Hi, I've just downloaded the latest Wireshark for Mac OS and am using it to view Kafka traffic.

The kafka protocol component is outdated though, as it's unable to deal with the Kafka API versions being used by my software. I see in the decoded packets the following info for each of the different Kafka API keys.

Kafka (OffsetCommit v4 Request)
    Length: 208
    [Response Frame: 1494]
    API Key: OffsetCommit (8)
    API Version: 4
        [Expert Info (Warning/Undecoded): Unsupported OffsetCommit version. Supports v0-3.]
            [Unsupported OffsetCommit version. Supports v0-3.]
            [Severity level: Warning]
            [Group: Undecoded]

Is there somewhere I can get an up-to-date Kafka protocol decoder?

thanks, Chris

The code has been done but patch not released to production.

    { KAFKA_OFFSET_COMMIT,       "OffsetCommit",      0, 3 },
    { KAFKA_OFFSET_COMMIT,                 "OffsetCommit",      0, 7 },

But builds of bleeding edge Wireshark are available for you to try this feature enhancement.

I just downloaded today's (17.4.2020) most recent bleeding edge version (3.3.0rc0-1044) and it doesn't seem to have support for this Kafka API protocol version. Was there a regression?

Version 3.2.3 (v3.2.3-0-gf39b50865a13) is able to display version 7.
What issue/error are you seeing?
