Before we jump into the new features, we’d like to point out that starting with version 6, Laravel now follows semver and will release a new major version every six months. You can see how the release process works here.
Laravel Jetstream
Laravel Jetstream improves upon the existing Laravel UI scaffolding found in previous versions. It provides a starting point for new projects, including login, registration, email verification, two-factor authentication, session management, API support via Laravel, and team management.
Models Directory
Laravel 8’s application skeleton includes an app/Models directory. All generator commands assume models exist in app/Models; however if this directory doesn’t exist, the framework will assume the application keeps models within the app/ folder.
Model Factory Classes
Eloquent model factories are now class-based starting in Laravel 8, with improved support for relationships between factories (i.e., a user has many posts). I think you’ll agree how awesome the new syntax is for generating records via the new and improved model factories:
use App\Models\User;
User::factory()->count(50)->create();
// using a model state "suspended" defined within the factory class
User::factory()->count(5)->suspended()->create();
Migration Squashing
If your application contains many migration files, you can now squash them into a single SQL file. This file will be executed first when running migrations, followed by any remaining migration files that are not part of the squashed schema file. Squashing existing migrations can decrease migration file bloat and possibly improve performance while running tests.
Improved Rate Limiting
Laravel 8 brings improvements to existing rate limiting functionality while supporting backward compatibility with the existing throttle middleware and offering far more flexibility. Laravel 8 has the concept of Rate Limiters that you can define via a facade:
use Illuminate\Cache\RateLimiting\Limit;
use Illuminate\Support\Facades\RateLimiter;
RateLimiter::for('global', function (Request $request) {
return Limit::perMinute(1000);
});
As you can see, the for() method takes the HTTP request instance, giving you full control over limiting requests dynamically.
Time Testing Helpers
Laravel users have enjoyed full control over time modification via the excellent Carbon PHP library. Laravel 8 brings this one step further by providing convenient test helpers for manipulating the time within tests:
// Travel into the future...
$this->travel(5)->milliseconds();
$this->travel(5)->seconds();
$this->travel(5)->minutes();
$this->travel(5)->hours();
$this->travel(5)->days();
$this->travel(5)->weeks();
$this->travel(5)->years();
// Travel into the past...
$this->travel(-5)->hours();
// Travel to an exact time...
$this->travelTo(now()->subHours(6));
// Return back to the present time...
$this->travelBack();
When using these methods, the time will reset between each test.
Dynamic Blade Components
Sometimes you need to render a blade component dynamically at runtime. Laravel 8 provides the <x-dynamic-component/> to render the component:
<x-dynamic-component :component="$componentName" class="mt-4" />

These are just a few of the new features in Laravel 8 and to see a complete list check out the Laravel 8 release notes as well as the upgrade guide. Also, don’t forget about Laravel Shift if you want an easy way of updating.
Taylor also gave a walkthrough of some of these features at Laracon Online and, you can still purchase a ticket if you’d like to see that. Also, Laracasts: What’s New in Laravel 8 series can help you get up-to-speed with new features in this release.
As with all releases, Laravel is made possible by so many people and, we’d like to thank everyone that contributes, that submits PR’s, that shares ideas, and that uses the framework. Laravel is truly a global team effort.
