Release: AWS SDK for PHP 2.0.1

Amazon S3 - Archiving Objects to Amazon Glacier

Amazon S3 now provides a storage option that enables you to utilize Amazon Glacier's low-cost storage service for data archival. To archive objects, you define archival rules identifying objects and a timeline when you want Amazon S3 to archive these objects to Amazon Glacier. You can easily set the rules on a bucket using the Amazon S3 management console or programmatically using the SDK.

Amazon DynamoDB - Consistent Reads for BatchWriteItem

By default, read operations performed by the BatchGetItem API are eventually consistent. A new ConsistentRead parameter in BatchGetItem lets you choose read consistency instead, for any tables in the request.

Amazon DynamoDB - CRC32 Checksum Support

Amazon DynamoDB calculates a CRC32 checksum of the HTTP payload of the response and returns this checksum in a new header, x-amz-crc32. An application program should compute its own CRC32 checksum and compare it with the x-amz-crc32 header; if the checksums do not match, it might indicate that the data was corrupted in transit. If this happens, the program should retry the request. Note: SDK users do not need to manually perform this verification, because the SDK computes the checksum of each response from Amazon DynamoDB and automatically retries the request if a mismatch is detected.

New Asia Pacific (Sydney) Region

Support for the new Asia Pacific (Sydney) Region has been added.
