Az version 1.0 Released

Microsoft's Azure Team has announced the release of Azure PowerShell ‘Az’ Module version 1.0.

Earlier, in August 2018, the Azure team had released the initial version of a new Azure PowerShell Module, 'Az' which combines the functionality of the AzureRM and AzureRM.NETcore modules. Now, the company has released version 1.0 of Azure PowerShell ‘Az’ Module.
According to the company, with Az, Windows PowerShell and PowerShell Core users get the latest Azure tooling in every PowerShell on every platform. Furthermore, it also simplifies and normalizes Azure PowerShell cmdlet and module names.
Azure PowerShell module Az features the following:
"Az runs on Windows PowerShell 5.1 and PowerShell Core (cross-platform)
Az is always up to date with the latest tooling for Azure services
Az ships in Cloud Shell
Az shortens and normalizes cmdlet names – all cmdlets use ‘Az’ as their noun prefix
Az simplifies and normalizes module names – data plane and management plane cmdlets for each service use the same Az module
Az ships with new cmdlets to enable script compatibility with AzureRM (Enable/Disable-AzureRmAlias)
Az enables device code authentication support, allowing login when remoting via a terminal to another computer, VM, or container"
