What is the easiest way, without having to create your own utility, to set the default service version to the latest in Azure Blob Storage ?

There is basically nothing to be set in the Azure portal and I am having a difficult time finding working utilities to use for Azure.

For some reason Azure is defaulting to the oldest version which does not send things like the http range header for example.

Any utility that can do this ? Thank you.
