Geolocation Header : App Engine now creates a “X-AppEngine-country” header for each client request. The header contains the result of an attempt to determine the country from which the request came.
Java and Python API extensions
- Channel API (presence support): Now you can configure the inbound service of an application to detect user presence. Thus, the application can respond to the connection / disconnection of the user from the channel.
- Images API (WebP support): Added support for WebP images. WebP is a new image format, which Google opened the code at the beginning of this year. The format provides lossy compression for images, while the size may be 39% smaller than the JPEG image of the same quality.
New API for Python
- ProtoRPC : ProtoRPC is an open source framework for creating well-defined and easy-to-use RPC web services.
Data store
- High Replication Datastore (HRD) in the SDK : SDK 1.5.1 for Java and Python can now emulate the consistency model HRD. This means that query results will not always reflect the latest data changes.
