84 now available as a Preview feature. More information can be found at
85 https://code.google.com/p/appengine-gcs-client/
86 - Bandwidth between App Engine and Google Cloud Storage is currently free of
87 charge (this may change in the future for certain levels of service).
88 - The Search API has graduated from Experimental to Preview. Apps that have
89 billing enabled can exceed the free quota levels and will be charged for
90 usage above these levels.
91 - Estimated number of search results will only be accurate if it is less than
92 or equal to the number of results requested. By default this can be
93 overridden by setting number_found_accuracy QueryOption in the Search API.
94 - Dates, atoms, and number fields can now be found by searching without a field
95 restriction in the Search API.

122 to get email quotas increased.
123 - Admin console dashboard charts and reports for all users have been fully
124 migrated to the new, more reliable backend announced in 1.7.6.
125 - The maximum size of POST requests made through URLfetch has been increased
127 - Fixed an interaction issue between the Java MapReduce library and the Files
128 API which causes loss of data. If you are using the experimental Java

149 runtime, please use the --use_java6 flag when deploying your app. We encourage
150 you to move to Java7 as soon as possible.
151 - Billing enabled apps will no longer be subject to a $2.10 minimum weekly
152 spend. Instead, apps will only be charged for their actual usage.

180 not currently enforced, but will be part of the pricing model for the Search
181 API in a future release.
182 - The experimental Search API's ability to explicitly sort search results by
183 SortExpression.RANK_FIELD_NAME (i.e. _order_id) field in ascending order has
185 - Globally consistent indexes in the experimental Search API are now deprecated
186 and will be removed in the next release.
187 - Task Queue tasks may now be added and deleted asynchronously. This allows
188 applications to perform common task queue operations without blocking. This is
189 an experimental feature.

203 compute capacity equal to F4/B4 but with a maximum of 1G RAM instead
205 - The DataNucleus plugin has been upgraded to 2.1.2.
206 - The deprecated classes AddException, AddResponse, ListException,
207 ListIndexesException, ListIndexesRequest, ListIndexesResponse, ListRequest,
208 ListResponse, and RemoveException were removed from the Search API in the
209 SDK. If your app references any of these classes, you must deploy a new
210 version without these references before the next release of App Engine.
211 If you do not do this, your app may stop working in production.
212 - The Conversion API, which was decommissioned last release, has been removed
213 from the SDK. In a future release, the API will be removed from the
214 runtime and applications that attempt to use it may stop working.
215 Applications in production that import the library should be fixed as soon as

980 - Fixed a bug that caused appengine-jsr107cache-1.5.0.jar to be empty.
984 - Support for Backends which allow developers to create infrastructure
985 components that complement the existing dynamic apps that App Engine already
986 provides. Instances of a backend can maintain state, be addressed
987 individually, and are not subject to per-request time limits. They can also be
988 configured to consume more memory and CPU than ordinary dynamic instances.
989 - Task Queues support pull mode, allowing for more control over task queue work
990 rates. To use pull queues, include the 'mode' element in your queue.xml.
991 - Pull queues are supported by a REST API, allowing access from outside App
992 Engine. To use the REST API, you must also include a valid ACL section
993 specifying which users can lease tasks from the pull queue.
994 - Task Queue payload limits have been increased. Queues support 100KB per task.
995 Within App Engine, the new limit is 32 MB per batch of tasks. With the REST
996 API the limit is 1 MB per batch.
997 - HTTP request and response sizes have been increased to 32 MB.
998 - We have removed the rate quotas for requests, datastore operations,
999 memcache operations, and image API operations. Resource quotas still apply.

1001 Datastore as the default configuration option. Developers that still wish to
1002 use the Master/Slave configuration must explicitly choose this option at
1003 application creation time.
1004 - The Task Queue maximum configurable processing rate has been increased to
1006 - Modified Dashboard latency graphs to indicate they only include dynamic

1145 - The Always On feature allows applications to pay and keep 3 instances of their
1146 application always running, which can significantly reduce application
1148 - Developers can now enable Warmup Requests. By specifying a handler in an
1149 app's appengine-web.xml, App Engine will attempt to send a Warmup Request to
1150 initialize new instances before a user interacts with it. This can reduce the
1151 latency an end-user sees for initializing your application.
1152 - The Channel API is now available for all users.
1153 - Task Queue has been officially released, and is no longer an experimental
1154 feature. The API import paths that use 'labs' have been deprecated. Task queue
1155 storage will count towards an application's overall storage quota, and will
1156 thus be charged for.

1172 The size limit for incoming emails is still 10 MB.
1173 - Size and quantity limits on datastore batch get/put/delete operations have
1174 been removed. Individual entities are still limited to 1 MB, but your app may
1175 batch as many entities together for get/put/delete calls as the overall
1176 datastore deadline will allow for.
1177 - When iterating over query results, the datastore will now asynchronously
1178 prefetch results, reducing latency in many cases by 10-15%.
1179 - The Admin Console Blacklist page lists the top blacklist rejected visitors.
1180 - The automatic image thumbnailing service supports arbitrary crop sizes up to

1204 - In queue.xml, the maximum allowed bucket size is now 100.
1205 - Removed limits on zigzag merge-join queries. Therefore the error "The built-in
1206 indices are not efficient enough for this query and your data. Please add a
1207 composite index for this query." will no longer be thrown in most cases,
1208 enabling more types of queries without indexes.
1209 - The whitelist has been updated to include java.net.InetAddress and some
1210 interfaces and abstract classes in javax.xml.soap, including
1211 javax.xml.soap.SOAPMessage.
