// Starting in version 3, on quota violation, brokers send out responses before throttling.

|

// Starting in version 4, the client needs to issue a second request to join group

|

// Version 5 is bumped to apply group.instance.id to identify member across restarts.

|
|
// Version 6 is the first flexible version.
|

|
|
// Starting from version 7, the broker sends back the Protocol Type to the client (KIP-599).
