[jira] [Commented] (KAFKA-461) remove support for format for magic byte 0 in 0.8

["Jay Kreps (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/KAFKA-461?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13434592#comment-13434592 ] 

Jay Kreps commented on KAFKA-461:
---------------------------------

I think the message format hasn't changed. Technically what we should do is change the request ids, but I think we decided not just to kind of "start fresh". Basically I don't think this would help since an old client can't make requests it won't be able to get any messages anyway.
