Google has released version 1.5.1 of its App Engine software development kit (SDK) – the first point update to the 1.5 branch. Announced at the Google I/O developer conference, App Engine 1.5 added Go to the list of supported languages available to developers, albeit on an experimental basis.

The latest release of the SDK sees the open source (Apache License 2.0) ProtoRPC framework added as an official Python API and adds presence support to the Channel API. App Engine now includes a Geolocation Header (X-AppEngine-country) with every client request, attempting to identify the country from which the request originated. Support for WebP, Google's WebM-derived still picture format, has also been added to the Images API and the SDK can now emulate the High Replication Datastore (HRD) consistency model.

Further details about the update can be found in a post on the Google App Engine Blog and in the release notes for Python and for Java. Version 1.5.1 of the Google App Engine is available to download from Google Code, the company's project hosting site.
