### Update Schema

The **Update Schema** feature allows administrators to safely update the database schema by importing new collection definitions.

#### Instructions:

* **Merge fields** – Safely add new fields to existing collections. Preserves all existing data.
* **System collections** (those starting with `_`) and the **users** collection are skipped automatically to prevent accidental overwrites.
* **Authentication required** – Only authenticated admins can perform schema imports.

To apply updates:

1. Click **Update Schema**.
2. Check the option **Merge fields with existing collections (safe - preserves data)** if applicable.
3. Confirm and apply the update.

The About System page ensures transparency by showing version, license, and release details while also giving administrators tools to safely update schemas without data loss.
