# Breaking Changes Ahead!

With the release of Sui **0.13.0** , we are replacing the concept of _Child Objects_ with new and improved _Dynamic Fields._ **This is a breaking change**.

Two things are happening with the Move API:

- Removed: `sui::transfer` methods `transfer_to_object` and `transfer_to_object_id`
- Added: `sui::dynamic_field` and `sui::dynamic_object_field`

Please read the [migration guide](https://sui.io/resources-sui/dynamic-fields-migration-guide/) for more information.
