http://code.google.com/p/googleappengine/downloads/list

See release notes below: notice ProtoRPC, Channel API presence, WebP
support, X-AppEngine-Country header and a lot of bug fixes.

Happy testing!

Python
============================
- 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.

- 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.
