41 HTTP method. This new behavior is in line with modern conventions (see
42 http://tools.ietf.org/html/rfc7231#section-6.4). You can
43 use the final_url field of the Response object (or a similar object in other
44 APIs, see https://cloud.google.com/appengine/docs/java/urlfetch/) to
45 determine if your fetches are being redirected. If this change affects your
46 application, please contact our support team - even if you do not have a

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

176 https://developers.google.com/appengine/docs/java/modules/#Java_Configuration
180 - Java 6 applications cannot be deployed to Google App Engine from any version
181 of the SDK. Existing Java 6 applications will continue to run. If you are
182 still relying on a Java 6 application in Google App Engine, we strongly
183 encourage you to start testing and deploying your app using Java 7. Java 7
184 has been certified by Oracle to be fully backwards compatible with Java 6,
185 as well as providing a number of benefits to developers. Java 7 applications
186 will be fully supported in future releases of the App Engine SDK.
187 If you absolutely need to continue to deploy Java 6 applications for
188 compatibility reasons, you can request that your application be whitelisted
189 for Java 6 deployment from http://goo.gl/ycffXq. As we review each whitelist
190 application by hand, please allow 10 working days for review, and note that
191 only billed applications that show a proven incompatibility will be
192 considered for exemption.

1011 - Fixed an issue in the Java Pipeline API
1012 (http://code.google.com/p/appengine-pipeline/) that would lead to "No object
1013 found in pool with id=barrier(...)" errors when used in HRD applications.
1018 - In the Admin Console, you can use the new Traffic Splitting feature to send a
1019 certain percentage of traffic to a non-default application version. The
1020 traffic is split by either cookie or IP address.
1021 - Emails that are sent from Google Apps domains email addresses where the domain
1022 has been set up to use DKIM will be signed: when an email was from a request
1023 that originated on that app's domain or any time the email was sent from
1024 an app adminstrator, including when that email is sent from a cron job or task
1026 - In the Admin Console, you can now choose how much and how long you'd like to
1027 store logs. All apps get 1G for free and eventually will be able to pay for

1029 for the additional capacity until the next release at the earliest.
1030 - The instances screen in the Admin Console now has a button to shut down
1031 a specific instance.
1032 - Each application log has a link to the instance that served the request. If
1033 the instance is no longer serving requests, a message will be displayed.
1034 - The TaskQueue API now supports the ability to tag a Pull Queue task. You may
1035 then lease tasks by tag. This feature is experimental.

1056 application quota, including Instance Hours, Datastore Ops and Datastore
1058 - Developers can now specify how long a channel token will last until it
1059 expires, with the default remaining two hours. Channel API quota is now
1060 measured both in calls to create a channel and the number of hours of channel
1061 time requested. The maximum hours of quota is the maximum number of channel
1062 creation calls * 2, so free apps get 200 hours of requested channel token
1064 - Task Queue API requests now include a X-Appengine-TaskETA header, that can be
1065 used to measure task delivery latency.
1066 - We have removed the deprecated labs version of the TaskQueue API.

1078 http://code.google.com/p/googleappengine/issues/detail?id=5545
1082 - You can now configure Frontend Instance Classes from your Admin Console's
1083 application settings page. Three classes are available, with increasing
1084 memory, CPU limits, and associated cost. By default, all applications use the
1085 basic frontend instance setting of 128MB memory and 600MHz CPU.
1086 - We've added new functionality to the Log API that will allow you to read your
1087 application's logs programmatically.

1119 this was included in Datastore storage.
1120 - We have released an experimental utility, available in the Admin Console, to
1121 assist in migrating your application to the High Replication datastore. This
1122 utility allows you to copy the bulk of your data in the background, while the
1123 source application is still serving. You then need a brief read-only period to
1124 migrate your application data while you copy the data that has changed from
1125 the time the original copy started.
1126 - Blobstore, which was previously limited to apps with billing enabled, is now
1127 available for all apps.

1176 Replication Datastore, which allow you to perform transactions across multiple
1178 http://code.google.com/appengine/docs/java/datastore/transactions.html
1179 - We have added a graph to the admin console that displays the number of
1180 instances for which you will be billed.
1181 - In the XMPP API, getPresence() is deprecated in favor of using the inbound
1182 presence handlers documented in

1200 BlobstoreService.createUploadUrl().
1201 - Zigzag merge join queries will now continue scanning up to the 30 second
1202 Datastore query deadline. For zigzag queries that used to generate
1203 DatastoreNeedIndexException, many will now succeed. A small percentage will
1204 now instead timeout.
1205 - The SDK datastore viewer in the dev console now displays the number of "Write
1206 Ops" for each entity. "Write Ops" are the total number of entity and index
1207 writes that were required to create the entity.
1208 - The Prospective Search API is available in Java for all applications. This API
1209 is still experimental, so applications will be limited to a maximum of 1000

1335 individually, and are not subject to per-request time limits. They can also be
1336 configured to consume more memory and CPU than ordinary dynamic instances.
1337 - Task Queues support pull mode, allowing for more control over task queue work
1338 rates. To use pull queues, include the 'mode' element in your queue.xml.

1349 Datastore as the default configuration option. Developers that still wish to
1350 use the Master/Slave configuration must explicitly choose this option at
1351 application creation time.
1352 - The Task Queue maximum configurable processing rate has been increased to
1354 - Modified Dashboard latency graphs to indicate they only include dynamic
1356 - We have added two restrictions to the Mail API to improve the reliability
1357 of the service for all applications.

1493 - The Always On feature allows applications to pay and keep 3 instances of their
1494 application always running, which can significantly reduce application
1496 - Developers can now enable Warmup Requests. By specifying a handler in an
1497 app's appengine-web.xml, App Engine will attempt to send a Warmup Request to
1498 initialize new instances before a user interacts with it. This can reduce the
1499 latency an end-user sees for initializing your application.
1500 - The Channel API is now available for all users.
1501 - Task Queue has been officially released, and is no longer an experimental
1502 feature. The API import paths that use 'labs' have been deprecated. Task queue
1503 storage will count towards an application's overall storage quota, and will

1520 The size limit for incoming emails is still 10 MB.
1521 - Size and quantity limits on datastore batch get/put/delete operations have
1522 been removed. Individual entities are still limited to 1 MB, but your app may
1523 batch as many entities together for get/put/delete calls as the overall
1524 datastore deadline will allow for.
1525 - When iterating over query results, the datastore will now asynchronously
1526 prefetch results, reducing latency in many cases by 10-15%.

1552 - In queue.xml, the maximum allowed bucket size is now 100.
1553 - Removed limits on zigzag merge-join queries. Therefore the error "The built-in
1554 indices are not efficient enough for this query and your data. Please add a
1555 composite index for this query." will no longer be thrown in most cases,
1556 enabling more types of queries without indexes.
1557 - The whitelist has been updated to include java.net.InetAddress and some
1558 interfaces and abstract classes in javax.xml.soap, including
1559 javax.xml.soap.SOAPMessage.
