274 ListIndexesException, ListIndexesRequest, ListIndexesResponse, ListRequest,
275 ListResponse, and RemoveException were removed from the Search API in the
276 SDK. If your app references any of these classes, you must deploy a new
277 version without these references before the next release of App Engine.
278 If you do not do this, your app may stop working in production.
279 - The Conversion API, which was decommissioned last release, has been removed

1047 - Fixed a bug that caused appengine-jsr107cache-1.5.0.jar to be empty.
1051 - Support for Backends which allow developers to create infrastructure
1052 components that complement the existing dynamic apps that App Engine already
1053 provides. Instances of a backend can maintain state, be addressed
1054 individually, and are not subject to per-request time limits. They can also be
1055 configured to consume more memory and CPU than ordinary dynamic instances.
1056 - Task Queues support pull mode, allowing for more control over task queue work
1057 rates. To use pull queues, include the 'mode' element in your queue.xml.
1058 - Pull queues are supported by a REST API, allowing access from outside App
1059 Engine. To use the REST API, you must also include a valid ACL section
1060 specifying which users can lease tasks from the pull queue.
1061 - Task Queue payload limits have been increased. Queues support 100KB per task.
1062 Within App Engine, the new limit is 32 MB per batch of tasks. With the REST

1068 Datastore as the default configuration option. Developers that still wish to
1069 use the Master/Slave configuration must explicitly choose this option at
1070 application creation time.
1071 - The Task Queue maximum configurable processing rate has been increased to
1073 - Modified Dashboard latency graphs to indicate they only include dynamic

1212 - The Always On feature allows applications to pay and keep 3 instances of their
1213 application always running, which can significantly reduce application
1215 - Developers can now enable Warmup Requests. By specifying a handler in an
1216 app's appengine-web.xml, App Engine will attempt to send a Warmup Request to
1217 initialize new instances before a user interacts with it. This can reduce the
1218 latency an end-user sees for initializing your application.
1219 - The Channel API is now available for all users.
1220 - Task Queue has been officially released, and is no longer an experimental
1221 feature. The API import paths that use 'labs' have been deprecated. Task queue
1222 storage will count towards an application's overall storage quota, and will
1223 thus be charged for.

1239 The size limit for incoming emails is still 10 MB.
1240 - Size and quantity limits on datastore batch get/put/delete operations have
1241 been removed. Individual entities are still limited to 1 MB, but your app may
1242 batch as many entities together for get/put/delete calls as the overall
1243 datastore deadline will allow for.
1244 - When iterating over query results, the datastore will now asynchronously
1245 prefetch results, reducing latency in many cases by 10-15%.
1246 - The Admin Console Blacklist page lists the top blacklist rejected visitors.
1247 - The automatic image thumbnailing service supports arbitrary crop sizes up to

1271 - In queue.xml, the maximum allowed bucket size is now 100.
1272 - Removed limits on zigzag merge-join queries. Therefore the error "The built-in
1273 indices are not efficient enough for this query and your data. Please add a
1274 composite index for this query." will no longer be thrown in most cases,
1275 enabling more types of queries without indexes.
1276 - The whitelist has been updated to include java.net.InetAddress and some
1277 interfaces and abstract classes in javax.xml.soap, including
1278 javax.xml.soap.SOAPMessage.
1279 - Fixed an issue reserving App Ids by owners of emails containing periods,
1280 multiple cases, and googlemail.com address.
