Microsoft Open Source Blog 
In order to provide more clarity into what’s changed in each Terraform AzureRM provider release, we’re kicking off a blog series that will provide the highlights for each release. We will continue to provide details on every release in the Change Log for the provider within the GitHub repo as well.
If you are looking for what’s coming up in future releases, we are marking issues that we expect to include in the next release or two by adding the appropriate milestones, which correlate with the release versions. For these details, you can check out the milestones section of the AzureRM repo.
Release highlights
The v1.22 release includes a few new resources, which are duplicates of existing resources. The purpose of this is to correct some invalid naming so that we can remove the mis-named resources in the next major version of the Provider (version 2.0.0). Unless otherwise noted each new resource provides the same functionality as the depreciated resource.
