Release: AWS SDK for Java 1.3.11

IAM Instance Profiles allow you to securely deliver AWS credentials directly to your Amazon EC2 instances. You can use the updated IAM API, or the AWS Management Console to create IAM Instance Profiles, then launch instances using that profile to have your AWS credentials securely distributed to the Amazon EC2 instances running your application.

The AWS SDKs make it easy to access the IAM Instance Profile credentials distributed through your EC2 instances. See below for more information on the new SDK client constructors and credentials provider implementations.

The Amazon EC2 and Auto Scaling APIs have also been updated so that you can launch instances or create Auto Scaling groups that take advantage of the new, easy to use, credentials distributions feature.

Each client in the AWS SDK for Java now includes a default constructor to make it even easier to work with the SDK. The default constructors use an AWSCredentialsProviderChain that chains together three new implementations of AWSCredentialsProvider that search for your AWS credentials in this order:

1. Environment Variables - AWS_ACCESS_KEY_ID and AWS_SECRET_KEY
2. Java System Properties - aws.accessKeyId and aws.secretKey
3. IAM Instance Profile - AWS credentials securely delivered directly to your Amazon EC2 instances

Developers are free to create their own custom implementations of AWSCredentialsProvider or custom chains of credentials providers using the AWSCredentialsProviderChain class.

Developers can now take advantage of reduced prices for Amazon EC2 Spot instances from their Auto Scaling groups.

The latest API update to Amazon S3 allows you to specify custom Access Control Lists (ACLs) when you upload objects. Previously you could specify a generic CannedAccessControlList at the same time as uploading an object, but the latest API update allows you to specify any custom ACL to be applied immediately when your object is uploaded.

The latest update to the Amazon RDS API adds support for option groups. Option groups are currently supported only for the Oracle DB engine. The first option to be supported is Oracle Enterprise Manager Database Control.

For more information, see the full release notes.

The latest update to the Amazon EC2 API allows you to export Windows Server instances that you originally imported into EC2, and adds timestamps to instance status and system status to indicate the date and time that a status check failed.
