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

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

1032 - In the Admin Console, you can use the new Traffic Splitting feature to send a
1033 certain percentage of traffic to a non-default application version. The
1034 traffic is split by either cookie or IP address.
1035 - Emails that are sent from Google Apps domains email addresses where the domain
1036 has been set up to use DKIM will be signed: when an email was from a request

1070 application quota, including Instance Hours, Datastore Ops and Datastore
1072 - Developers can now specify how long a channel token will last until it
1073 expires, with the default remaining two hours. Channel API quota is now
1074 measured both in calls to create a channel and the number of hours of channel
1075 time requested. The maximum hours of quota is the maximum number of channel
1076 creation calls * 2, so free apps get 200 hours of requested channel token
1078 - Task Queue API requests now include a X-Appengine-TaskETA header, that can be
1079 used to measure task delivery latency.
1080 - We have removed the deprecated labs version of the TaskQueue API.

1133 this was included in Datastore storage.
1134 - We have released an experimental utility, available in the Admin Console, to
1135 assist in migrating your application to the High Replication datastore. This
1136 utility allows you to copy the bulk of your data in the background, while the

1190 Replication Datastore, which allow you to perform transactions across multiple
1192 http://code.google.com/appengine/docs/java/datastore/transactions.html
1193 - We have added a graph to the admin console that displays the number of
1194 instances for which you will be billed.
1195 - In the XMPP API, getPresence() is deprecated in favor of using the inbound
1196 presence handlers documented in

1214 BlobstoreService.createUploadUrl().
1215 - Zigzag merge join queries will now continue scanning up to the 30 second
1216 Datastore query deadline. For zigzag queries that used to generate
1217 DatastoreNeedIndexException, many will now succeed. A small percentage will
1218 now instead timeout.
1219 - The SDK datastore viewer in the dev console now displays the number of "Write
1220 Ops" for each entity. "Write Ops" are the total number of entity and index
1221 writes that were required to create the entity.

1507 - The Always On feature allows applications to pay and keep 3 instances of their
1508 application always running, which can significantly reduce application
1510 - Developers can now enable Warmup Requests. By specifying a handler in an
1511 app's appengine-web.xml, App Engine will attempt to send a Warmup Request to
1512 initialize new instances before a user interacts with it. This can reduce the
1513 latency an end-user sees for initializing your application.
1514 - The Channel API is now available for all users.
1515 - Task Queue has been officially released, and is no longer an experimental
1516 feature. The API import paths that use 'labs' have been deprecated. Task queue
1517 storage will count towards an application's overall storage quota, and will
1518 thus be charged for.

1528 is still limited to 1 MB.
1529 - The request and response sizes for the Images API have been increased to
1531 - The total size of Memcache batch operations is increased to 32 MB. The 1 MB
1532 limit on individual Memcache objects still applies.
1533 - The attachment size for outgoing emails has been increased from 1 MB to 10 MB.
1534 The size limit for incoming emails is still 10 MB.
1535 - Size and quantity limits on datastore batch get/put/delete operations have
1536 been removed. Individual entities are still limited to 1 MB, but your app may
1537 batch as many entities together for get/put/delete calls as the overall
1538 datastore deadline will allow for.
1539 - When iterating over query results, the datastore will now asynchronously
1540 prefetch results, reducing latency in many cases by 10-15%.
1541 - The Admin Console Blacklist page lists the top blacklist rejected visitors.
1542 - The automatic image thumbnailing service supports arbitrary crop sizes up to
1544 - Overall average instance latency in the Admin Console is now a weighted
1545 average over QPS per instance.
1546 - Added a low-level AysncDatastoreService for making calls to the datastore
1548 - Added a getBodyAsBytes() method to QueueStateInfo.TaskStateInfo, this returns
1549 the body of the task state as a pure byte-string.
1550 - The whitelist has been updated to include all classes from javax.xml.soap.
1551 - Fixed an issue sending email to multiple recipients.

1564 sessions. For more information see:
1565 http://www.google.com/support/accounts/bin/answer.py?answer=181599
1566 - In queue.xml, the maximum allowed bucket size is now 100.
1567 - Removed limits on zigzag merge-join queries. Therefore the error "The built-in
1568 indices are not efficient enough for this query and your data. Please add a
1569 composite index for this query." will no longer be thrown in most cases,
1570 enabling more types of queries without indexes.
1571 - The whitelist has been updated to include java.net.InetAddress and some
1572 interfaces and abstract classes in javax.xml.soap, including
1573 javax.xml.soap.SOAPMessage.
