Using version v1.102.1, I see some deprecated classes.

In the generated documentation I don't see any explanation to fix deprecated API usages. Besides, this project README is using deprecated code as examples:

https://github.com/googleapis/java-pubsub#creating-a-topic

The recent changelog mentions nothing:

https://github.com/googleapis/java-pubsub/blob/master/CHANGELOG.md

and the releases page brings nothing:

https://github.com/googleapis/java-pubsub/releases

Any guidance or an up-to-date example in the README and a mention in the changelog would be really helpful.
