Thanks.

Ok, i have some questions.

First questions about supported and unsupported packet versions.
Kafka packets have "API Version" field. I will try to show problem with 
example.
Latest version of kafka server supports Produce Request/Response of 
version 0, 1, 2.
Dissector parses correctly only 0 and 1. For Produce Response it 
generates incorrect proto tree because this version has new field in 
middle of packet.

Current version parses incorrectly and doesn't add expert info.

- Should dissector rejects packets with unsupported versions and add 
export info?
- Or should dissector parse incorrectly (or correctly if format was not 
changed) and always add expert info about "Unsupported version: May be 
parsed incorrectly"?

I like second solution.
