Release a new version #6
Description
Since 0.5.2 we've updated librdkafka quite a few times, implemented new APIs, and fixed a number of bugs. We've been using main and haven't run into (many) major issues.
There are a number of APIs that we could still implement (transaction API comes to mind) and I don't like how we've merged the two Error types (librdkafka has both an error object and error codes which are returned by different generations of the API).
