8 - Fixed an issue with Datastore stats not displaying entity counts.
9 https://code.google.com/p/googleappengine/issues/detail?id=9328
13 - The URL Fetch service will always issue a GET request when it receives
14 and responds to a 302 response; previously it would preserve the original
15 HTTP method. This new behavior is in line with modern conventions (see
16 http://tools.ietf.org/html/rfc7231#section-6.4). You can
17 use the final_url field of the Response object (or a similar object in other
18 APIs, see https://cloud.google.com/appengine/docs/java/urlfetch/) to
19 determine if your fetches are being redirected. If this change affects your
20 application, please contact our support team - even if you do not have a

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

150 https://developers.google.com/appengine/docs/java/modules/#Java_Configuration
154 - Java 6 applications cannot be deployed to Google App Engine from any version
155 of the SDK. Existing Java 6 applications will continue to run. If you are
156 still relying on a Java 6 application in Google App Engine, we strongly
157 encourage you to start testing and deploying your app using Java 7. Java 7
158 has been certified by Oracle to be fully backwards compatible with Java 6,
159 as well as providing a number of benefits to developers. Java 7 applications
160 will be fully supported in future releases of the App Engine SDK.
161 If you absolutely need to continue to deploy Java 6 applications for
162 compatibility reasons, you can request that your application be whitelisted
163 for Java 6 deployment from http://goo.gl/ycffXq. As we review each whitelist
164 application by hand, please allow 10 working days for review, and note that
165 only billed applications that show a proven incompatibility will be
166 considered for exemption.

411 billing enabled can exceed the free quota levels and will be charged for
412 usage above these levels.
413 - Estimated number of search results will only be accurate if it is less than
414 or equal to the number of results requested. By default this can be

444 to get email quotas increased.
445 - Admin console dashboard charts and reports for all users have been fully
446 migrated to the new, more reliable backend announced in 1.7.6.
447 - The maximum size of POST requests made through URLfetch has been increased

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

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

527 - The DataNucleus plugin has been upgraded to 2.1.2.
528 - The deprecated classes AddException, AddResponse, ListException,
529 ListIndexesException, ListIndexesRequest, ListIndexesResponse, ListRequest,
530 ListResponse, and RemoveException were removed from the Search API in the
531 SDK. If your app references any of these classes, you must deploy a new
532 version without these references before the next release of App Engine.
533 If you do not do this, your app may stop working in production.
534 - The Conversion API, which was decommissioned last release, has been removed
535 from the SDK. In a future release, the API will be removed from the
536 runtime and applications that attempt to use it may stop working.
537 Applications in production that import the library should be fixed as soon as

998 an app adminstrator, including when that email is sent from a cron job or task
1000 - In the Admin Console, you can now choose how much and how long you'd like to
1001 store logs. All apps get 1G for free and eventually will be able to pay for

1030 application quota, including Instance Hours, Datastore Ops and Datastore
1032 - Developers can now specify how long a channel token will last until it
1033 expires, with the default remaining two hours. Channel API quota is now
1034 measured both in calls to create a channel and the number of hours of channel
1035 time requested. The maximum hours of quota is the maximum number of channel
1036 creation calls * 2, so free apps get 200 hours of requested channel token
1038 - Task Queue API requests now include a X-Appengine-TaskETA header, that can be
1039 used to measure task delivery latency.
1040 - We have removed the deprecated labs version of the TaskQueue API.

1093 this was included in Datastore storage.
1094 - We have released an experimental utility, available in the Admin Console, to
1095 assist in migrating your application to the High Replication datastore. This
1096 utility allows you to copy the bulk of your data in the background, while the

1174 BlobstoreService.createUploadUrl().
1175 - Zigzag merge join queries will now continue scanning up to the 30 second
1176 Datastore query deadline. For zigzag queries that used to generate
1177 DatastoreNeedIndexException, many will now succeed. A small percentage will
1178 now instead timeout.
1179 - The SDK datastore viewer in the dev console now displays the number of "Write
1180 Ops" for each entity. "Write Ops" are the total number of entity and index
1181 writes that were required to create the entity.

1467 - The Always On feature allows applications to pay and keep 3 instances of their
1468 application always running, which can significantly reduce application
1470 - Developers can now enable Warmup Requests. By specifying a handler in an
1471 app's appengine-web.xml, App Engine will attempt to send a Warmup Request to
1472 initialize new instances before a user interacts with it. This can reduce the
1473 latency an end-user sees for initializing your application.
1474 - The Channel API is now available for all users.
1475 - Task Queue has been officially released, and is no longer an experimental
1476 feature. The API import paths that use 'labs' have been deprecated. Task queue
1477 storage will count towards an application's overall storage quota, and will
1478 thus be charged for.

1494 The size limit for incoming emails is still 10 MB.
1495 - Size and quantity limits on datastore batch get/put/delete operations have
1496 been removed. Individual entities are still limited to 1 MB, but your app may
1497 batch as many entities together for get/put/delete calls as the overall
1498 datastore deadline will allow for.
1499 - When iterating over query results, the datastore will now asynchronously
1500 prefetch results, reducing latency in many cases by 10-15%.

1526 - In queue.xml, the maximum allowed bucket size is now 100.
1527 - Removed limits on zigzag merge-join queries. Therefore the error "The built-in
1528 indices are not efficient enough for this query and your data. Please add a
1529 composite index for this query." will no longer be thrown in most cases,
1530 enabling more types of queries without indexes.

1532 interfaces and abstract classes in javax.xml.soap, including
1533 javax.xml.soap.SOAPMessage.
