+##2016.06.17 version 1.5.1
+* Azure Resource Manager
+  - Fix a bug in New-AzureRmResourceGroupDeployment. In some deployments the cmdlet throws an exception with "Deployment 'deploymentName' could not be found." and causes the cmdlet to fail. The fix makes sure the deployment is created before getting operations.
