In L5 the models files are situated inside "app" folder. Controler inside "app/Http/Controllers" and views inside "resources/views".

And models are based in the "app/" directory :)

You can put your model anywhere you like, it's up to you.

Basically, if you are going to learn Laravel 5. All Laravel 4 => USELESS to you. I feel like i'm learning from scratch with Laravel 5. I recommend Laracasts.

Come on ezos86.. The changes between Laravel 4 to Laravel 5 isn't 10% compared to what was the L3 -> L4 transition.

No one forces you to upgrade if you don't want to.

And a lot of the community were already using PSR-4 namespacing, not using model & controller folders for a long time in L4. The directory structure changes was reflecting what the community does, nothing more.

I highly recommend Laracasts, very good examples for L5.

ezos, L3 and L4 were like Codeigniter, built for small to big applications, a lot of helpers and useful techniques but they let the user implement bad workarounds for everything, driving them to a bunch of messy coding and no OOP. With L5 they are "obligated" to implement S.O.L.I.D principles which are the foundation for maintainable, easy to read applications.
