4 App Engine Java SDK - Release Notes
8 - This SDK will be the last release that can deploy Java 6 apps. In 1.8.2,
9 the SDK will only be compiled with the Java 7 compiler and the only target
10 runtime will be Java 7.
11 - The Task Queue async API is now a GA feature. The asynchronous methods
12 improve utilization by allowing your app to add, lease and delete multiple
14 - Cloud Console projects are now created by default whenever a new App Engine
15 app is created. This is a Preview feature.
16 - In an upcoming release the Experimental Google Cloud Storage API Functions
17 will be decommissioned. This API and its Experimental status is documented at
19 https://developers.google.com/appengine/docs/java/googlestorage/overview
20 - The Google Cloud Storage library will replace Google Cloud Storage API and is
21 now available as a Preview feature. More information can be found at
22 https://code.google.com/p/appengine-gcs-client/
23 - Bandwidth between App Engine and Google Cloud Storage is currently free of
24 charge (this may change in the future for certain levels of service).
25 - The Search API has graduated from Experimental to Preview. Apps that have
26 billing enabled can exceed the free quota levels and will be charged for
27 usage above these levels.
28 - Estimated number of search results will only be accurate if it is less than
29 or equal to the number of results requested. By default this can be
30 overridden by setting number_found_accuracy QueryOption in the Search API.
31 - Dates, atoms, and number fields can now be found by searching without a field
32 restriction in the Search API.
33 - A quoted empty string now returns atom fields with empty values for the
35 - Snippet and count functions are no longer allowed in sort expressions for the
37 - The Search API now has improved error messages for user errors and internal
39 - The Datastore now assigns scattered auto ids by default. Legacy auto ids
40 are still available via the 'auto_id_policy' option in appengine-web.xml.
41 - The Sockets API now allows client code to call get/set options against
42 sockets. Previously, calls raised "Not Implemented" exceptions. When
43 java.net.Socket.get<option>() is called, a mock value is returned, calls to
44 set<option>() will be silently ignored.
45 - Fixed an issue with the namespace not being displayed when a user attempts
46 to select a namespace in the Admin Console.
47 https://code.google.com/p/googleappengine/issues/detail?id=8164
48 - Fixed an issue in the Admin Console Logs page to correctly display 'Until'
49 instead of 'Since' for logs search criteria.
50 https://code.google.com/p/googleappengine/issues/detail?id=8659
54 - The Mail API now allows attachments with .zip and .gzip extensions as long as
55 the archives do not contain entries with blacklisted extensions.
56 http://code.google.com/p/googleappengine/issues/detail?id=5933
57 - New Billing Enabled apps will no longer default to an email quota of 20,000
58 per day. Instead, apps will need to file a request through the admin console
59 to get email quotas increased.
60 - Admin console dashboard charts and reports for all users have been fully
61 migrated to the new, more reliable backend announced in 1.7.6.
62 - The maximum size of POST requests made through URLfetch has been increased
64 - Fixed an interaction issue between the Java MapReduce library and the Files
65 API which causes loss of data. If you are using the experimental Java
66 MapReduce library, we strongly encourage you to update to the latest version
67 of the library in the public svn:
68 https://code.google.com/p/appengine-mapreduce/source/checkout
69 - Fixed an issue with the Mail API to prevent sending mail from a Google Apps
70 mail account that has been suspended.

77 - Fixed an issue with the Java SDK jar file being too large for Windows 64.
78 - Fixed a JAXBPermission.setDatatypeConverter permission issue in Java7 runtime.
82 - The Sockets API, which allows applications to make outgoing TCP connections
83 and send/receive UDP packets to the Internet using both IPv4 and IPv6, is now
84 available as an experimental feature.
85 - The Java runtime now defaults to Java7. If you still need to use the Java6
86 runtime, please use the --use_java6 flag when deploying your app. We encourage
87 you to move to Java7 as soon as possible.
88 - Billing enabled apps will no longer be subject to a $2.10 minimum weekly
89 spend. Instead, apps will only be charged for their actual usage.
90 - Fixed an issue where Datastore auto ids assigned by the scattered id
91 policy were too large to be represented as floating point numbers in the SDK.
92 - Fixed an issue with sort by doc_id not translating correctly causing
93 InvalidRequest errors in the Search API
94 https://code.google.com/p/googleappengine/issues/detail?id=8958
98 - Improvements to the App Engine billing system will be rolled out gradually to
100 - The application summary no longer displays the default version of a running
101 application, instead it lists the application as 'RUNNING'. In an upcoming
102 release applications will have multiple logical sub components, each of which
103 will have a default version. This UI update is meant to align with this
105 - Projection queries are now a fully supported GA feature.
106 - The XMPP API now has multi-JID getPresence(). This provides the ability to get
107 the availability of multiple users.
108 - The Java dev_appserver now allocates automatic ids using the 'scattered' id
109 allocation policy by default. For more information, please see "Specifying the
110 Automatic ID Allocation Policy":
111 https://developers.google.com/appengine/docs/java/tools/devserver#Using_the_
113 - Admin console dashboard charts and current load/errors reports will be moving
114 to a new, more reliable backend. The change will be gradually rolling to users
115 of admin console over the next few weeks.
116 - New Search API quotas are now displayed in the Admin Console. These quotas are
117 not currently enforced, but will be part of the pricing model for the Search
118 API in a future release.
119 - The experimental Search API's ability to explicitly sort search results by
120 SortExpression.RANK_FIELD_NAME (i.e. _order_id) field in ascending order has
122 - Globally consistent indexes in the experimental Search API are now deprecated
123 and will be removed in the next release.
124 - Task Queue tasks may now be added and deleted asynchronously. This allows
125 applications to perform common task queue operations without blocking. This is
126 an experimental feature.
127 - Fixed an issue which caused an incorrect server error message when setting the
128 default version on the admin console, though the version was set correctly.
129 - Fixed an issue that caused java.security.AccessControlException when creating

140 compute capacity equal to F4/B4 but with a maximum of 1G RAM instead
142 - The DataNucleus plugin has been upgraded to 2.1.2.
143 - The deprecated classes AddException, AddResponse, ListException,
144 ListIndexesException, ListIndexesRequest, ListIndexesResponse, ListRequest,
145 ListResponse, and RemoveException were removed from the Search API in the
146 SDK. If your app references any of these classes, you must deploy a new
147 version without these references before the next release of App Engine.
148 If you do not do this, your app may stop working in production.
149 - The Conversion API, which was decommissioned last release, has been removed
150 from the SDK. In a future release, the API will be removed from the
151 runtime and applications that attempt to use it may stop working.
152 Applications in production that import the library should be fixed as soon as
154 - We are making Java 7 available as an experimental feature. We strongly

609 traffic is split by either cookie or IP address.
610 - Emails that are sent from Google Apps domains email addresses where the domain
611 has been set up to use DKIM will be signed: when an email was from a request
612 that originated on that app's domain or any time the email was sent from
613 an app adminstrator, including when that email is sent from a cron job or task
615 - In the Admin Console, you can now choose how much and how long you'd like to
616 store logs. All apps get 1G for free and eventually will be able to pay for

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

795 Ops" for each entity. "Write Ops" are the total number of entity and index
796 writes that were required to create the entity.
797 - The Prospective Search API is available in Java for all applications. This API
798 is still experimental, so applications will be limited to a maximum of 1000
800 - We made a classloading improvement that we expect to help loading request
801 latencies for projects with large numbers of jars.
802 - Added support for the set_default_version flag to Appcfg.

1088 latency an end-user sees for initializing your application.
1089 - The Channel API is now available for all users.
1090 - Task Queue has been officially released, and is no longer an experimental
1091 feature. The API import paths that use 'labs' have been deprecated. Task queue

1112 batch as many entities together for get/put/delete calls as the overall
1113 datastore deadline will allow for.
1114 - When iterating over query results, the datastore will now asynchronously
1115 prefetch results, reducing latency in many cases by 10-15%.

1141 - In queue.xml, the maximum allowed bucket size is now 100.
1142 - Removed limits on zigzag merge-join queries. Therefore the error "The built-in
1143 indices are not efficient enough for this query and your data. Please add a
1144 composite index for this query." will no longer be thrown in most cases,
1145 enabling more types of queries without indexes.
