understood by brokers or version 2.5 or higher, so you must upgrade your kafka cluster to get the stronger semantics. Otherwise, you can just pass
in <code>new ConsumerGroupMetadata(consumerGroupId)</code> to work with older brokers. See <a href="https://cwiki.apache.org/confluence/x/zJONCg">KIP-732</a> for more details.

The Connect <code>internal.key.converter</code> and <code>internal.value.converter</code> properties have been completely <a href="https://cwiki.apache.org/confluence/x/2YDOCg">removed</a>.
The use of these Connect worker properties has been deprecated since version 2.0.0.
Workers are now hardcoded to use the JSON converter with <code>schemas.enable</code> set to <code>false</code>. If your cluster has been using
a different internal key or value converter, you can follow the migration steps outlined in <a href="https://cwiki.apache.org/confluence/x/2YDOCg">KIP-738</a>
to safely upgrade your Connect cluster to 3.0.

<li> The Connect-based MirrorMaker (MM2) includes changes to support <code>IdentityReplicationPolicy</code>, enabling replication without renaming topics.
The existing <code>DefaultReplicationPolicy</code> is still used by default, but identity replication can be enabled via the
<code>replication.policy</code> configuration property. This is especially useful for users migrating from the older MirrorMaker (MM1), or for
