Composer doens't update 'laravel/framework' package - laravel

Question

I'm trying to update my composer dependencies as I'm experiencing a weird error that in my Debug Pages I get the Symfony Page but not the Laravel one. As I tried to update my composer packages I saw that composer doens't even updates the laravel/framework package.
Composer output
Discovered Package: fideloper/proxy
Discovered Package: fruitcake/laravel-cors
Discovered Package: laravel/tinker
Discovered Package: nesbot/carbon
