App Engine Python SDK - Release Notes

Version 1.5.2
=============================
- You can now specify the minimum pending latency for instances and the maximum
  number of idle instances for your application in the Admin Console.
- The datastore now never requires an exploding index.
    http://code.google.com/appengine/docs/python/datastore/queries.html#Big_Entities_and_Exploding_Indexes
- The SDK will now never suggest indexes with the same property repeated, as
  such indexes are likely to be exploding indexes.
- The SDK now supports multiple concurrent transactions.
- Datastore stats are now available on a per-namespace basis.
- The queue details page in the Admin Console now contains request header
  details, previous run information, and a task payload viewer.
- You can modify the lease on a task leased from a pull queue using the
  modify_task_lease() method.
- Pull Task maximum size has been increased to 1MB.
- You can now update the number of available backend instances without needing
  to first stop the backend using the "backend configure" appcfg.py directive.
- You can now set the "References" and "In-Reply-To" headers with the Mail API.
    http://code.google.com/p/googleappengine/issues/detail?id=2802
- The SDK "application" environment variable will now be prefixed with dev~.
  The new preferred way of retrieving your app id is to use
  appidentity.get_application_id(). The --default_partition flag can be used
  for applications whose code relied on a specific environment variable.
- In the Deferred API, defer() now accepts the _target parameter.
- Added a to_dict() function to db.py which converts a model to a dictionary.
- Added a get_original_metadata() method to the Images API to extract EXIF
  information from images.
    http://code.google.com/p/googleappengine/issues/detail?id=4133
- Added an @transactional decorator to db.py for functions that should
  always be run in a transaction.
- Fixed an issue in the SDK where the Deferred API did not work when using
  the --backends flag.
    http://code.google.com/p/googleappengine/issues/detail?id=5072

Version 1.5.1
============================
- ProtoRPC is a new experimental library that provides a simple method for
  creating a well-defined and easy-to-use web-based RPC service.
- The development server's datastore implementation now contains logic that
  closely replicates the consistency guarantees of the High Replication
  datastore. To use, run the dev_appserver with the flag --high_replication set
  to True.
- All user request have an X-AppEngine-Country header which contains the
  ISO-3166-1 alpha-2 country code for the user, based on the IP address of the
  client request.
- The Channel API can now provide user presence, this can be configured by
  adding channel_presence to the list of inbound services for your application.
- The Images API now supports the WebP format. Due to limitations in PIL, the
  SDK does not support the WebP format.
- You can switch the timezone for App Engine logs in the Admin Console.
  http://code.google.com/p/googleappengine/issues/detail?id=734
- Fixed an issue in the SDK where leased tasks had the POST method. They now
  have a PULL method.
- Fixed an issue where the Channel API didn't work with non-default versions of
  applications using the High Replication datastore.
- When displaying corrupt data in the Admin Console dataviewer, a useful error
  will be displayed, instead of a 500.
  http://code.google.com/p/googleappengine/issues/detail?id=4945

Version 1.5.0
==============================
- Support for Backends which allow developers to create infrastructure
  components that complement the existing dynamic apps that App Engine already
  provides. 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.
- Pull queues are supported by a REST API, allowing access from outside App
  Engine. To use the REST API, you must also include a valid ACL section
  specifying which users can lease tasks from the pull queue.
- Task Queue payload limits have been increased. Queues support 100KB per task.
  Within App Engine, the new limit is 32 MB per batch of tasks. With the REST
  API the limit is 1 MB per batch.
- HTTP request and response sizes have been increased to 32 MB.
- We have removed the rate quotas for requests, datastore operations,
  memcache operations, and image API operations. Resource quotas still apply.
- When creating new applications, developers will now see the High Replication
  Datastore as the default configuration option.  Developers that still wish to
  use the Master/Slave configuration must explicitly choose this option at
  application creation time.
- The Task Queue maximum configurable processing rate has been increased to
  500/s.
- We have added two restrictions to the Mail API to improve the reliability
  of the service for all applications.
  - Emails must be sent from email accounts managed by Google (either Gmail or
    a domain signed up for Google Apps).
  - Reduced the number of free recipients per day from 2000 to 100 for new
    applications.
- All application Owners, as listed in the Admin Console, can download the app's
  code, unless code download is disabled for the application.
- Added db.py support for making calls to the datastore asynchronously.
  Available functions are get_async(), put_async(), delete_async(),
  allocate_ids_async(). Call get_result on the return value of asynchronous	
  datastore functions to block on the call.
- Metadata queries can now get all namespaces, kinds, and properties in a given
  range.
- The Testbed API now supports the Channel API.
- Users can provide Django settings to be loaded in webapp's django_setup.
- Modified Dashboard latency graphs to indicate they only include dynamic
  requests.
- Fixed an issue where metadata queries did not support unicode characters.
- Fixed an issue where HTTP headers could contain new line characters.
- A warning message is shown when the Python version used to run the SDK is
  different than the Python version used in production.
- Fixed an issue with Federated Users causing the Admin Console dataviewer to
  fail.

    http://code.google.com/p/googleappengine/issues/detail?id=3931


Version 1.4.1
================================
- During application creation, developers can choose between two Datastore
  configurations: High Replication or Master/Slave.
    http://code.google.com/appengine/docs/python/datastore/hr/#Selecting_a_Datastore
- You can set your application's datastore to read-only mode in the Admin
  Console. Any writes attempted while the app is set to read-only will throw a
  CapabilityDisabledError. This feature can be helpful for migrating or copying
  data between two applications.
    http://code.google.com/appengine/docs/adminconsole/applicationsettings.html#Disable_Datastore_Writes
- The Datastore Admin tool has been updated to allow copying of one app's
  datastore to another. The destination app must have the Remote API enabled.
    http://code.google.com/appengine/docs/adminconsole/datastoreadmin.html
- The deadline for offline URL Fetch API requests for Python and Java have been
  increased to a maximum of 10 minutes. The default deadline for offline
  URL Fetch requests remains the same.
- Fixed an issue where an AttributeError was occasionally thrown on a datastore
  query.
    http://code.google.com/p/googleappengine/issues/detail?id=4196

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 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

Version 1.3.8
==================================
- Builtin app.yaml handlers are available for common application functions,
  such as appstats.
    http://code.google.com/appengine/docs/python/config/appconfig.html#Builtin_Handlers
- The Admin Console now provides an experimental tool to delete all entities in
  the datastore or all entities of a given type. This is available only if
  enabled using the datastore_admin builtin. Deleting entities will count
  against application quota.
    http://code.google.com/appengine/docs/python/datastore/creatinggettinganddeletingdata.html#Deleting_Entities_in_Bulk
- You can run task queue tasks immediately from the Admin Console.
- You can now specify the quality of JPEG images via the Image API's
  execute_transforms function. Available in production only.
- Support for login of multiple Google accounts within an app, and longer login
  sessions. For more information see:
    http://www.google.com/support/accounts/bin/answer.py?answer=181599
- In queue.yaml, the maximum allowed bucket size is now 100.
- Precompilation is now enabled by default. To disable, use the
  --no_precompilation flag when updating your app.
- BlobInfo now has an open() method that returns a BlobReader.
- BlobReader now accepts a BlobInfo.
- Removed limits on zigzag merge-join queries. Therefore the error "The built-in
  indices are not efficient enough for this query and your data. Please add a
  composite index for this query." will no longer be thrown in most cases,
  enabling more types of queries without indexes.
- Fixed an issue with task queue tasks not running on the dev_appserver when
  using Python 2.6.
- Fixed an issue on the dev_appserver where auto task running wasn't working for
  BulkAdd.
- Fixed an issue reserving App Ids by owners of similarly-named mails accounts
  containing periods, multiple cases, and googlemail.com address.
    http://code.google.com/p/googleappengine/issues/detail?id=1196
- Fixed an issue on the development server where PNGs were being returned as
  JPEGs.
    http://code.google.com/p/googleappengine/issues/detail?id=3661
