4 App Engine Java SDK - Release Notes
8 - New instance classes F4_1G and B4_1G are now available. These instances have
9 compute capacity equal to F4/B4 but with a maximum of 1G RAM instead
11 - The DataNucleus plugin has been upgraded to 2.1.2.
12 - The deprecated classes AddException, AddResponse, ListException,
13 ListIndexesException, ListIndexesRequest, ListIndexesResponse, ListRequest,
14 ListResponse, and RemoveException were removed from the Search API in the
15 SDK. If your app references any of these classes, you must deploy a new
16 version without these references before the next release of App Engine.
17 If you do not do this, your app may stop working in production.
18 - The Conversion API, which was decommissioned last release, has been removed
19 from the SDK. In a future release, the API will be removed from the
20 runtime and applications that attempt to use it may stop working.

477 certain percentage of traffic to a non-default application version. The
478 traffic is split by either cookie or IP address.
479 - Emails that are sent from Google Apps domains email addresses where the domain
480 has been set up to use DKIM will be signed: when an email was from a request
481 that originated on that app's domain or any time the email was sent from
482 an app adminstrator, including when that email is sent from a cron job or task
484 - In the Admin Console, you can now choose how much and how long you'd like to
485 store logs. All apps get 1G for free and eventually will be able to pay for
486 more, while the amount can be increased this release we won't start charging
487 for the additional capacity until the next release at the earliest.
488 - The instances screen in the Admin Console now has a button to shut down
490 - Each application log has a link to the instance that served the request. If
491 the instance is no longer serving requests, a message will be displayed.
492 - The TaskQueue API now supports the ability to tag a Pull Queue task. You may
493 then lease tasks by tag. This feature is experimental.

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

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

952 application always running, which can significantly reduce application
954 - Developers can now enable Warmup Requests. By specifying a handler in an
955 app's appengine-web.xml, App Engine will attempt to send a Warmup Request to
956 initialize new instances before a user interacts with it. This can reduce the
957 latency an end-user sees for initializing your application.
958 - The Channel API is now available for all users.
959 - Task Queue has been officially released, and is no longer an experimental

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