This release updates to the latest AWS SDK. We also now support and test against the lowest set of available PHP library dependencies. There are no Drupal-specific changes in this release since the 7.x-2.0-beta3 release.
Changes since 7.x-2.0-beta3:
Update to the AWS SDK 2.8.5 and test lowest requirements.
This is a major update that uses the AWS PHP SDK v2. Upgrades from the 7.x-1.x branch are supported. This module now uses Composer Manager to automatically import the upstream library, so once the upgrade is complete the old awssdk module and library can be removed. Custom code and other modules will need to be upgraded to work with our new command hooks and the new S3 SDK itself.
Image style support has been completely rewritten, at the cost of a very small required patch to Drupal's image module. See the README for the details.
