Version 25.3 contains the following new features and enhancements.

Area	Enhancement
Performance Engineering Aviator (Beta)	Aviator for Scripting in VuGen provides assistance with many aspects of the scripting process. Using AI assistance before, during, and after the scripting process can help to save time and simplify script creation. Aviator can assist with tasks such as selecting the best protocol for an application scripting session, error analysis and remediation, function and coding assistance, script optimization, and script summarizing. When combined, these assisted actions can yield significant time savings, while also reducing required scripting skill sets. All users, from new to experienced performance engineers, will welcome Aviator's partnership in the scripting process. Aviator for Analysis in OpenText Core Performance Engineering Analysis redefines how teams approach performance analysis. It helps accelerate investigations, increase productivity, and streamlines the onboarding of new team members. Through conversational analysis, performance engineers can interact with Aviator using natural language directly within the dashboard environment. When you ask for summaries, trends, anomalies, or detailed insights, Aviator delivers clear, contextual answers about critical metrics. By leveraging Aviator’s capabilities, teams can significantly reduce the time spent diagnosing errors, and move faster from detection to resolution with actionable guidance.
