The Savings Breakdown now offers a more granular view for complex applications composed of multiple components (apps). This **Application Under Test (AUT) Breakdown** feature empowers you to gain a deeper understanding of the tested component versions and the source of code changes within your integration app.

**Key Features:**

* **Component-Level Details:** View the specific app, branch, and build associated with each component.
* **Build Monitor Access:** Admin and DevOps users can access the Build Monitor for in-depth technical details related to each component's build.
* **Component Modification Status:** Analyze the status of each app compared to the previous build of the main application. This information helps identify which components triggered additional testing due to code changes.
