|Support for Amazon EC2 API version 2009-11-30||This release introduces Spot Instances. Spot Instances are a new way to purchase and consume Amazon EC2 instances. They enable you to bid on unused Amazon EC2 capacity and run any resulting instances for as long as your bid exceeds the current Spot Price. The Spot Price changes periodically based on supply and demand. Spot Instances are complementary to On-Demand Instances and Reserved Instances, providing another option for you to obtain compute capacity. For more information, go to the Spot Instances Concepts section of the Amazon Elastic Compute Cloud Developer Guide or Amazon Elastic Compute Cloud User Guide.|
|Support for HEAD requests in GetPreSignedUrlRequest||The GetPreSignedUrlRequest class now has a Verb property to specify whether the request is made using HTTP HEAD or GET (default).|

|Installation Requires Administrator Privileges||The default install location is %PROGRAMFILES%, which on most computers is "c:\program files". In order to install files to the default location, the MSI must be run by an Administrator. If you don't have Administrator privileges on the machine, please change the install location to something like "c:\Documents and Settings\<you>\AWS SDK for .NET", and the install will complete successfully. If you are running on Vista, your personal folder is similar to "c:\users\<you>\".

Please update the References section of your Visual Studio solution as follows:
|Uninstalling the SDK produces "Unknown Publisher" message||On Windows Vista, uninstalling the MSI results in an "Unknown Publisher" dialog even though the installer is signed by Amazon Web Services.
