Yesterday we released version 0.4 of the AdWords API Java Client Library. There are very few code changes and it still supports AdWords API v4 (except a a fix to the AdWordsService interface which was lacking a few methods used for quota management).
There are many improvements in the documentation and samples.
The javadoc for the library has been updated to reflect the new architecture, and now we ship samples showing how to use all the services, and the most useful methods in the API.
In addition to that, we now have a list of client libraries and samples available on the AdWords API Open Source Projects Wiki Page.
