- Developers can now specify how long a channel token will last until it expires, with the default remaining two hours. Channel API quota is now measured both in calls to create a channel and the number of hours of channel time requested. The maximum hours of quota is the maximum number of channel creation calls * 2, so free apps get 200 hours of requested channel token time.

The tool is not yet generally available. If you are interested in being an early adopter please fill out this form:
- Fixed an issue in the Channel API where jsapi was not served with the correct MIME type.

Instances of a backend can maintain state, be addressed individually, and are not subject to per-request time limits. They can also be configured to consume more memory and CPU than ordinary dynamic instances.
- Task Queues support pull mode, allowing for more control over task queue work rates. To use pull queues, include the 'mode' argument in your queue.yaml.

Version 1.4.0 - December 02, 2010- The Always On feature allows applications to pay and keep 3 instances of their application always running, which can significantly reduce application latency.
- Developers can now enable Warmup Requests. By specifying a handler in an app's app.yaml, App Engine will attempt to send a Warmup Request to initialize new instances before a user interacts with it. This can reduce the latency an end-user sees for initializing your application.
- The Channel API is now available for all users.

- The attachment size for outgoing emails has been increased from 1 MB to 10 MB. The size limit for incoming emails is still 10 MB.
- Size and quantity limits on datastore batch get/put/delete operations have been removed. Individual entities are still limited to 1 MB, but your app may batch as many entities together for get/put/delete calls as the overall datastore deadline will allow for.
- When iterating over query results, the datastore will now asynchronously prefetch results, reducing latency in many cases by 10-15%.
- The Admin Console Blacklist page lists the top blacklist rejected visitors.

- Fixed an issue where custom Admin Console pages did not work for Google Apps for your Domain users.
- In the Python runtime, an instance is killed and restarted when a request handler hits DeadlineExceededError. This should fix an issue related to intermittent SystemErrors using Django.
