Hey everyone,
Prerelease SDK 1.5.5 is now available for download! You can get it here:
Python:
http://code.google.com/p/googleappengine/downloads/detail?name=google_appengine_prerelease-1.5.5.zip
Java:

We provide prerelease SDKs as previews for things to come. New features
should not work in production yet, and documentation is typically still a
work in progress. Release notes are below as well as in the prerelease
packages:
Python
===
- Python 2.7 is now available as an experimental runtime for all
applications
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.
- We have released an experimental utility, available in the Admin Console,
to
assist in migrating your application to the High Replication datastore.
This
utility allows you to copy the bulk of your data in the background, while
the
source application is still serving. You then need a brief read-only
period to
migrate your application data while you copy the data that has changed
from
the time the original copy started.
- We have increased the number of files you can upload with your application
from 3,000 to 10,000.
- We have increased the size limit for a single file uploaded to App Engine
from
10MB to 32MB.
- We have increased the Frontend request deadline from 30 seconds to 60
seconds.
- We have increased the URLFetch maximum deadline from 10 seconds to 60
seconds.
- We have increased the URLFetch Post payload from 1MB to 5MB.
- App Engine now supports Cross Group (XG) transactions with the High
Replication Datastore, which allow you to perform transactions across
multiple entity groups.
- We have released an experimental API that can write to Google Storage for
Developers directly from App Engine.
- We have added a graph to the admin console that displays the number of
instances for which you will be billed.
- In the XMPP API, get_presence() is deprecated in favor of using the
inbound
presence handlers documented in
http://code.google.com/appengine/docs/python/xmpp/overview.html#Handling_User_Presence
.
- The Task Queue API 'target' parameter now accepts a new value,
taskqueue.DEFAULT_APP_VERSION, which will send the task to the default
frontend version, rather than the version or backend where the 'add'
method is
being called.
- In the URLFetch API, make_fetch_call() now returns an RPC object.
- Fixed an issue in the Admin Console where the "Run Now" button did not
work
for tasks with a '-' in the name.
- Fixed an issue where the SDK did not decode Base64 encoded blobs.
- Fixed an issue to provide a better error message when using the Mail API
to
send email to an invalid user address.
- Fixed an issue in the SDK where a skip_files entry caused an ImportError
when
the library was located elsewhere in the PYTHONPATH.
- Fixed an issue in the SDK index viewer where the arrows indicating whether
a
query was ascending or descending were not properly rendered.
- Fixed an issue where httplib did not support the deadline argument for
URLFetch calls.

- Fixed an issue where you could not schedule a cron job to run every 100
minutes.
http://code.google.com/p/googleappengine/issues/detail?id=5243
- Fixed an issue in the SDK where failed tasks retried immediately instead
of
waiting for 30 seconds.
http://code.google.com/p/googleappengine/issues/detail?id=5587
- Fixed an issue making it possible to modify request headers using the
deferred
library.
