Hey everyone, Version 1.4.0 is officially released! Documentation will go live shortly. In the meantime, check out our blog post:
http://googleappengine.blogspot.com/2010/12/happy-holidays-from-app-engine-team-140.html Release notes are below: Python ------------ - 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. - Task Queue has been officially released, and is no longer an experimental feature. The API import paths that use 'labs' have been deprecated. Task queue storage will count towards an application's overall storage quota, and will thus be charged for. - The deadline for Task Queue and Cron requests has been raised to 10 minutes. Datastore and API deadlines within those requests remain unchanged. - For the Task Queue, developers can specify task retry_parameters in their queue.yaml. - Apps that have enabled billing are allowed up to 100 queues with the Task Queue API. - Metadata Queries on the datastore for datastore kinds, namespaces, and entity properties are available. - URLFetch allowed response size has been increased, up to 32 MB. Request size is still limited to 1 MB. - The request and response sizes for the Images API have been increased to 32 MB. - The total size of Memcache batch operations is increased to 32 MB. The 1 MB limit on individual Memcache objects still applies. - 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. - The automatic image thumbnailing service supports arbitrary crop sizes up to 1600px. - Overall average instance latency in the Admin Console is now a weighted average over QPS per instance. - The developer who uploaded an app version can download that version's code using the appcfg.py download_app command. This feature can be disabled on a per application basis in the admin console, under the 'Permissions' tab. Once disabled, code download for the application CANNOT be re-enabled. - 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. http://code.google.com/p/googleappengine/issues/detail?id=772 - Allow Django initialization to be moved to appengine_config.py to avoid Django version conflicts when mixing webapp.template with pure Django. http://code.google.com/p/googleappengine/issues/detail?id=1758 - Fixed an issue with OpenId over SSL. http://code.google.com/p/googleappengine/issues/detail?id=3393 - Fixed an issue on the dev_appserver where login/logout code didn't work using Python 2.6. http://code.google.com/p/googleappengine/issues/detail?id=3566 - Fixed an issue in the dev_appserver where get_serving_url did not work for transparent, cropped PNGs: http://code.google.com/p/googleappengine/issues/detail?id=3887 - Fixed an issue with the DatastoreFileStub. http://code.google.com/p/googleappengine/issues/detail?id=3895 Java --------- - 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 appengine-web.xml, 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. - Task Queue has been officially released, and is no longer an experimental feature.

Auto-updaters will also go live shortly. -- Ikai Lan Developer Programs Engineer, Google App Engine Blogger: http://googleappengine.blogspot.com Reddit: http://www.reddit.com/r/appengine Twitter: http://twitter.com/app_engine -- You received this message because you are subscribed to the Google Groups "Google App Engine" group.
