Google Java App Engine SDK 1.2.2 Released

Google has released a new version of the Google App Engine Java SDK, version 1.2.2. This is largely a bugfix release, but there are some interesting new features:

• 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.
• You can issue ancestor queries inside transactions.
