In the past, there's been some Microsoft Project security updates that have caused adverse results in working with the MSP New Driver. Is regression testing recommended to be done on a customer workstation prior to installing a Microsoft Project update? 

Release : All Supported Releases

Component : CA PPM SAAS MICROSOFT PROJECT (MSP)

• As of September 2017,  there have been minimal issues with Microsoft Project Updates and the Clarity MSP Addin. So, it's no longer required to wait for the updates from Microsoft Project to be certified by the CA / Broadcom team before using (and we do not require regression testing done by the customer). 
• If there are any known issues with a security update, they will be published at: https://ca-broadcom.wolkenservicedesk.com/external/article?articleId=11553

          (see this KB for more details on MSP Certification testing)

• Additionally, for any significant Windows 7 or Windows 10 updates, it's recommended to do basic testing of the interface (make sure users are able to open a project to MSP/save the project back)
