Semantic version number

Laravel release notice clarifies Semantic control for Laravel 6.0 and later versions:

Laravel framework (Laravel /framework) package follows the Semantic Versioning standard. This keeps the framework consistent with other first-party Laravel packages that already follow this versioning standard. Laravel's release cycle will remain unchanged.

Optimize authorization response

Before this, it was very difficult to provide custom error messages to end users around authorization policies. Laravel6 provides the Gate::inspect method to authorize policy responses. ：

$response = Gate::inspect('view', $flight);
if ($response->allowed()) {
    // 用户已授权...
}
if ($response->denied()) {
    // 用户未授权，返回响应信息
    echo $response->message();
}

Task middleware

Task middleware allows middleware to filter queue tasks:

// 在任务类中定义中间件方法
public function middleware()
{
     return [new SomeMiddleware];
}
// 分发任务时可通过through指定中间件
SomeJob::dispatch()->through([new SomeMiddleware]);

Using middleware can avoid Write code that has nothing to do with the main business logic in the handle() method of the task class.

Lazy Collections

Lazy collections are a game-changer for collections that deal with large amounts of data (including Eloquent model collections). A new lighting \Support\LazyCollection class leverages PHP's generators to keep memory low when working with large data sets. Check out the Lazy Collections documentation for more details on this impressive new feature!

Eloquent Subquery Enhancements

Laravel UI

The front-end scaffolding that comes with Laravel 5.x is now separated into an independent laravel/ui Composer package. This allows for easy iteration of UI scaffolding outside of the main framework.

If you want to build with traditional Bootstrap/Vue/, you will run the following command:

composer require laravel/ui
php artisan ui vue --auth
