For details, see MCP integration in the OpenText Performance Engineering for Developers Help Center.

Cloud and SaaS

This release includes the following cloud and SaaS updates.

Area Enhancement
Startup scripts

Startup script support was extended to Azure cloud load generators on Windows and Linux, and to AWS cloud load generators on Linux.

For details, see Run startup scripts.
Azure Resource Group configuration

Azure cloud hosts can now use predefined Resource Groups. This provides more granular access control by assigning the Service Principal Contributor role to the Resource Group level only.

For details, see Use predefined Resource Groups in Azure accounts.

Integrations and ecosystem

This release includes the following integrations and ecosystem updates.

Area Enhancement
Core Performance Engineering Analysis

This integration includes the following analysis enhancements:
