Heya Andrew, To qualify the release I did the following:
* Ran the quickstart against both Docker images * Built the source and ran the quickstart against it (Java 17) * Ran the quickstart against the provided binaries (Java 17) * Did a few random walks through the Javadocs * Read through the Release Notes * Checked the workflow executions and the shared test executions +1 (binding) Thanks for running the release!
