What's New?

ChangeDescription
Support for the Asia Pacific (Singapore) Region

The AWS SDK for Java supports infrastructure services in the new Asia Pacific (Singapore) region.

For Amazon S3, you can create a bucket in the new region using the Region enumeration. For example:

s3.createBucket("my-singapore-bucket", Region.AP_Singapore);

For all other services, the region is set using the endpoint associated with the client object. For example:

AmazonEC2Client ec2 = new AmazonEC2Client(myCredentials);
ec2.setEndpoint("ec2.ap-southeast-1.amazonaws.com");
ec2.describeInstances();

Improved Idle Connection Management Idle HTTP connections are now released faster to avoid sockets sitting around in the CLOSE_WAIT state.
Logging Enhancements A warning message is now logged if the SDK detects that Saxon isn't being used for XPath processing.
Documentation Enhancements Continued documentation enhancements, particularly in the Amazon S3 client code.
Amazon S3 doesBucketExist The Amazon S3 client now has a new method, doesBucketExist(String bucketName), to help callers determine if a bucket name has been used yet in Amazon S3's global bucket namespace.
Third-Party Dependencies Small upgrade of Apache commons-logging from 1.1 to 1.1.1.
Bug Fixes Fixed a bug in Amazon Simple Notification Service's SignatureChecker utility class.
