Important: In this release, we’ve patched a bug that causes the potential for incorrect results from certain queries that have had joins reordered in specific ways, in combination with certain data. A small percentage of queries are affected, but due to the complexity of the conditions that trigger the bug, it is not possible to predict which queries will be affected and thus we recommend that _all_ customers upgrade all clusters.

Add Varbinary handling to Kafka Protobuf deserializer.
