120 - We are pleased to announce the availability of Dedicated Memcache service
121 to our customers in the EU.
125 - The Performance Settings section of the Application settings page in the
126 Admin Console, Backends API and all backends related management tools are now
127 deprecated and will be removed in a future release. Users of Backends are
128 recommended to migrate to the App Engine Modules API, which provides a more
129 flexible implementation of the same functionality. These settings are now all
130 configurable via Modules configuration files.
131 See the Modules documentation for more information:
132 https://developers.google.com/appengine/docs/java/modules/#Java_Configuration
136 - Java 6 applications cannot be deployed to Google App Engine from any version
137 of the SDK. Existing Java 6 applications will continue to run. If you are
138 still relying on a Java 6 application in Google App Engine, we strongly
139 encourage you to start testing and deploying your app using Java 7. Java 7
140 has been certified by Oracle to be fully backwards compatible with Java 6,
141 as well as providing a number of benefits to developers. Java 7 applications
142 will be fully supported in future releases of the App Engine SDK.
143 If you absolutely need to continue to deploy Java 6 applications for
144 compatibility reasons, you can request that your application be whitelisted
145 for Java 6 deployment from http://goo.gl/ycffXq. As we review each whitelist
146 application by hand, please allow 10 working days for review, and note that
147 only billed applications that show a proven incompatibility will be
148 considered for exemption.
149 - Newly created App Engine applications now have a Google Cloud Storage bucket
150 created automatically as part of the same Google Cloud Project. For more

393 billing enabled can exceed the free quota levels and will be charged for
394 usage above these levels.
395 - Estimated number of search results will only be accurate if it is less than
396 or equal to the number of results requested. By default this can be
397 overridden by setting number_found_accuracy QueryOption in the Search API.

453 runtime, please use the --use_java6 flag when deploying your app. We encourage
454 you to move to Java7 as soon as possible.
455 - Billing enabled apps will no longer be subject to a $2.10 minimum weekly
456 spend. Instead, apps will only be charged for their actual usage.
457 - Fixed an issue where Datastore auto ids assigned by the scattered id
458 policy were too large to be represented as floating point numbers in the SDK.
459 - Fixed an issue with sort by doc_id not translating correctly causing
460 InvalidRequest errors in the Search API
461 https://code.google.com/p/googleappengine/issues/detail?id=8958
465 - Improvements to the App Engine billing system will be rolled out gradually to
467 - The application summary no longer displays the default version of a running

484 not currently enforced, but will be part of the pricing model for the Search
485 API in a future release.
486 - The experimental Search API's ability to explicitly sort search results by
487 SortExpression.RANK_FIELD_NAME (i.e. _order_id) field in ascending order has
489 - Globally consistent indexes in the experimental Search API are now deprecated
490 and will be removed in the next release.
491 - Task Queue tasks may now be added and deleted asynchronously. This allows
492 applications to perform common task queue operations without blocking. This is

510 - The deprecated classes AddException, AddResponse, ListException,
511 ListIndexesException, ListIndexesRequest, ListIndexesResponse, ListRequest,
512 ListResponse, and RemoveException were removed from the Search API in the
513 SDK. If your app references any of these classes, you must deploy a new
514 version without these references before the next release of App Engine.
515 If you do not do this, your app may stop working in production.
516 - The Conversion API, which was decommissioned last release, has been removed
517 from the SDK. In a future release, the API will be removed from the
518 runtime and applications that attempt to use it may stop working.

1014 - Developers can now specify how long a channel token will last until it
1015 expires, with the default remaining two hours. Channel API quota is now
1016 measured both in calls to create a channel and the number of hours of channel
1017 time requested. The maximum hours of quota is the maximum number of channel
1018 creation calls * 2, so free apps get 200 hours of requested channel token

1075 this was included in Datastore storage.
1076 - We have released an experimental utility, available in the Admin Console, to
1077 assist in migrating your application to the High Replication datastore. This
1078 utility allows you to copy the bulk of your data in the background, while the

1156 BlobstoreService.createUploadUrl().
1157 - Zigzag merge join queries will now continue scanning up to the 30 second
1158 Datastore query deadline. For zigzag queries that used to generate
1159 DatastoreNeedIndexException, many will now succeed. A small percentage will
1160 now instead timeout.
1161 - The SDK datastore viewer in the dev console now displays the number of "Write
1162 Ops" for each entity. "Write Ops" are the total number of entity and index
1163 writes that were required to create the entity.
1164 - The Prospective Search API is available in Java for all applications. This API
1165 is still experimental, so applications will be limited to a maximum of 1000

1441 http://code.google.com/p/googleappengine/issues/detail?id=4216
1445 There were no updates to the Java SDK for the 1.4.1 App Engine release.
1449 - The Always On feature allows applications to pay and keep 3 instances of their
1450 application always running, which can significantly reduce application
1452 - Developers can now enable Warmup Requests. By specifying a handler in an
1453 app's appengine-web.xml, App Engine will attempt to send a Warmup Request to
1454 initialize new instances before a user interacts with it. This can reduce the
1455 latency an end-user sees for initializing your application.
1456 - The Channel API is now available for all users.
1457 - Task Queue has been officially released, and is no longer an experimental
1458 feature. The API import paths that use 'labs' have been deprecated. Task queue
1459 storage will count towards an application's overall storage quota, and will
1460 thus be charged for.
1461 - The deadline for Task Queue and Cron requests has been raised to 10 minutes.
1462 Datastore and API deadlines within those requests remain unchanged.

1465 - Apps that have enabled billing are allowed up to 100 queues with the Task
1467 - Metadata Queries on the datastore for datastore kinds, namespaces, and entity
1468 properties are available.

1470 is still limited to 1 MB.
1471 - The request and response sizes for the Images API have been increased to
1473 - The total size of Memcache batch operations is increased to 32 MB. The 1 MB
1474 limit on individual Memcache objects still applies.
1475 - The attachment size for outgoing emails has been increased from 1 MB to 10 MB.
1476 The size limit for incoming emails is still 10 MB.
1477 - Size and quantity limits on datastore batch get/put/delete operations have
1478 been removed. Individual entities are still limited to 1 MB, but your app may
1479 batch as many entities together for get/put/delete calls as the overall
1480 datastore deadline will allow for.
1481 - When iterating over query results, the datastore will now asynchronously
1482 prefetch results, reducing latency in many cases by 10-15%.
1483 - The Admin Console Blacklist page lists the top blacklist rejected visitors.
1484 - The automatic image thumbnailing service supports arbitrary crop sizes up to
1486 - Overall average instance latency in the Admin Console is now a weighted
1487 average over QPS per instance.
1488 - Added a low-level AysncDatastoreService for making calls to the datastore
1490 - Added a getBodyAsBytes() method to QueueStateInfo.TaskStateInfo, this returns
1491 the body of the task state as a pure byte-string.

1508 - In queue.xml, the maximum allowed bucket size is now 100.
1509 - Removed limits on zigzag merge-join queries. Therefore the error "The built-in
1510 indices are not efficient enough for this query and your data. Please add a
1511 composite index for this query." will no longer be thrown in most cases,
1512 enabling more types of queries without indexes.
1513 - The whitelist has been updated to include java.net.InetAddress and some
1514 interfaces and abstract classes in javax.xml.soap, including
1515 javax.xml.soap.SOAPMessage.
