50 - The URL Fetch service will always issue a GET request when it receives
51 and responds to a 302 response; previously it would preserve the original
52 HTTP method. This new behavior is in line with modern conventions (see
53 http://tools.ietf.org/html/rfc7231#section-6.4). You can
54 use the final_url field of the Response object (or a similar object in other
55 APIs, see https://cloud.google.com/appengine/docs/java/urlfetch/) to
56 determine if your fetches are being redirected. If this change affects your
57 application, please contact our support team - even if you do not have a

180 - The Performance Settings section of the Application settings page in the
181 Admin Console, Backends API and all backends related management tools are now
182 deprecated and will be removed in a future release. Users of Backends are
183 recommended to migrate to the App Engine Modules API, which provides a more
184 flexible implementation of the same functionality. These settings are now all
185 configurable via Modules configuration files.
186 See the Modules documentation for more information:
187 https://developers.google.com/appengine/docs/java/modules/#Java_Configuration
191 - Java 6 applications cannot be deployed to Google App Engine from any version
192 of the SDK. Existing Java 6 applications will continue to run. If you are
193 still relying on a Java 6 application in Google App Engine, we strongly
194 encourage you to start testing and deploying your app using Java 7. Java 7
195 has been certified by Oracle to be fully backwards compatible with Java 6,
196 as well as providing a number of benefits to developers. Java 7 applications
197 will be fully supported in future releases of the App Engine SDK.
198 If you absolutely need to continue to deploy Java 6 applications for
199 compatibility reasons, you can request that your application be whitelisted
200 for Java 6 deployment from http://goo.gl/ycffXq. As we review each whitelist
201 application by hand, please allow 10 working days for review, and note that
202 only billed applications that show a proven incompatibility will be
203 considered for exemption.
204 - Newly created App Engine applications now have a Google Cloud Storage bucket

1022 - Fixed an issue in the Java Pipeline API
1023 (http://code.google.com/p/appengine-pipeline/) that would lead to "No object
1024 found in pool with id=barrier(...)" errors when used in HRD applications.
1029 - In the Admin Console, you can use the new Traffic Splitting feature to send a
1030 certain percentage of traffic to a non-default application version. The
1031 traffic is split by either cookie or IP address.
1032 - Emails that are sent from Google Apps domains email addresses where the domain
1033 has been set up to use DKIM will be signed: when an email was from a request

1067 application quota, including Instance Hours, Datastore Ops and Datastore
1069 - Developers can now specify how long a channel token will last until it
1070 expires, with the default remaining two hours. Channel API quota is now
1071 measured both in calls to create a channel and the number of hours of channel
1072 time requested. The maximum hours of quota is the maximum number of channel
1073 creation calls * 2, so free apps get 200 hours of requested channel token
1075 - Task Queue API requests now include a X-Appengine-TaskETA header, that can be
1076 used to measure task delivery latency.
1077 - We have removed the deprecated labs version of the TaskQueue API.

1130 this was included in Datastore storage.
1131 - We have released an experimental utility, available in the Admin Console, to
1132 assist in migrating your application to the High Replication datastore. This
1133 utility allows you to copy the bulk of your data in the background, while the
1134 source application is still serving. You then need a brief read-only period to
1135 migrate your application data while you copy the data that has changed from
1136 the time the original copy started.
1137 - Blobstore, which was previously limited to apps with billing enabled, is now
1138 available for all apps.

1187 Replication Datastore, which allow you to perform transactions across multiple
1189 http://code.google.com/appengine/docs/java/datastore/transactions.html
1190 - We have added a graph to the admin console that displays the number of
1191 instances for which you will be billed.
1192 - In the XMPP API, getPresence() is deprecated in favor of using the inbound
1193 presence handlers documented in

1211 BlobstoreService.createUploadUrl().
1212 - Zigzag merge join queries will now continue scanning up to the 30 second
1213 Datastore query deadline. For zigzag queries that used to generate
1214 DatastoreNeedIndexException, many will now succeed. A small percentage will
1215 now instead timeout.
1216 - The SDK datastore viewer in the dev console now displays the number of "Write
1217 Ops" for each entity. "Write Ops" are the total number of entity and index
1218 writes that were required to create the entity.
1219 - The Prospective Search API is available in Java for all applications. This API
1220 is still experimental, so applications will be limited to a maximum of 1000

1346 individually, and are not subject to per-request time limits. They can also be
1347 configured to consume more memory and CPU than ordinary dynamic instances.
1348 - Task Queues support pull mode, allowing for more control over task queue work
1349 rates. To use pull queues, include the 'mode' element in your queue.xml.

1360 Datastore as the default configuration option. Developers that still wish to
1361 use the Master/Slave configuration must explicitly choose this option at
1362 application creation time.
1363 - The Task Queue maximum configurable processing rate has been increased to
1365 - Modified Dashboard latency graphs to indicate they only include dynamic
1367 - We have added two restrictions to the Mail API to improve the reliability
1368 of the service for all applications.

1504 - The Always On feature allows applications to pay and keep 3 instances of their
1505 application always running, which can significantly reduce application
1507 - Developers can now enable Warmup Requests. By specifying a handler in an
1508 app's appengine-web.xml, App Engine will attempt to send a Warmup Request to
1509 initialize new instances before a user interacts with it. This can reduce the
1510 latency an end-user sees for initializing your application.
1511 - The Channel API is now available for all users.
1512 - Task Queue has been officially released, and is no longer an experimental
1513 feature. The API import paths that use 'labs' have been deprecated. Task queue
1514 storage will count towards an application's overall storage quota, and will
1515 thus be charged for.

1531 The size limit for incoming emails is still 10 MB.
1532 - Size and quantity limits on datastore batch get/put/delete operations have
1533 been removed. Individual entities are still limited to 1 MB, but your app may
1534 batch as many entities together for get/put/delete calls as the overall
1535 datastore deadline will allow for.
1536 - When iterating over query results, the datastore will now asynchronously
1537 prefetch results, reducing latency in many cases by 10-15%.
1538 - The Admin Console Blacklist page lists the top blacklist rejected visitors.
1539 - The automatic image thumbnailing service supports arbitrary crop sizes up to
1541 - Overall average instance latency in the Admin Console is now a weighted

1543 - Added a low-level AysncDatastoreService for making calls to the datastore
1545 - Added a getBodyAsBytes() method to QueueStateInfo.TaskStateInfo, this returns
1546 the body of the task state as a pure byte-string.
1547 - The whitelist has been updated to include all classes from javax.xml.soap.

1563 - In queue.xml, the maximum allowed bucket size is now 100.
1564 - Removed limits on zigzag merge-join queries. Therefore the error "The built-in
1565 indices are not efficient enough for this query and your data. Please add a
1566 composite index for this query." will no longer be thrown in most cases,
1567 enabling more types of queries without indexes.
1568 - The whitelist has been updated to include java.net.InetAddress and some
1569 interfaces and abstract classes in javax.xml.soap, including
1570 javax.xml.soap.SOAPMessage.
