New Features

Change Description
Signature Version 4

We have released a new version of the protocol for authenticating inbound API requests to AWS Services. The new protocol, Signature Version 4, will enable AWS to support future growth and evolution of the AWS business. It introduces a specialized signing key, derived from the long-term AWS Access Key, which is used for the cryptographic signature. It also features incremental modifications in the canonicalization algorithm that streamline signature verification. For more information about Signature Version 4, go to Signature Version 4 Signing Process in the AWS General Reference.

Known Issues

Issue Description
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\\AWS SDK for .NET", and the install will complete successfully. If you are running on Vista, your personal folder is similar to "c:\users\\".
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. This is a known Windows Installer bug on Windows Vista, and is documented here:
