An app's queues are also subject to storage quota limits for their stored tasks,
i.e. those tasks that have been added to queues but not yet executed. This quota
is part of their total storage quota (including datastore and blobstore quota).
We allow an app to override the default portion of this quota available for
taskqueue storage (100M) with a top level field "total_storage_limit".

+
+ You can also just configure the Django version to be used by setting

+ main script):

App Engine Python SDK - Release Notes
+Version 1.4.0
+================================
+- 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 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.
+- 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 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.
+- 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 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
+
Version 1.3.8
==================================
- Builtin app.yaml handlers are available for common application functions,
such as appstats.
