Today, July 14, 2017, we released a new version of the Upgrade Readiness Deployment script.
In version 2.1, we made some improvements to make sure that the checks that the script makes to verify connectivity to Microsoft endpoints, works smoothly. Script version 2.1 only supported running this improved checks on x64 machines. In this release, we are adding support to make those checks on x86 machines, and includes all the improvements made in 2.1 with no other changes.
You can find the latest script and the Readme file that includes the details of these changes on the Microsoft Download Center.
