Most was expected, but this is pretty cool:

Geolocation Header: App Engine will now include a header with every client request that represents a best-effort attempt to identify the country from which the request originated. This header, “X-AppEngine-country,” can allow you to customize content based on the origin of the user. We hope this means no more “Select your location” drop downs for users!

Kind of underwhelming in my book. Where is SQL support (promised over a year ago in Google I/O 2010) and what about Java-Python feature parity?
