• New and improved Iterators. Users always had problems traversing paginated collections, sometimes having to construct nested loops. Now, everything is offered in an easy-to-use manner that harnesses the power of PHP's native interfaces. For more information, please consult the documentation for this new feature.
• Tenant names and tenant IDs added to OpenStack authentication. Users can now authenticate more specifically. Also fixes an issue one customer had regarding empty Service Catalogs.
• Greater use of Symfony's EventDispatcher. The decision was made to rely more on event dispatching, rather than inheritance, to provide additional features. One of the immediate benefits of this is that there is less repetition in the Request and Response classes.
• Uploading single objects to CloudFiles uses less bandwidth. Previously, when a single object was uploaded, another request was executed afterwards to populate the new object. This was relatively expensive operation - especially for large files. Now we populate the new object using information provided in the response for the PUT operation.
• Fix to BulkExtract content-type uploads. Now the API is allowed to type guess the archived files in a tarball. Previously, they were manually set to application/json.
• Better documentation for authentication, cloud monitoring, queues and iterators.
• More consistent use of mock objects in unit tests. We are now using the MockPlugin for Guzzle to create FIFO request queues.
