99 - We are pleased to announce the availability of Dedicated Memcache service
100 to our customers in the EU.
104 - The Performance Settings section of the Application settings page in the
105 Admin Console, Backends API and all backends related management tools are now
106 deprecated and will be removed in a future release. Users of Backends are
107 recommended to migrate to the App Engine Modules API, which provides a more
108 flexible implementation of the same functionality. These settings are now all
109 configurable via Modules configuration files.

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

432 runtime, please use the --use_java6 flag when deploying your app. We encourage
433 you to move to Java7 as soon as possible.
434 - Billing enabled apps will no longer be subject to a $2.10 minimum weekly
435 spend. Instead, apps will only be charged for their actual usage.
436 - Fixed an issue where Datastore auto ids assigned by the scattered id
437 policy were too large to be represented as floating point numbers in the SDK.
438 - Fixed an issue with sort by doc_id not translating correctly causing

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

489 - The deprecated classes AddException, AddResponse, ListException,
490 ListIndexesException, ListIndexesRequest, ListIndexesResponse, ListRequest,
491 ListResponse, and RemoveException were removed from the Search API in the
492 SDK. If your app references any of these classes, you must deploy a new
493 version without these references before the next release of App Engine.
494 If you do not do this, your app may stop working in production.
495 - The Conversion API, which was decommissioned last release, has been removed
496 from the SDK. In a future release, the API will be removed from the
497 runtime and applications that attempt to use it may stop working.

993 - Developers can now specify how long a channel token will last until it
994 expires, with the default remaining two hours. Channel API quota is now
995 measured both in calls to create a channel and the number of hours of channel
996 time requested. The maximum hours of quota is the maximum number of channel
997 creation calls * 2, so free apps get 200 hours of requested channel token
999 - Task Queue API requests now include a X-Appengine-TaskETA header, that can be
1000 used to measure task delivery latency.
1001 - We have removed the deprecated labs version of the TaskQueue API.

1054 this was included in Datastore storage.
1055 - We have released an experimental utility, available in the Admin Console, to
1056 assist in migrating your application to the High Replication datastore. This
1057 utility allows you to copy the bulk of your data in the background, while the

1135 BlobstoreService.createUploadUrl().
1136 - Zigzag merge join queries will now continue scanning up to the 30 second
1137 Datastore query deadline. For zigzag queries that used to generate
1138 DatastoreNeedIndexException, many will now succeed. A small percentage will
1139 now instead timeout.
1140 - The SDK datastore viewer in the dev console now displays the number of "Write
1141 Ops" for each entity. "Write Ops" are the total number of entity and index
1142 writes that were required to create the entity.
1143 - The Prospective Search API is available in Java for all applications. This API
1144 is still experimental, so applications will be limited to a maximum of 1000

1431 - Developers can now enable Warmup Requests. By specifying a handler in an
1432 app's appengine-web.xml, App Engine will attempt to send a Warmup Request to
1433 initialize new instances before a user interacts with it. This can reduce the
1434 latency an end-user sees for initializing your application.
1435 - The Channel API is now available for all users.
1436 - Task Queue has been officially released, and is no longer an experimental
1437 feature. The API import paths that use 'labs' have been deprecated. Task queue
1438 storage will count towards an application's overall storage quota, and will

1455 The size limit for incoming emails is still 10 MB.
1456 - Size and quantity limits on datastore batch get/put/delete operations have
1457 been removed. Individual entities are still limited to 1 MB, but your app may
1458 batch as many entities together for get/put/delete calls as the overall
1459 datastore deadline will allow for.
1460 - When iterating over query results, the datastore will now asynchronously
1461 prefetch results, reducing latency in many cases by 10-15%.

1487 - In queue.xml, the maximum allowed bucket size is now 100.
1488 - Removed limits on zigzag merge-join queries. Therefore the error "The built-in
1489 indices are not efficient enough for this query and your data. Please add a
1490 composite index for this query." will no longer be thrown in most cases,
1491 enabling more types of queries without indexes.

1493 interfaces and abstract classes in javax.xml.soap, including
1494 javax.xml.soap.SOAPMessage.
