133 usage by indexes using the documented property type names ("Integer",
135 https://developers.google.com/appengine/docs/python/datastore/stats)

280 - In the Images API, the getServingUrl() call now optionally allows you to
281 specify if the URL you are generating should be served over https.

299 https://developers.google.com/appengine/docs/java/runtime#Request_Headers
300 - As announced in 1.6.4, omitting the <threadsafe> directive from

363 an app adminstrator, including when that email is sent from a cron job or task
365 - In the Admin Console, you can now choose how much and how long you'd like to
366 store logs. All apps get 1G for free and eventually will be able to pay for

395 application quota, including Instance Hours, Datastore Ops and Datastore
397 - Developers can now specify how long a channel token will last until it
398 expires, with the default remaining two hours. Channel API quota is now
399 measured both in calls to create a channel and the number of hours of channel

401 creation calls * 2, so free apps get 200 hours of requested channel token
403 - Task Queue API requests now include a X-Appengine-TaskETA header, that can be
404 used to measure task delivery latency.
405 - We have removed the deprecated labs version of the TaskQueue API.

415 - Fixed an issue with the Images API where valid images were returning a
417 http://code.google.com/p/googleappengine/issues/detail?id=5545
421 - You can now configure Frontend Instance Classes from your Admin Console's
422 application settings page. Three classes are available, with increasing

424 basic frontend instance setting of 128MB memory and 600MHz CPU.
425 - We've added new functionality to the Log API that will allow you to read your
426 application's logs programmatically.

453 paid apps are now covered by our SLA.
454 http://code.google.com/appengine/docs/billing.html
455 - Paid apps can now specify the maximum pending latency for instances and the
456 minimum number of idle instances for your application in the Admin Console.
457 - Task Queue storage has been separated in to its own line item. Previously,
458 this was included in Datastore storage.
459 - We have released an experimental utility, available in the Admin Console, to
460 assist in migrating your application to the High Replication datastore. This
461 utility allows you to copy the bulk of your data in the background, while the

542 DatastoreNeedIndexException, many will now succeed. A small percentage will
544 - The SDK datastore viewer in the dev console now displays the number of "Write
545 Ops" for each entity. "Write Ops" are the total number of entity and index
546 writes that were required to create the entity.
547 - The Prospective Search API is available in Java for all applications. This API

587 - Added an improved HRD migration tool that requires a read-only period relative
588 to your datastore write rate (as opposed to your datastore size, which is how
589 the current version behaves). The tool is not yet generally available. If you
590 are interested in being an early adopter please fill out this form:

604 http://code.google.com/appengine/docs/python/datastore/queries.html#Big_Entities_and_Exploding_Indexes

618 - When the SDK throws a DatastoreNeedIndexException for a missing index
619 definition, the exception can now be caught.
623 - The development server's datastore and testing service implementations now
624 contains logic that closely replicates the consistency guarantees of the High
625 Replication datastore. To use, run the dev_appserver with the flag
626 -Ddatastore.default_high_rep_job_policy_unapplied_job_pct=20.
627 - All user request have an X-AppEngine-Country header which contains the
628 ISO-3166-1 alpha-2 country code for the user, based on the IP address of the

667 - Fixed a bug that caused appengine-jsr107cache-1.5.0.jar to be empty.
671 - Support for Backends which allow developers to create infrastructure
672 components that complement the existing dynamic apps that App Engine already
673 provides. Instances of a backend can maintain state, be addressed
674 individually, and are not subject to per-request time limits. They can also be
675 configured to consume more memory and CPU than ordinary dynamic instances.
676 - Task Queues support pull mode, allowing for more control over task queue work
677 rates. To use pull queues, include the 'mode' element in your queue.xml.
678 - Pull queues are supported by a REST API, allowing access from outside App
679 Engine. To use the REST API, you must also include a valid ACL section
680 specifying which users can lease tasks from the pull queue.
681 - Task Queue payload limits have been increased. Queues support 100KB per task.
682 Within App Engine, the new limit is 32 MB per batch of tasks. With the REST
683 API the limit is 1 MB per batch.
684 - HTTP request and response sizes have been increased to 32 MB.
685 - We have removed the rate quotas for requests, datastore operations,
686 memcache operations, and image API operations. Resource quotas still apply.
687 - When creating new applications, developers will now see the High Replication
688 Datastore as the default configuration option. Developers that still wish to
689 use the Master/Slave configuration must explicitly choose this option at
690 application creation time.
691 - The Task Queue maximum configurable processing rate has been increased to
693 - Modified Dashboard latency graphs to indicate they only include dynamic
695 - We have added two restrictions to the Mail API to improve the reliability
696 of the service for all applications.

759 - Java applications can enable concurrent request support by setting
760 <threadsafe> to True in their appengine-web.xml. This flag indicates that

762 may safely run at the same time in the same memory space for your application.
763 - Deferred library support now available in Java.
764 http://code.google.com/p/googleappengine/issues/detail?id=2381

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

859 The size limit for incoming emails is still 10 MB.
860 - Size and quantity limits on datastore batch get/put/delete operations have

862 batch as many entities together for get/put/delete calls as the overall
863 datastore deadline will allow for.
864 - When iterating over query results, the datastore will now asynchronously
865 prefetch results, reducing latency in many cases by 10-15%.

891 - In queue.xml, the maximum allowed bucket size is now 100.
892 - Removed limits on zigzag merge-join queries. Therefore the error "The built-in
893 indices are not efficient enough for this query and your data. Please add a
894 composite index for this query." will no longer be thrown in most cases,
895 enabling more types of queries without indexes.
896 - The whitelist has been updated to include java.net.InetAddress and some
897 interfaces and abstract classes in javax.xml.soap, including
898 javax.xml.soap.SOAPMessage.
899 - Fixed an issue reserving App Ids by owners of emails containing periods,
900 multiple cases, and googlemail.com address.

920 - Users can now serve custom static error pages for over_quota, dos_api_denial
922 - Results of datastore count() queries and offsets for all datastore queries
923 are no longer capped at 1000.
