Upgrading To 9.0 From 8.x
Likelihood Of Impact: Low
Laravel's dependency on
opis/closure has been replaced by
laravel/serializable-closure. This should not cause any breaking change in your application unless you are interacting with the
opis/closure library directly. In addition, the previously deprecated
Illuminate\Queue\SerializableClosure classes have been removed. If you are interacting with
opis/closure library directly or using any of the removed classes, you may use Laravel Serializable Closure instead.
We also encourage you to view the changes in the
laravel/laravel GitHub repository. While many of these changes are not required, you may wish to keep these files in sync with your application. Some of these changes will be covered in this upgrade guide, but others, such as changes to configuration files or comments, will not be. You can easily view the changes with the GitHub comparison tool and choose which updates are important to you.
