61 certain percentage of traffic to a non-default application version. The
62 traffic is split by either cookie or IP address.
63 - Emails that are sent from Google Apps domains email addresses where the domain
64 has been set up to use DKIM will be signed: when an email was from a request
65 that originated on that app's domain or any time the email was sent from
66 an app adminstrator, including when that email is sent from a cron job or task
68 - In the Admin Console, you can now choose how much and how long you'd like to
69 store logs. All apps get 1G for free and eventually will be able to pay for
70 more, while the amount can be increased this release we won't start charging
71 for the additional capacity until the next release at the earliest.
72 - The instances screen in the Admin Console now has a button to shut down
74 - Each application log has a link to the instance that served the request. If
75 the instance is no longer serving requests, a message will be displayed.
76 - The TaskQueue API now supports the ability to tag a Pull Queue task. You may
77 then lease tasks by tag. This feature is experimental.
78 - Using Google Apps wildcard domain mappings, you can access alternate
79 versions of your app via a custom domain.

98 application quota, including Instance Hours, Datastore Ops and Datastore
100 - Developers can now specify how long a channel token will last until it
101 expires, with the default remaining two hours. Channel API quota is now
102 measured both in calls to create a channel and the number of hours of channel
103 time requested. The maximum hours of quota is the maximum number of channel
104 creation calls * 2, so free apps get 200 hours of requested channel token
106 - Task Queue API requests now include a X-Appengine-TaskETA header, that can be
107 used to measure task delivery latency.
108 - We have removed the deprecated labs version of the TaskQueue API.
109 - The default API deadlines for Blobstore API calls have been raised to 15s for
110 online and 30s for offline requests, up from 5s.

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

245 DatastoreNeedIndexException, many will now succeed. A small percentage will
247 - The SDK datastore viewer in the dev console now displays the number of "Write
248 Ops" for each entity. "Write Ops" are the total number of entity and index
249 writes that were required to create the entity.
250 - The Prospective Search API is available in Java for all applications. This API
251 is still experimental, so applications will be limited to a maximum of 1000
253 - We made a classloading improvement that we expect to help loading request
254 latencies for projects with large numbers of jars.
255 - Added support for the set_default_version flag to Appcfg.

540 initialize new instances before a user interacts with it. This can reduce the
541 latency an end-user sees for initializing your application.
542 - The Channel API is now available for all users.
543 - Task Queue has been officially released, and is no longer an experimental
