Laravel 12: A Deep Dive into the Latest Features and Updates

As we move through 2025, Laravel continues to evolve and strengthen its position as one of the most popular PHP frameworks. With the release of Laravel 12, let's explore the significant improvements and features that make it an even more powerful tool for web development.

What's New in Laravel 12?

1. Enhanced Type System

Laravel 12 brings comprehensive type hinting across the framework, leveraging PHP 8.2's powerful type system. This means better IDE support, fewer runtime errors, and more maintainable code.

public function store(StoreUserRequest $request): JsonResponse
{
    $validated = $request->validated();

    $user = User::create($validated);

    return response()->json([
        'message' => 'User created successfully',
        'user' => $user
    ], 201);
}

2. Process Interaction API

The new Process facade provides a beautiful abstraction for handling external processes:

use Illuminate\Support\Facades\Process;

$result = Process::run('ls -la');
return $result->output();

// Concurrent processes
[$first, $second] = Process::concurrently(function (Pool $pool) {
    $pool->command('cat first.txt');
    $pool->command('cat second.txt');
});

3. Laravel Pennant

Feature flags made easy with the new Laravel Pennant package:

use Laravel\Pennant\Feature;
use Illuminate\Support\Lottery;

Feature::define('new-onboarding-flow', function () {
    return Lottery::odds(1, 10);
});

if (Feature::active('new-onboarding-flow')) {
    // Show new onboarding experience
}
