            <title>[SERVER-46783] New accumulators and MR operators should be FCV 4.4 only</title>
                <link>https://jira.mongodb.org/browse/SERVER-46783</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;$accumulator should be available only when FCV is&#160;kFullyUpgradedTo44.&#160; We need to extend the REGISTER_ACCUMULATOR macro, similar to&#160;REGISTER_EXPRESSION_WITH_MIN_VERSION.&lt;/p&gt;

&lt;p&gt;We can also mark $_internalJsReduce and $_internalJsEmit as 4.4 only.&#160; These internal operators are part of the new mapReduce implementation, and mongos should only produce them on FCV 4.4.&lt;/p&gt;</description>
