  - Bugfix: Fixed a bug that broke using `org.apache.kafka.common.serialization.ByteArraySerializer` as the `value_serializer`

## 7.0.3
  - Bugfix: Sends are now retried until successful. Previously, failed transmissions to Kafka
    could have been lost by the KafkaProducer library. Now we verify transmission explicitly.
    This changes the default 'retry' from 0 to retry-forever. It was a bug that we defaulted
    to a retry count of 0.

   with inputs because inputs by default are single threaded. This makes it a bad
   first user experience. Plain codec is a much better default.
