590 - The SDK datastore viewer in the dev console now displays the number of "Write
591 Ops" for each entity. "Write Ops" are the total number of entity and index
592 writes that were required to create the entity.
593 - The Prospective Search API is available in Java for all applications. This API
594 is still experimental, so applications will be limited to a maximum of 1000

717 - Support for Backends which allow developers to create infrastructure
718 components that complement the existing dynamic apps that App Engine already
719 provides. Instances of a backend can maintain state, be addressed
720 individually, and are not subject to per-request time limits. They can also be
721 configured to consume more memory and CPU than ordinary dynamic instances.
722 - Task Queues support pull mode, allowing for more control over task queue work
723 rates. To use pull queues, include the 'mode' element in your queue.xml.

730 - HTTP request and response sizes have been increased to 32 MB.
731 - We have removed the rate quotas for requests, datastore operations,
732 memcache operations, and image API operations. Resource quotas still apply.
733 - When creating new applications, developers will now see the High Replication
734 Datastore as the default configuration option. Developers that still wish to
735 use the Master/Slave configuration must explicitly choose this option at
736 application creation time.
737 - The Task Queue maximum configurable processing rate has been increased to
739 - Modified Dashboard latency graphs to indicate they only include dynamic

878 - The Always On feature allows applications to pay and keep 3 instances of their
879 application always running, which can significantly reduce application
881 - Developers can now enable Warmup Requests. By specifying a handler in an
882 app's appengine-web.xml, App Engine will attempt to send a Warmup Request to
883 initialize new instances before a user interacts with it. This can reduce the
884 latency an end-user sees for initializing your application.
885 - The Channel API is now available for all users.
886 - Task Queue has been officially released, and is no longer an experimental
887 feature. The API import paths that use 'labs' have been deprecated. Task queue
