);

and add the follow code: $value = session()->all(); dd($value); In my session has nothing about 'foo'. PS: All of my routes are under web middleware group,and I'm using file storage about sessions if it matters.

I'm idiot ,just simply forgot about session->save(); :)
