Azure November 2014 update changed subscription file format to JSON

After updating my Powershell with the November 2014 updates, the Import-PublishedSettingsFile commandlet is creating a subscription file in JSON format instead of XML.

How do I get a file in XML format? There are not output format options.

BACKGROUND The change appears to be causing an invalid account error when I attempt to run commandlets that rely on the current subscription. One example is Get-AzureService which returns this error:

Get-AzureService : Account with name '68BC909D63F2A51F987005620552FB1D643E03DE' does not exist. Parameter name: accountName At C:\UtilityScripts\Modules\AzureVdcConfigFileGenerate\AzureVdcConfigFileGenerate.psm1:189 char:42 + [object] $script:aSourceVdcService = Get-AzureService -ServiceName $sSourceV ... + ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + CategoryInfo : NotSpecified: (:) [Get-AzureService], ArgumentException + FullyQualifiedErrorId : System.ArgumentException,Microsoft.WindowsAzure.Commands.ServiceManagement.HostedServices.GetAzureServiceCommand

I set up the subscriptions as follows:

Set-AzureSubscription -SubscriptionName  $sSourceSubscriptionName   -SubscriptionDataFile $sSourceSubscriptionFileName -CurrentStorageAccountName $sSourceStorageAccountName
Select-AzureSubscription -SubscriptionDataFile $sSourceSubscriptionFileName -NoDefault 
Select-AzureSubscription -SubscriptionDataFile $sSourceSubscriptionFileName -NoCurrent 
Select-AzureSubscription -SubscriptionName $sSourceSubscriptionName -current -SubscriptionDataFile $sSourceSubscriptionFileName 

The result is

SubscriptionId : b6f458b3-0228-48f4-8dec-b7a4884258c6

SubscriptionName : NameOfSubscription

Environment : AzureCloud

SupportedModes : AzureServiceManagement

DefaultAccount : 68BC909D63F2A51F987005620552FB1D643E03DE

Accounts : {68BC909D63F2A51F987005620552FB1D643E03DE}

IsDefault : False

IsCurrent : True

CurrentStorageAccountName : NameOfStorageAccount

I think the JSON format is causing the issue.
