Greetings App Engine developers! We're pleased to announced the availability of a new Java SDK, available for download here. This is largely a bugfix release, but there are a few new features we think you'll be excited to get your hands on:

  • The appcfg upload tool includes proxy support.

  • JDO and JPA support an extension that lets you mark individual fields as "unindexed."

  • At long last, the dev appserver has a data viewer. Start your app locally and point your browser to http://localhost:8080/_ah/admin to check it out.

  • The local datastore now has the same transaction behavior as the production datastore (more info: http://code.google.com/p/googleappengine/issues/detail?id=1411)

  • You can issue ancestor queries inside transactions.



For a full list of features, see the release notes.
