# Apr 2025 Release Notes (RUX)

### The Respond UX April release (2025.04) includes:

**Improved Search by Sensor Name**

We've enhanced the search functionality on the Detections page to support searching by Sensor Name instead of the internal Sensor LUID. This update addresses customer feedback and makes it easier to find detections associated with specific sensors using recognizable names.

**Enhanced Detection for Copilot Abuse in M365**

In response to strong customer interest, we’re expanding protection against potential abuse of Microsoft Copilot. In addition to the existing M365 Suspicious Copilot Access detection (which flags access from unusual locations), we’re introducing a new detection: M365 Copilot Sensitive Data Discovery. This identifies attacker behavior attempting to locate sensitive documents through Copilot in Microsoft 365.
