rates. This is a Preview feature. For more information please see:
- Push-to-Deploy is now available to all developers. This Preview feature makes
it even easier to deploy PHP apps.
- no longer requires the -R parameter to deploy PHP applications.
- The function libxml_disable_entity_loader() is now disabled by default for

stored on Google Cloud Storage.
- Fixed an issue with the dev_appserver on Windows where the PHP interpreter
was not passed a required environment variable.

Version 1.8.1
- The Task Queue async API is now a GA feature. The asynchronous methods
improve utilization by allowing your app to add, lease and delete multiple
tasks in parallel.
- Cloud Console projects are now created by default whenever a new App Engine
app is created. This is a Preview feature.
- In an upcoming release the Experimental Google Cloud Storage API Functions
will be decommissioned. This API and its Experimental status is documented at
the following link:
- The Google Cloud Storage library will replace Google Cloud Storage API and is
now available as a Preview feature. More information can be found at
- Bandwidth between App Engine and Google Cloud Storage is currently free of
charge (this may change in the future for certain levels of service).
- The Search API has graduated from Experimental to Preview. Apps that have
billing enabled can exceed the free quota levels and will be charged for
usage above these levels.
- Estimated number of search results will only be accurate if it is less than
or equal to the number of results requested. By default this can be
overridden by setting number_found_accuracy QueryOption in the Search API.

restriction in the Search API.

complete the initial setup steps, you will be ready to deploy apps with the
same ease you push code to a git repository using
"% git push appengine master". This is a Limited Preview feature. You may
request access via the following link:
- The Datastore now assigns scattered auto ids by default. Legacy auto ids
are still available via the 'auto_id_policy' option in app.yaml.
- The Sockets API now allows client code to call get/set options against
sockets. Previously, calls raised "Not Implemented" exceptions. For supported
options, calls to getsockopt will return a mock value and calls to setsockopt
will be silently ignored. Errors will continue to be raised for unsupported
options. The currently supported options are: SO_KEEPALIVE, SO_DEBUG,
- Updated skip_files documentation to reflect the new default.
- The ndb library now supports distinct queries. This is a Preview feature.

the google_app_engine.allow_include_gs_buckets ini setting.

This means that many standard filesystem functions such as is_file(),
is_readable(), is_writeable(), filesize(), etc now work with Cloud Storage
- Honor the default_stream_context for Google Cloud Storage streams when
writing new objects.

complete the initial setup steps, you will be ready to deploy apps with the
same ease you push code to a git repository using
"% git push appengine master". This is a Limited Preview feature. You may
request access via the following link:
- Updated skip_files documentation to reflect the new default.
- Removed the NotAllowedError, RedirectTooLongError, and UserNotFoundError
exception classes from the Users API. Their use is replaced by throwing a
UsersException or InvalidArgumentException as appropriate.
- Removed the Capability API.
- Fixed an issue with Google Cloud Storage objects not being compatible across
various APIs on the dev_appserver.

without these references before the next release of App Engine. If you do not
do this, your app may stop working in production.

that originated on that app's domain or any time the email was sent from
an app adminstrator, including when that email is sent from a cron job or task
queue request.
- In the Admin Console, you can now choose how much and how long you'd like to

for the additional capacity until the next release at the earliest.
- The instances screen in the Admin Console now has a button to shut down
a specific instance.

- The Admin Console Datastore Admin has added experimental backup and restore
functionality. The job occurs within your application and counts against your
application quota, including Instance Hours, Datastore Ops and Datastore
- 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

using the High Replication Datastore. To upload your app to the Python 2.7
runtime, change the runtime argument in your app.yaml to python27. Note that

to your datastore write rate (as opposed to your datastore size, which is how
the current version behaves). 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

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.

data between two applications.
- 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.

increased to a maximum of 10 minutes. The default deadline for offline
URL Fetch requests remains the same.

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
- 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

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.

prefetch results, reducing latency in many cases by 10-15%.

- The automatic image thumbnailing service supports arbitrary crop sizes up to
- Overall average instance latency in the Admin Console is now a weighted
average over QPS per instance.
