Az.ContainerRegistry Azure PowerShell module wasn't fully featured. Sometimes, PowerShell users had to take advantage of the Az CLI. We want to allow PowerShell user to be able to fully manage container images. Starting with Az.ContainerRegistry version 2.2.1, we will gradually be rolling out new cmdlets and new parameters. In this release, you can now fully manage (Get-, Remove-, Update-) repositories, manifests, and tags with increased performance.
