# October 15, 2025: Unique ID field has moved from Project > Settings to Setup > ID fields

October 15, 2025

#### What’s changed?

* The field to select a unique ID (the field that we use to identify your items within Channable) has moved from **Project > Settings** to **Setup > ID fields**.
* We automatically select a unique ID for the items in your project. It is not necessary to check your unique ID until you use features in **Optimize**.
