What's New?

Change Description
Support for Amazon S3 Reduced Redundancy Storage A new storage option for Amazon S3 called Reduced Redundancy Storage (RRS) that enables customers to reduce their costs by storing non-critical, reproducible data at lower levels of redundancy than the standard storage of Amazon S3. It provides a cost-effective solution for distributing or sharing content that is durably stored elsewhere, or for storing thumbnails, transcoded media, or other processed data that can be easily reproduced. The RRS option stores objects on multiple devices across multiple facilities, providing 400 times the durability of a typical disk drive, but does not replicate objects as many times as standard Amazon S3 storage does, and thus is even more cost effective. Both storage options are designed to be highly available, and both are backed by Amazon S3's Service Level Agreement.

To facilitate changing the storage class of an object, the SDK provides a utility function, Amazon.S3.Util.AmazonS3Util.SetObjectStorageClass, that takes the name of the bucket, name of the object, the desired storage class (S3StorageClass.ReducedRedundancy or S3StorageClass.Standard) and a valid AmazonS3Client. Wrap a call to this method in a try...catch block in case of an exception.

Support for BootStrapActions for Amazon ElasticMapReduce The SDK supports the latest updates to Elastic MapReduce, including bootstrap actions.For more information about bootstrap actions, see Bootstrap Actions in the Amazon Elastic MapReduce Developer Guide.

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\<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>\".
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:
