Some enhancements were made this weekend to the Windows Azure Preview Portal. With these enhancements is the addition of Service Bus features and I think the ability to create Containers inside a Storage Account. I do not remember that being in place before.
As it relates to Virtual Machines I noticed the following two changes:
1. When you Capture An Image from an existing Virtual Machine you get a notice saying the Virtual Machine will be deleted.
2. When you delete a DISK you are now giving the option to also delete the underlying blob storage vhd associated with that DISK. This is a nice, money saving feature.
On a side note, it seems the ability to create and capture an Image is no longer working. I have been trying since Friday with no luck. It was working a few weeks ago. So if you are trying to create an Image you may run into issues.
