91 ===============================
92 - Billed applications that have specified additional logs retention over 1 GB
93 are now being charged for that storage at $0.24/GB/month (the first gigabyte

142 traffic is split by either cookie or IP address.
143 - Emails that are sent from Google Apps domains email addresses where the domain
144 has been set up to use DKIM will be signed: when an email was from a request
145 that originated on that app's domain or any time the email was sent from
146 an app adminstrator, including when that email is sent from a cron job or task
148 - In the Admin Console, you can now choose how much and how long you'd like to
149 store logs. All apps get 1G for free and eventually will be able to pay for
150 more, while the amount can be increased this release we won't start charging
151 for the additional capacity until the next release at the earliest.
152 - The instances screen in the Admin Console now has a button to shut down
154 - Each application log has a link to the instance that served the request. If
155 the instance is no longer serving requests, a message will be displayed.

193 application quota, including Instance Hours, Datastore Ops and Datastore
195 - Developers can now specify how long a channel token will last until it
196 expires, with the default remaining two hours. Channel API quota is now
197 measured both in calls to create a channel and the number of hours of channel
198 time requested. The maximum hours of quota is the maximum number of channel
199 creation calls * 2, so free apps get 200 hours of requested channel token
201 - Python Django now work with Cloud SQL without additional configuration. For
202 further information see https://developers.google.com/cloud-sql/.
203 - Task Queue API requests now include a X-Appengine-TaskETA header, that can be

452 to your datastore write rate (as opposed to your datastore size, which is how
453 the current version behaves). The tool is not yet generally available. If you
454 are interested in being an early adopter please fill out this form:
456 - Fixed an issue in the Channel API where jsapi was not served with the correct
458 - Fixed an issue that broke use_library when the Python SDK was located in a
459 directory that contained the word 'django'.
460 - Fixed an issue where blobs could not be uploaded using HTTPS.
461 - Fixed an issue where GQL didn't allow querying for valid kind names
462 containing '.', '-', and ':' by supporting quoted identifiers.
463 http://code.google.com/p/googleappengine/issues/detail?id=2584
466 =============================
467 - You can now specify the minimum pending latency for instances and the maximum
468 number of idle instances for your application in the Admin Console.
469 - The datastore now never requires an exploding index.
470 http://code.google.com/appengine/docs/python/datastore/queries.html#Big_Entities_and_Exploding_Indexes
471 - The SDK will now never suggest indexes with the same property repeated, as
472 such indexes are likely to be exploding indexes.
473 - The SDK now supports multiple concurrent transactions.
474 - Datastore stats are now available on a per-namespace basis.
475 - The queue details page in the Admin Console now contains request header
476 details, previous run information, and a task payload viewer.
477 - You can modify the lease on a task leased from a pull queue using the
478 modify_task_lease() method.
479 - Pull Task maximum size has been increased to 1MB.
480 - You can now update the number of available backend instances without needing
481 to first stop the backend using the "backend configure" appcfg.py directive.
482 - You can now set the "References" and "In-Reply-To" headers with the Mail API.
483 http://code.google.com/p/googleappengine/issues/detail?id=2802
484 - The SDK "application" environment variable will now be prefixed with dev~.
485 The new preferred way of retrieving your app id is to use
486 appidentity.get_application_id(). The --default_partition flag can be used
487 for applications whose code relied on a specific environment variable.
488 - In the Deferred API, defer() now accepts the _target parameter.
489 - Added a to_dict() function to db.py which converts a model to a dictionary.
490 - Added a get_original_metadata() method to the Images API to extract EXIF
491 information from images.
492 http://code.google.com/p/googleappengine/issues/detail?id=4133

500 ============================
501 - ProtoRPC is a new experimental library that provides a simple method for
502 creating a well-defined and easy-to-use web-based RPC service.
503 - The development server's datastore implementation now contains logic that
504 closely replicates the consistency guarantees of the High Replication
505 datastore. To use, run the dev_appserver with the flag --high_replication set
507 - All user request have an X-AppEngine-Country header which contains the
508 ISO-3166-1 alpha-2 country code for the user, based on the IP address of the
510 - The Channel API can now provide user presence, this can be configured by
511 adding channel_presence to the list of inbound services for your application.

525 ==============================
526 - Support for Backends which allow developers to create infrastructure
527 components that complement the existing dynamic apps that App Engine already
528 provides. Instances of a backend can maintain state, be addressed
529 individually, and are not subject to per-request time limits. They can also be
530 configured to consume more memory and CPU than ordinary dynamic instances.
531 - Task Queues support pull mode, allowing for more control over task queue work
532 rates. To use pull queues, include the 'mode' argument in your queue.yaml.
533 - Pull queues are supported by a REST API, allowing access from outside App
534 Engine. To use the REST API, you must also include a valid ACL section
535 specifying which users can lease tasks from the pull queue.
536 - Task Queue payload limits have been increased. Queues support 100KB per task.
537 Within App Engine, the new limit is 32 MB per batch of tasks. With the REST
538 API the limit is 1 MB per batch.
539 - HTTP request and response sizes have been increased to 32 MB.
540 - We have removed the rate quotas for requests, datastore operations,
541 memcache operations, and image API operations. Resource quotas still apply.
542 - When creating new applications, developers will now see the High Replication
543 Datastore as the default configuration option. Developers that still wish to
544 use the Master/Slave configuration must explicitly choose this option at
545 application creation time.
546 - The Task Queue maximum configurable processing rate has been increased to
548 - We have added two restrictions to the Mail API to improve the reliability
549 of the service for all applications.
550 - Emails must be sent from email accounts managed by Google (either Gmail or
551 a domain signed up for Google Apps).
552 - Reduced the number of free recipients per day from 2000 to 100 for new
554 - All application Owners, as listed in the Admin Console, can download the app's
555 code, unless code download is disabled for the application.
556 - Added db.py support for making calls to the datastore asynchronously.
557 Available functions are get_async(), put_async(), delete_async(),
558 allocate_ids_async(). Call get_result on the return value of asynchronous
559 datastore functions to block on the call.
560 - Metadata queries can now get all namespaces, kinds, and properties in a given
562 - The Testbed API now supports the Channel API.
563 - Users can provide Django settings to be loaded in webapp's django_setup.
564 - Modified Dashboard latency graphs to indicate they only include dynamic
566 - Fixed an issue where metadata queries did not support unicode characters.
567 - Fixed an issue where HTTP headers could contain new line characters.
568 - A warning message is shown when the Python version used to run the SDK is
569 different than the Python version used in production.

774 configurations: High Replication or Master/Slave.
775 http://code.google.com/appengine/docs/python/datastore/hr/#Selecting_a_Datastore
776 - You can set your application's datastore to read-only mode in the Admin
777 Console. Any writes attempted while the app is set to read-only will throw a
778 CapabilityDisabledError. This feature can be helpful for migrating or copying
779 data between two applications.
780 http://code.google.com/appengine/docs/adminconsole/applicationsettings.html#Disable_Datastore_Writes
781 - The Datastore Admin tool has been updated to allow copying of one app's

794 application always running, which can significantly reduce application
796 - Developers can now enable Warmup Requests. By specifying a handler in an
797 app's app.yaml, App Engine will attempt to send a Warmup Request to initialize
798 new instances before a user interacts with it. This can reduce the latency an
799 end-user sees for initializing your application.
800 - The Channel API is now available for all users.
801 - Task Queue has been officially released, and is no longer an experimental
802 feature. The API import paths that use 'labs' have been deprecated. Task queue
803 storage will count towards an application's overall storage quota, and will
805 - The deadline for Task Queue and Cron requests has been raised to 10 minutes.
806 Datastore and API deadlines within those requests remain unchanged.
807 - For the Task Queue, developers can specify task retry_parameters in their
809 - Apps that have enabled billing are allowed up to 100 queues with the Task
811 - Metadata Queries on the datastore for datastore kinds, namespaces, and entity
812 properties are available.
813 - URLFetch allowed response size has been increased, up to 32 MB. Request size
814 is still limited to 1 MB.
815 - The request and response sizes for the Images API have been increased to
817 - The total size of Memcache batch operations is increased to 32 MB. The 1 MB
818 limit on individual Memcache objects still applies.
819 - The attachment size for outgoing emails has been increased from 1 MB to 10 MB.
820 The size limit for incoming emails is still 10 MB.
821 - Size and quantity limits on datastore batch get/put/delete operations have
822 been removed. Individual entities are still limited to 1 MB, but your app may
823 batch as many entities together for get/put/delete calls as the overall
824 datastore deadline will allow for.
825 - When iterating over query results, the datastore will now asynchronously
826 prefetch results, reducing latency in many cases by 10-15%.
827 - The Admin Console Blacklist page lists the top blacklist rejected visitors.
828 - The automatic image thumbnailing service supports arbitrary crop sizes up to
830 - Overall average instance latency in the Admin Console is now a weighted
831 average over QPS per instance.
832 - The developer who uploaded an app version can download that version's code
833 using the appcfg.py download_app command. This feature can be disabled on
834 a per application basis in the admin console, under the 'Permissions' tab.
835 Once disabled, code download for the application CANNOT be re-enabled.
836 - Fixed an issue where custom Admin Console pages did not work for Google
837 Apps for your Domain users.
838 - In the Python runtime, an instance is killed and restarted when a request
839 handler hits DeadlineExceededError. This should fix an issue related to
840 intermittent SystemErrors using Django.
841 http://code.google.com/p/googleappengine/issues/detail?id=772
842 - Allow Django initialization to be moved to appengine_config.py to avoid

858 - Builtin app.yaml handlers are available for common application functions,
860 http://code.google.com/appengine/docs/python/config/appconfig.html#Builtin_Handlers
861 - The Admin Console now provides an experimental tool to delete all entities in
862 the datastore or all entities of a given type. This is available only if
863 enabled using the datastore_admin builtin. Deleting entities will count
864 against application quota.
865 http://code.google.com/appengine/docs/python/datastore/creatinggettinganddeletingdata.html#Deleting_Entities_in_Bulk
866 - You can run task queue tasks immediately from the Admin Console.
867 - You can now specify the quality of JPEG images via the Image API's
868 execute_transforms function. Available in production only.

872 - In queue.yaml, the maximum allowed bucket size is now 100.
873 - Precompilation is now enabled by default. To disable, use the
874 --no_precompilation flag when updating your app.
875 - BlobInfo now has an open() method that returns a BlobReader.
876 - BlobReader now accepts a BlobInfo.
877 - Removed limits on zigzag merge-join queries. Therefore the error "The built-in
878 indices are not efficient enough for this query and your data. Please add a
879 composite index for this query." will no longer be thrown in most cases,
880 enabling more types of queries without indexes.
