            <title>[KAFKA-385] Support exactly once delivery</title>
                <link>https://jira.mongodb.org/browse/KAFKA-385</link>
                <project id="16285" key="KAFKA">Kafka Connector</project>
                    <description>&lt;p&gt;Apache 3.x now supports exactly once delivery.&#160; The attached PR provides support but requires the minimum version that the connector will support to be 3.0. This will be a breaking change so this should be addressed with the work for version 2.0 of the connector&lt;/p&gt;
