The addition of new features for Windows Azure Storage is the latest step in the evolution of Microsoft's Cloud operating system. Starting with the end of the past month, Azure testers can enjoy Entity Group Transactions for Windows Azure Table, Copy Blob for Windows Azure Blob, Get Block List for Windows Azure Blob and API Versioning. Brad Calder explained that the new features introduced to Azure Storage were limited to the Windows Azure Storage REST interface and ADO.NET client library. However, the plan is to include the refreshes into a future version of the Azure software development kit.
