97 - The deprecated classes AddException, AddResponse, ListException,
98 ListIndexesException, ListIndexesRequest, ListIndexesResponse, ListRequest,
99 ListResponse, and RemoveException were removed from the Search API in the
100 SDK. If your app references any of these classes, you must deploy a new
101 version without these references before the next release of App Engine.
102 If you do not do this, your app may stop working in production.
103 - The Conversion API, which was decommissioned last release, has been removed

601 - Developers can now specify how long a channel token will last until it
602 expires, with the default remaining two hours. Channel API quota is now
603 measured both in calls to create a channel and the number of hours of channel
604 time requested. The maximum hours of quota is the maximum number of channel
605 creation calls * 2, so free apps get 200 hours of requested channel token
607 - Task Queue API requests now include a X-Appengine-TaskETA header, that can be
608 used to measure task delivery latency.
609 - We have removed the deprecated labs version of the TaskQueue API.

1037 application always running, which can significantly reduce application
1039 - Developers can now enable Warmup Requests. By specifying a handler in an
1040 app's appengine-web.xml, App Engine will attempt to send a Warmup Request to
1041 initialize new instances before a user interacts with it. This can reduce the
1042 latency an end-user sees for initializing your application.
1043 - The Channel API is now available for all users.
1044 - Task Queue has been officially released, and is no longer an experimental
1045 feature. The API import paths that use 'labs' have been deprecated. Task queue

1063 The size limit for incoming emails is still 10 MB.
1064 - Size and quantity limits on datastore batch get/put/delete operations have
1065 been removed. Individual entities are still limited to 1 MB, but your app may
1066 batch as many entities together for get/put/delete calls as the overall
1067 datastore deadline will allow for.
1068 - When iterating over query results, the datastore will now asynchronously
1069 prefetch results, reducing latency in many cases by 10-15%.

1095 - In queue.xml, the maximum allowed bucket size is now 100.
1096 - Removed limits on zigzag merge-join queries. Therefore the error "The built-in
1097 indices are not efficient enough for this query and your data. Please add a
1098 composite index for this query." will no longer be thrown in most cases,
1099 enabling more types of queries without indexes.
1100 - The whitelist has been updated to include java.net.InetAddress and some
1101 interfaces and abstract classes in javax.xml.soap, including
1102 javax.xml.soap.SOAPMessage.
