After a little bit more than a month in preview, Microsoft has announced the general availability for Azure AD PowerShell v2.0

This new version does not provide (yet) full functional parity with the older Microsoft Online module.

The current Microsoft Online PowerShell module will not be updated anymore.

You can get more details about what is included in this version 2.0 here https://docs.microsoft.com/en-us/powershell/azuread/v2/azureactivedirectory while you can install it from https://www.powershellgallery.com/packages/AzureAD/2.0.0.33
