The official support deadline for people to upgrade their Azure AD Connect version 1.x installations may have passed,(August 31st, 2022), but many organizations are still in the process of migrating to Azure AD Connect v2.x.
Microsoft addressed two issues:
Loop during upgrade from v1.6.x
Microsoft addressed an issue where the upgrade from version 1.6.x to version 2.1.x got stuck in a loop due to IsMemberOfLocalGroup enumeration.
Validation of Enterprise Admin credentials
Microsoft addressed an issue where the Azure AD Connect Configuration Wizard was sending incorrect credentials (username format) while validating if the user account is a member of the Enterprise Admins group in Active Directory.
Version 184.108.40.206 of Azure AD Connect was made available for download as a 144 MB weighing AzureADConnect.msi on October 5th, 2022.
