Just a few (potential) improvements to Google's cloud-based services. App Engine version 1.6.5 is the fourth release this year, and according to the Google Developer Blog, the improvements include changes to Datastore, the Images API, and a few other things. The team has added projection quereies to the Datastore. Projection queries allow for the querying of specific properties within an entity. THere are some rules and limitations to this type of query, which you can read about here.
