Google App Engine for Java SDK 1.2.2 Released

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.
