New Fetures in Laravel 8
1. app/Models Directory
The artisan:make model command will create the model in the app/Models directory. This feature was decided after Taylor asked people on Twitter how they feel about this.
2. New Landing Page
Laravel 8 comes with a new landing page for a brand new install. It is now redesigned and It is built using TailwindCSS, includes light and dark-mode capabilities, and by default extends links to SaaS products and community sites.
3. Controllers Routing Namespacing
No more double prefix issues! In previous versions of Laravel, the RouteServiceProvider had an attribute called namespace that was used to prefix the controllers in the routes files. That created a problem when you were trying to use a callable syntax on your controllers, causing Laravel to mistakenly double prefix it for you. This attribute was removed and now you can import and use it without the issue.
It can also be used for single action controllers that have the __invoke method.
4. Route Caching
Laravel uses route caching to compile your routes in a PHP array that is more efficient to deal with. In Laravel 8, it’s possible to use this feature even if you have closures as actions to your routes. This should extend the usage of route caching for improved performance.
5. Attributes on Extended Blade Components
In Laravel 7 the child components didn’t have access to the $attributes passed to it. In Laravel 8 these components were enhanced and it is now possible to merge nested component attributes. This makes it easier to create extended components.
6. Better Syntax for Event Listening
In the previous versions of Laravel, when creating a closure based event listener there was much repetition and a cumbersome syntax.
7. Queueable Anonymous Event Listeners
In Laravel 8 it is possible to create queueable closure from anywhere in the code. This will create a queue of anonymous event listeners that will get executed in the background. This feature makes it easier to do this, while in previous versions of Laravel you would need to use an event class and an event listener (using the ShouldQueue trait).
8. Maintenance Mode
This is especially useful when you need to do some maintenance on your application and you want to take it down for your users but still let your developers investigate bugs. This will create a secret cookie that will be granted to whoever hits the correct endpoint, allowing it to use the application while in maintenance mode.
Pre-rendering an error view is a safe way for not exposing errors to your end user when your application is down (during a new deployment, for example). The Laravel 8 framework guarantees that your predefined error page will be displayed before everything else from the application.
This combines the new features and will make the application only display a single predefined route, while still allowing for the people who have the secret to test and debug. This can be very useful when launching a new app.
9. Model Factories
Model factories are class based factories that add a lot of new features to Laravel 8. For each model there’s also a factory class, where there is a definition method that says which attributes it will generate for that model. Your models make use of that factory through the Factory trait.
10. Laravel Jetstream
Laravel Jetstream is a brand new scaffolding for Laravel released as an open-source package. It builds an application using TailwindCSS and TailwindUI, includes login, registration, two-factor authentication, session management. It offers two versions for handling frontend: Livewire (TALL Stack) or InertiaJS (VueJS).

What is Laravel ?
Laravel is a PHP framework which was introduced for the web artisans.Now a days it's a popular framework among the students as well as the enterprise level developers, since it's more described and meaningful framework.Taylor Otwell, the writer of the framework is more innovative rather than other colleagues in his time in higher education.He was thought to write a framework instead of writing an applications which were done by other colleagues.
MVC architecture has been become a very popular concept since the start of 21st century.By the definition M stands for MODEL ,V stands for VIEW and C stands for CONTROLLER.This three components are determined the whole system/project (an application or a software).The model represents the database.The view represents the rendering output that means the human-interacted interface and the controller represents the logical functionality of the software.
