4 App Engine Java SDK - Release Notes
8 - Improvements to the App Engine billing system will be rolled out gradually to
10 - The application summary no longer displays the default version of a running
11 application, instead it lists the application as 'RUNNING'. In an upcoming
12 release applications will have multiple logical sub components, each of which
13 will have a default version. This UI update is meant to align with this
15 - Projection queries are now a fully supported GA feature.
16 - The XMPP API now has multi-JID getPresence(). This provides the ability to get
17 the availability of multiple users.
18 - The Java dev_appserver now allocates automatic ids using the 'scattered' id
19 allocation policy by default. For more information, please see "Specifying the
20 Automatic ID Allocation Policy":
21 https://developers.google.com/appengine/docs/java/tools/devserver#Using_the_
23 - Admin console dashboard charts and current load/errors reports will be moving
24 to a new, more reliable backend. The change will be gradually rolling to users
25 of admin console over the next few weeks.
26 - New Search API quotas are now displayed in the Admin Console. These quotas are
27 not currently enforced, but will be part of the pricing model for the Search
28 API in a future release.
29 - The experimental Search API's ability to explicitly sort search results by
30 SortExpression.RANK_FIELD_NAME (i.e. _order_id) field in ascending order has
32 - Globally consistent indexes in the experimental Search API are now deprecated
33 and will be removed in the next release.
34 - Task Queue tasks may now be added and deleted asynchronously. This allows
35 applications to perform common task queue operations without blocking. This is
36 an experimental feature.
37 - Fixed an issue which caused an incorrect server error message when setting the
38 default version on the admin console, though the version was set correctly.
39 - Fixed an issue that caused java.security.AccessControlException when creating
41 - Fixed an issue that caused NullPointerException in ListIndexesResponse

45 https://code.google.com/p/googleappengine/issues/detail?id=8851
49 - New instance classes F4_1G and B4_1G are now available. These instances have
50 compute capacity equal to F4/B4 but with a maximum of 1G RAM instead
52 - The DataNucleus plugin has been upgraded to 2.1.2.
53 - The deprecated classes AddException, AddResponse, ListException,
54 ListIndexesException, ListIndexesRequest, ListIndexesResponse, ListRequest,
55 ListResponse, and RemoveException were removed from the Search API in the
56 SDK. If your app references any of these classes, you must deploy a new
57 version without these references before the next release of App Engine.
58 If you do not do this, your app may stop working in production.
59 - The Conversion API, which was decommissioned last release, has been removed
60 from the SDK. In a future release, the API will be removed from the
61 runtime and applications that attempt to use it may stop working.

519 traffic is split by either cookie or IP address.
520 - Emails that are sent from Google Apps domains email addresses where the domain
521 has been set up to use DKIM will be signed: when an email was from a request
522 that originated on that app's domain or any time the email was sent from
523 an app adminstrator, including when that email is sent from a cron job or task
525 - In the Admin Console, you can now choose how much and how long you'd like to
526 store logs. All apps get 1G for free and eventually will be able to pay for

555 application quota, including Instance Hours, Datastore Ops and Datastore
557 - Developers can now specify how long a channel token will last until it
558 expires, with the default remaining two hours. Channel API quota is now
559 measured both in calls to create a channel and the number of hours of channel
560 time requested. The maximum hours of quota is the maximum number of channel
561 creation calls * 2, so free apps get 200 hours of requested channel token
563 - Task Queue API requests now include a X-Appengine-TaskETA header, that can be
564 used to measure task delivery latency.
565 - We have removed the deprecated labs version of the TaskQueue API.

705 Ops" for each entity. "Write Ops" are the total number of entity and index
706 writes that were required to create the entity.
707 - The Prospective Search API is available in Java for all applications. This API
708 is still experimental, so applications will be limited to a maximum of 1000
710 - We made a classloading improvement that we expect to help loading request
711 latencies for projects with large numbers of jars.
712 - Added support for the set_default_version flag to Appcfg.

995 - Developers can now enable Warmup Requests. By specifying a handler in an
996 app's appengine-web.xml, App Engine will attempt to send a Warmup Request to
997 initialize new instances before a user interacts with it. This can reduce the
998 latency an end-user sees for initializing your application.
999 - The Channel API is now available for all users.
1000 - Task Queue has been officially released, and is no longer an experimental
1001 feature. The API import paths that use 'labs' have been deprecated. Task queue

1021 been removed. Individual entities are still limited to 1 MB, but your app may
1022 batch as many entities together for get/put/delete calls as the overall
1023 datastore deadline will allow for.
1024 - When iterating over query results, the datastore will now asynchronously
1025 prefetch results, reducing latency in many cases by 10-15%.

1051 - In queue.xml, the maximum allowed bucket size is now 100.
1052 - Removed limits on zigzag merge-join queries. Therefore the error "The built-in
1053 indices are not efficient enough for this query and your data. Please add a
1054 composite index for this query." will no longer be thrown in most cases,
1055 enabling more types of queries without indexes.
