+Additionally, Inertia provides an `InertiaRails.optional` method to specify that a prop should never be included unless explicitly requested using the `only` option:
 
 ```ruby
 class UsersController < ApplicationController
   def index
     render inertia: 'Users/Index', props: {
-      users: InertiaRails.lazy(-> { User.all }),
+      users: InertiaRails.optional(-> { User.all }),
     }
   end
 end
 ```
 
+> [!NOTE]
+> Prior to Inertia.js v2, the method `InertiaRails.lazy` was used. It is now deprecated and has been replaced by `InertiaRails.optional`. Please update your code accordingly to ensure compatibility with the latest version.

 On the inverse, you can use the `InertiaRails.always` method to specify that a prop should always be included, even if it has not been explicitly required in a partial reload.
