 The `flush` method [was added to the `Illuminate\Contracts\Container\Container` contract](https://github.com/laravel/framework/pull/26477). If you are implementing this interface, you should add this method to your implementation.
 
+#### The `tagged` Method
+
+**Likelihood Of Impact: Very Low**
+
+The `tagged` method signature [has been changed](https://github.com/laravel/framework/pull/26953) and it now returns an `iterable` instead of an `array`. If you have type-hinted in your code some parameter which gets the return value of this method with `array` you'll have to modify the type-hint to `iterable`.

+#### The `resolve` Method
+
+**Likelihood Of Impact: Very Low**
+
+The `resolve` method [now accepts](https://github.com/laravel/framework/pull/27066) a new boolean parameter which indicates whether events (resolving callbacks) should be raised/executed during the instantiation of an object. If you are overriding this method, you should update the method signature to match its parent.

+**Likelihood Of Impact: Very Low**
+
+The `deleted_at` property [will now be automatically casted](https://github.com/laravel/framework/pull/26985) to a `Carbon` instance when your Eloquent model uses the `Illuminate\Database\Eloquent\SoftDeletes` trait. You can override this behavior by writing your custom accessor for that property or by manually adding it to the `casts` attribute:

+    protected $casts = ['deleted_at' => 'string'];

+The `send`, `sendNow`, `queue`, `later` and `fill` methods of the `Illuminate\Mail\PendingMail` class [have been changed](https://github.com/laravel/framework/pull/26790) to accept an `Illuminate\Contracts\Mail\Mailable` instance instead of `Illuminate\Mail\Mailable`. If you are overriding some of these methods, you should update their signature to match its parent.

+The `markdownComponentPaths` method [has been renamed](https://github.com/laravel/framework/pull/26938) to `textComponentPaths`. If you are overriding this method, you should update the method name to match its parent.

+All `array_*` and `str_*` global helpers [have been deprecated](https://github.com/laravel/framework/pull/26898) and will be removed in Laravel 5.9. You should use the `Illuminate\Support\Arr` and `Illuminate\Support\Str` methods directly.

+
+The `defer` boolean property on the service provider which is/was used to indicate if a provider is deferred [has been deprecated](https://github.com/laravel/framework/pull/27067). In order to mark the service provider as deferred it should implement the `Illuminate\Contracts\Support\DeferrableProvider` contract.

 Therefore, when using Laravel 5.8, emails that were previously incorrectly considered invalid will now be considered valid (e.g `hej@bär.se`).  Generally, this should be considered a bug fix; however, it is listed as a breaking change out of caution. [Please let us know if you encounter any issues surrounding this change](https://github.com/laravel/framework/pull/26503).
