+### Statamic will now use your app's default pagination view
+**Affects apps using the `auto_links` pagination variable in templates.**
+
+Previously, Statamic used the `pagination::default` view to rendering pagination links. In Statamic 5, it will use your app's default pagination view, typically `pagination::tailwind`. 
+
+To avoid making code changes, you may wish to change the default view back to `pagination::default`:
+
+```php
+// app/Providers/AppServiceProvider.php
+
+use Illuminate\Pagination\Paginator; // [tl! ++]
+
+public function boot(): void
+{
+    Paginator::defaultView('pagination::default'); // [tl! ++]
+}
+```
