I verified the release and ran the quickstarts and found that release 2.16 broke Apache Nemo runner which is also an issue for 2.17.0 RC #2. It is caused by a backwards incompatible change in ParDo.MultiOutput where getSideInputs return value was changed from List to Map as part of https://github.com/apache/beam/pull/9275. I filed https://issues.apache.org/jira/browse/BEAM-8989 to track the issue.
Should we re-add the method back in 2.17.0 renaming the newly added method to something else and also patch 2.16.0 with a minor change including the same fix (breaking 2.16.0 users who picked up the new method) or leave as is?
