872 such indexes are likely to be exploding indexes.
873 - The SDK now supports multiple concurrent transactions.
874 - Datastore stats are now available on a per-namespace basis.
875 - The queue details page in the Admin Console now contains request header
876 details, previous run information, and a task payload viewer.
877 - You can modify the lease on a task leased from a pull queue using the
878 modify_task_lease() method.
879 - Pull Task maximum size has been increased to 1MB.
880 - You can now update the number of available backend instances without needing
881 to first stop the backend using the "backend configure" appcfg.py directive.
882 - You can now set the "References" and "In-Reply-To" headers with the Mail API.
883 http://code.google.com/p/googleappengine/issues/detail?id=2802
884 - The SDK "application" environment variable will now be prefixed with dev~.
885 The new preferred way of retrieving your app id is to use
886 appidentity.get_application_id(). The --default_partition flag can be used
887 for applications whose code relied on a specific environment variable.
888 - In the Deferred API, defer() now accepts the _target parameter.
889 - Added a to_dict() function to db.py which converts a model to a dictionary.
890 - Added a get_original_metadata() method to the Images API to extract EXIF
891 information from images.
892 http://code.google.com/p/googleappengine/issues/detail?id=4133

900 ============================
901 - ProtoRPC is a new experimental library that provides a simple method for
902 creating a well-defined and easy-to-use web-based RPC service.
903 - The development server's datastore implementation now contains logic that
904 closely replicates the consistency guarantees of the High Replication
905 datastore. To use, run the dev_appserver with the flag --high_replication set
907 - All user request have an X-AppEngine-Country header which contains the
908 ISO-3166-1 alpha-2 country code for the user, based on the IP address of the
910 - The Channel API can now provide user presence, this can be configured by
911 adding channel_presence to the list of inbound services for your application.
912 - The Images API now supports the WebP format. Due to limitations in PIL, the
913 SDK does not support the WebP format.
914 - You can switch the timezone for App Engine logs in the Admin Console.
915 http://code.google.com/p/googleappengine/issues/detail?id=734

920 - When displaying corrupt data in the Admin Console dataviewer, a useful error
921 will be displayed, instead of a 500.
922 http://code.google.com/p/googleappengine/issues/detail?id=4945
925 ==============================
926 - Support for Backends which allow developers to create infrastructure
927 components that complement the existing dynamic apps that App Engine already
928 provides. Instances of a backend can maintain state, be addressed
929 individually, and are not subject to per-request time limits. They can also be
930 configured to consume more memory and CPU than ordinary dynamic instances.
931 - Task Queues support pull mode, allowing for more control over task queue work
932 rates. To use pull queues, include the 'mode' argument in your queue.yaml.
933 - Pull queues are supported by a REST API, allowing access from outside App
934 Engine. To use the REST API, you must also include a valid ACL section
935 specifying which users can lease tasks from the pull queue.
936 - Task Queue payload limits have been increased. Queues support 100KB per task.
937 Within App Engine, the new limit is 32 MB per batch of tasks. With the REST
938 API the limit is 1 MB per batch.
939 - HTTP request and response sizes have been increased to 32 MB.
940 - We have removed the rate quotas for requests, datastore operations,
941 memcache operations, and image API operations. Resource quotas still apply.
942 - When creating new applications, developers will now see the High Replication
943 Datastore as the default configuration option. Developers that still wish to
944 use the Master/Slave configuration must explicitly choose this option at
945 application creation time.
946 - The Task Queue maximum configurable processing rate has been increased to
948 - We have added two restrictions to the Mail API to improve the reliability
949 of the service for all applications.
950 - Emails must be sent from email accounts managed by Google (either Gmail or
951 a domain signed up for Google Apps).
952 - Reduced the number of free recipients per day from 2000 to 100 for new
954 - All application Owners, as listed in the Admin Console, can download the app's
955 code, unless code download is disabled for the application.
956 - Added db.py support for making calls to the datastore asynchronously.
957 Available functions are get_async(), put_async(), delete_async(),
958 allocate_ids_async(). Call get_result on the return value of asynchronous
959 datastore functions to block on the call.
960 - Metadata queries can now get all namespaces, kinds, and properties in a given
962 - The Testbed API now supports the Channel API.
963 - Users can provide Django settings to be loaded in webapp's django_setup.
964 - Modified Dashboard latency graphs to indicate they only include dynamic
966 - Fixed an issue where metadata queries did not support unicode characters.
967 - Fixed an issue where HTTP headers could contain new line characters.
968 - A warning message is shown when the Python version used to run the SDK is
969 different than the Python version used in production.

1086 - The Admin Console Task Queues page now displays a more accurate estimate of
1087 queue size for queues containing more than 2000 tasks.
1088 - The Prospective Search API (formerly named the Matcher API) is available for
1089 use by all applications. This API is still experimental, so applications will
1090 be limited to a maximum of 1000 subscriptions.
1091 - The Testbed API provides easy configuration of stub libraries for local

1174 configurations: High Replication or Master/Slave.
1175 http://code.google.com/appengine/docs/python/datastore/hr/#Selecting_a_Datastore
1176 - You can set your application's datastore to read-only mode in the Admin
1177 Console. Any writes attempted while the app is set to read-only will throw a
1178 CapabilityDisabledError. This feature can be helpful for migrating or copying
1179 data between two applications.
1180 http://code.google.com/appengine/docs/adminconsole/applicationsettings.html#Disable_Datastore_Writes
1181 - The Datastore Admin tool has been updated to allow copying of one app's
1182 datastore to another. The destination app must have the Remote API enabled.
1183 http://code.google.com/appengine/docs/adminconsole/datastoreadmin.html
1184 - The deadline for offline URL Fetch API requests for Python and Java have been
1185 increased to a maximum of 10 minutes. The default deadline for offline

1192 ================================
1193 - The Always On feature allows applications to pay and keep 3 instances of their
1194 application always running, which can significantly reduce application
1196 - Developers can now enable Warmup Requests. By specifying a handler in an
1197 app's app.yaml, App Engine will attempt to send a Warmup Request to initialize
1198 new instances before a user interacts with it. This can reduce the latency an
1199 end-user sees for initializing your application.
1200 - The Channel API is now available for all users.
1201 - Task Queue has been officially released, and is no longer an experimental
1202 feature. The API import paths that use 'labs' have been deprecated. Task queue
1203 storage will count towards an application's overall storage quota, and will
1204 thus be charged for.
1205 - The deadline for Task Queue and Cron requests has been raised to 10 minutes.
1206 Datastore and API deadlines within those requests remain unchanged.
1207 - For the Task Queue, developers can specify task retry_parameters in their
1209 - Apps that have enabled billing are allowed up to 100 queues with the Task
1211 - Metadata Queries on the datastore for datastore kinds, namespaces, and entity
1212 properties are available.
1213 - URLFetch allowed response size has been increased, up to 32 MB. Request size
1214 is still limited to 1 MB.
1215 - The request and response sizes for the Images API have been increased to
1217 - The total size of Memcache batch operations is increased to 32 MB. The 1 MB
1218 limit on individual Memcache objects still applies.
1219 - The attachment size for outgoing emails has been increased from 1 MB to 10 MB.
1220 The size limit for incoming emails is still 10 MB.
1221 - Size and quantity limits on datastore batch get/put/delete operations have
1222 been removed. Individual entities are still limited to 1 MB, but your app may
1223 batch as many entities together for get/put/delete calls as the overall
1224 datastore deadline will allow for.
1225 - When iterating over query results, the datastore will now asynchronously
1226 prefetch results, reducing latency in many cases by 10-15%.
1227 - The Admin Console Blacklist page lists the top blacklist rejected visitors.
1228 - The automatic image thumbnailing service supports arbitrary crop sizes up to
1230 - Overall average instance latency in the Admin Console is now a weighted
1231 average over QPS per instance.
1232 - The developer who uploaded an app version can download that version's code
1233 using the appcfg.py download_app command. This feature can be disabled on
1234 a per application basis in the admin console, under the 'Permissions' tab.
1235 Once disabled, code download for the application CANNOT be re-enabled.
1236 - Fixed an issue where custom Admin Console pages did not work for Google
1237 Apps for your Domain users.
1238 - In the Python runtime, an instance is killed and restarted when a request
1239 handler hits DeadlineExceededError. This should fix an issue related to
1240 intermittent SystemErrors using Django.
1241 http://code.google.com/p/googleappengine/issues/detail?id=772
1242 - Allow Django initialization to be moved to appengine_config.py to avoid
1243 Django version conflicts when mixing webapp.template with pure Django.
1244 http://code.google.com/p/googleappengine/issues/detail?id=1758
1245 - Fixed an issue with OpenId over SSL.
1246 http://code.google.com/p/googleappengine/issues/detail?id=3393
1247 - Fixed an issue on the dev_appserver where login/logout code didn't work using
1249 http://code.google.com/p/googleappengine/issues/detail?id=3566
1250 - Fixed an issue in the dev_appserver where get_serving_url did not work
1251 for transparent, cropped PNGs:
1252 http://code.google.com/p/googleappengine/issues/detail?id=3887
1253 - Fixed an issue with the DatastoreFileStub.
1254 http://code.google.com/p/googleappengine/issues/detail?id=3895
1257 ==================================
1258 - Builtin app.yaml handlers are available for common application functions,
1260 http://code.google.com/appengine/docs/python/config/appconfig.html#Builtin_Handlers
1261 - The Admin Console now provides an experimental tool to delete all entities in
1262 the datastore or all entities of a given type. This is available only if
1263 enabled using the datastore_admin builtin. Deleting entities will count
1264 against application quota.
1265 http://code.google.com/appengine/docs/python/datastore/creatinggettinganddeletingdata.html#Deleting_Entities_in_Bulk
1266 - You can run task queue tasks immediately from the Admin Console.
1267 - You can now specify the quality of JPEG images via the Image API's
1268 execute_transforms function. Available in production only.
1269 - Support for login of multiple Google accounts within an app, and longer login
1270 sessions. For more information see:
1271 http://www.google.com/support/accounts/bin/answer.py?answer=181599
1272 - In queue.yaml, the maximum allowed bucket size is now 100.
1273 - Precompilation is now enabled by default. To disable, use the
1274 --no_precompilation flag when updating your app.
1275 - BlobInfo now has an open() method that returns a BlobReader.
1276 - BlobReader now accepts a BlobInfo.
1277 - Removed limits on zigzag merge-join queries. Therefore the error "The built-in
1278 indices are not efficient enough for this query and your data. Please add a
1279 composite index for this query." will no longer be thrown in most cases,
1280 enabling more types of queries without indexes.
1281 - Fixed an issue with task queue tasks not running on the dev_appserver when
1283 - Fixed an issue on the dev_appserver where auto task running wasn't working for
1285 - Fixed an issue reserving App Ids by owners of similarly-named mails accounts
1286 containing periods, multiple cases, and googlemail.com address.
