4 App Engine Java SDK - Release Notes
8 - We are pleased to announce the availability of Dedicated Memcache service
9 to our customers in the EU.
13 - The Performance Settings section of the Application settings page in the
14 Admin Console, Backends API and all backends related management tools are now
15 deprecated and will be removed in a future release. Users of Backends are
16 recommended to migrate to the App Engine Modules API, which provides a more
17 flexible implementation of the same functionality. These settings are now all
18 configurable via Modules configuration files.
19 See the Modules documentation for more information:
20 https://developers.google.com/appengine/docs/java/modules/#Java_Configuration
24 - Java 6 applications cannot be deployed to Google App Engine from any version
25 of the SDK. Existing Java 6 applications will continue to run. If you are
26 still relying on a Java 6 application in Google App Engine, we strongly
27 encourage you to start testing and deploying your app using Java 7. Java 7
28 has been certified by Oracle to be fully backwards compatible with Java 6,
29 as well as providing a number of benefits to developers. Java 7 applications
30 will be fully supported in future releases of the App Engine SDK.
31 If you absolutely need to continue to deploy Java 6 applications for
32 compatibility reasons, you can request that your application be whitelisted
33 for Java 6 deployment from http://goo.gl/ycffXq. As we review each whitelist
34 application by hand, please allow 10 working days for review, and note that
35 only billed applications that show a proven incompatibility will be
36 considered for exemption.
37 - Newly created App Engine applications now have a Google Cloud Storage bucket
38 created automatically as part of the same Google Cloud Project. For more

399 ListIndexesException, ListIndexesRequest, ListIndexesResponse, ListRequest,
400 ListResponse, and RemoveException were removed from the Search API in the
401 SDK. If your app references any of these classes, you must deploy a new
402 version without these references before the next release of App Engine.
403 If you do not do this, your app may stop working in production.
404 - The Conversion API, which was decommissioned last release, has been removed
405 from the SDK. In a future release, the API will be removed from the
406 runtime and applications that attempt to use it may stop working.

1172 - Fixed a bug that caused appengine-jsr107cache-1.5.0.jar to be empty.
1176 - Support for Backends which allow developers to create infrastructure
1177 components that complement the existing dynamic apps that App Engine already
1178 provides. Instances of a backend can maintain state, be addressed
1179 individually, and are not subject to per-request time limits. They can also be
1180 configured to consume more memory and CPU than ordinary dynamic instances.
1181 - Task Queues support pull mode, allowing for more control over task queue work
1182 rates. To use pull queues, include the 'mode' element in your queue.xml.
1183 - Pull queues are supported by a REST API, allowing access from outside App
1184 Engine. To use the REST API, you must also include a valid ACL section
1185 specifying which users can lease tasks from the pull queue.
1186 - Task Queue payload limits have been increased. Queues support 100KB per task.
1187 Within App Engine, the new limit is 32 MB per batch of tasks. With the REST

1189 - HTTP request and response sizes have been increased to 32 MB.
1190 - We have removed the rate quotas for requests, datastore operations,
1191 memcache operations, and image API operations. Resource quotas still apply.
1192 - When creating new applications, developers will now see the High Replication
1193 Datastore as the default configuration option. Developers that still wish to
1194 use the Master/Slave configuration must explicitly choose this option at
1195 application creation time.
1196 - The Task Queue maximum configurable processing rate has been increased to
1198 - Modified Dashboard latency graphs to indicate they only include dynamic

1337 - The Always On feature allows applications to pay and keep 3 instances of their
1338 application always running, which can significantly reduce application
1340 - Developers can now enable Warmup Requests. By specifying a handler in an
1341 app's appengine-web.xml, App Engine will attempt to send a Warmup Request to
1342 initialize new instances before a user interacts with it. This can reduce the
1343 latency an end-user sees for initializing your application.
1344 - The Channel API is now available for all users.
1345 - Task Queue has been officially released, and is no longer an experimental
1346 feature. The API import paths that use 'labs' have been deprecated. Task queue
1347 storage will count towards an application's overall storage quota, and will
1348 thus be charged for.
1349 - The deadline for Task Queue and Cron requests has been raised to 10 minutes.
1350 Datastore and API deadlines within those requests remain unchanged.
1351 - For the Task Queue, developers can specify task retry-parameters in their

1362 limit on individual Memcache objects still applies.
1363 - The attachment size for outgoing emails has been increased from 1 MB to 10 MB.
1364 The size limit for incoming emails is still 10 MB.
1365 - Size and quantity limits on datastore batch get/put/delete operations have
1366 been removed. Individual entities are still limited to 1 MB, but your app may
1367 batch as many entities together for get/put/delete calls as the overall
1368 datastore deadline will allow for.
1369 - When iterating over query results, the datastore will now asynchronously
1370 prefetch results, reducing latency in many cases by 10-15%.
1371 - The Admin Console Blacklist page lists the top blacklist rejected visitors.
1372 - The automatic image thumbnailing service supports arbitrary crop sizes up to
1374 - Overall average instance latency in the Admin Console is now a weighted
1375 average over QPS per instance.
1376 - Added a low-level AysncDatastoreService for making calls to the datastore
1378 - Added a getBodyAsBytes() method to QueueStateInfo.TaskStateInfo, this returns
1379 the body of the task state as a pure byte-string.
1380 - The whitelist has been updated to include all classes from javax.xml.soap.
1381 - Fixed an issue sending email to multiple recipients.
1382 http://code.google.com/p/googleappengine/issues/detail?id=1623

1391 - Added an OutputSettings class to the Images API to specify the JPEG encoding
1392 quality when running in production.
1393 - Support for login of multiple Google accounts within an app, and longer login
1394 sessions. For more information see:
1395 http://www.google.com/support/accounts/bin/answer.py?answer=181599
1396 - In queue.xml, the maximum allowed bucket size is now 100.
1397 - Removed limits on zigzag merge-join queries. Therefore the error "The built-in
1398 indices are not efficient enough for this query and your data. Please add a
1399 composite index for this query." will no longer be thrown in most cases,
1400 enabling more types of queries without indexes.
1401 - The whitelist has been updated to include java.net.InetAddress and some
1402 interfaces and abstract classes in javax.xml.soap, including
1403 javax.xml.soap.SOAPMessage.
1404 - Fixed an issue reserving App Ids by owners of emails containing periods,
1405 multiple cases, and googlemail.com address.
1406 http://code.google.com/p/googleappengine/issues/detail?id=1196
