117 - The Performance Settings section of the Application settings page in the
118 Admin Console, Backends API and all backends related management tools are now
119 deprecated and will be removed in a future release. Users of Backends are
120 recommended to migrate to the App Engine Modules API, which provides a more
121 flexible implementation of the same functionality. These settings are now all
122 configurable via Modules configuration files.

124 https://developers.google.com/appengine/docs/java/modules/#Java_Configuration
128 - Java 6 applications cannot be deployed to Google App Engine from any version
129 of the SDK. Existing Java 6 applications will continue to run. If you are
130 still relying on a Java 6 application in Google App Engine, we strongly
131 encourage you to start testing and deploying your app using Java 7. Java 7
132 has been certified by Oracle to be fully backwards compatible with Java 6,
133 as well as providing a number of benefits to developers. Java 7 applications
134 will be fully supported in future releases of the App Engine SDK.
135 If you absolutely need to continue to deploy Java 6 applications for
136 compatibility reasons, you can request that your application be whitelisted
137 for Java 6 deployment from http://goo.gl/ycffXq. As we review each whitelist
138 application by hand, please allow 10 working days for review, and note that
139 only billed applications that show a proven incompatibility will be
140 considered for exemption.

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

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

1006 - Developers can now specify how long a channel token will last until it
1007 expires, with the default remaining two hours. Channel API quota is now
1008 measured both in calls to create a channel and the number of hours of channel
1009 time requested. The maximum hours of quota is the maximum number of channel
1010 creation calls * 2, so free apps get 200 hours of requested channel token

1067 this was included in Datastore storage.
1068 - We have released an experimental utility, available in the Admin Console, to
1069 assist in migrating your application to the High Replication datastore. This
1070 utility allows you to copy the bulk of your data in the background, while the

1148 BlobstoreService.createUploadUrl().
1149 - Zigzag merge join queries will now continue scanning up to the 30 second
1150 Datastore query deadline. For zigzag queries that used to generate
1151 DatastoreNeedIndexException, many will now succeed. A small percentage will
1152 now instead timeout.
1153 - The SDK datastore viewer in the dev console now displays the number of "Write
1154 Ops" for each entity. "Write Ops" are the total number of entity and index
1155 writes that were required to create the entity.

1433 http://code.google.com/p/googleappengine/issues/detail?id=4216
1437 There were no updates to the Java SDK for the 1.4.1 App Engine release.
1441 - The Always On feature allows applications to pay and keep 3 instances of their
1442 application always running, which can significantly reduce application
1444 - Developers can now enable Warmup Requests. By specifying a handler in an
1445 app's appengine-web.xml, App Engine will attempt to send a Warmup Request to
1446 initialize new instances before a user interacts with it. This can reduce the
1447 latency an end-user sees for initializing your application.
1448 - The Channel API is now available for all users.
1449 - Task Queue has been officially released, and is no longer an experimental
1450 feature. The API import paths that use 'labs' have been deprecated. Task queue
1451 storage will count towards an application's overall storage quota, and will
1452 thus be charged for.
1453 - The deadline for Task Queue and Cron requests has been raised to 10 minutes.
1454 Datastore and API deadlines within those requests remain unchanged.
1455 - For the Task Queue, developers can specify task retry-parameters in their
1457 - Apps that have enabled billing are allowed up to 100 queues with the Task
1459 - Metadata Queries on the datastore for datastore kinds, namespaces, and entity
1460 properties are available.
1461 - URL Fetch allowed response size has been increased, up to 32 MB. Request size
1462 is still limited to 1 MB.
1463 - The request and response sizes for the Images API have been increased to
1465 - The total size of Memcache batch operations is increased to 32 MB. The 1 MB
1466 limit on individual Memcache objects still applies.
1467 - The attachment size for outgoing emails has been increased from 1 MB to 10 MB.
1468 The size limit for incoming emails is still 10 MB.
1469 - Size and quantity limits on datastore batch get/put/delete operations have
1470 been removed. Individual entities are still limited to 1 MB, but your app may
1471 batch as many entities together for get/put/delete calls as the overall
1472 datastore deadline will allow for.
1473 - When iterating over query results, the datastore will now asynchronously
1474 prefetch results, reducing latency in many cases by 10-15%.
1475 - The Admin Console Blacklist page lists the top blacklist rejected visitors.
1476 - The automatic image thumbnailing service supports arbitrary crop sizes up to
1478 - Overall average instance latency in the Admin Console is now a weighted
1479 average over QPS per instance.
1480 - Added a low-level AysncDatastoreService for making calls to the datastore
1482 - Added a getBodyAsBytes() method to QueueStateInfo.TaskStateInfo, this returns
1483 the body of the task state as a pure byte-string.
1484 - The whitelist has been updated to include all classes from javax.xml.soap.
1485 - Fixed an issue sending email to multiple recipients.

1498 sessions. For more information see:
1499 http://www.google.com/support/accounts/bin/answer.py?answer=181599
1500 - In queue.xml, the maximum allowed bucket size is now 100.
1501 - Removed limits on zigzag merge-join queries. Therefore the error "The built-in
1502 indices are not efficient enough for this query and your data. Please add a
1503 composite index for this query." will no longer be thrown in most cases,
1504 enabling more types of queries without indexes.
1505 - The whitelist has been updated to include java.net.InetAddress and some
1506 interfaces and abstract classes in javax.xml.soap, including
1507 javax.xml.soap.SOAPMessage.
