Version 2012-02-12
The 2012-02-12 version of Azure Storage includes these changes:
The Copy Blob operation now works asynchronously, and can copy from any Azure storage account.
Containers can be leased, and all leases support shorter or infinite durations. You must now provide a lease duration.
A released lease can't be broken or renewed. Previously, these operations were allowed.
If you break a lease that's being broken or is already broken, no error occurs.
The lease ID of an active lease can be changed.
A lease ID can be included on an operation to acquire a lease.
When you're breaking a lease, you can specify a period during which the lease should remain active.
Azure Table Storage and Azure Queue Storage now support shared access signatures.
A shared access signature can live longer than an hour, even with no stored access policy.
Azure Blob Storage now provides MD5 hashes for the Put Blob operation.
