            <title>[SERVER-41873] Remove most uses of &apos;oplogreplay&apos; flag in 4.5</title>
                <link>https://jira.mongodb.org/browse/SERVER-41873</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;The `oplogreplay` flag was deprecated for 4.4 nodes in&#160;&lt;a href=&quot;https://jira.mongodb.org/browse/SERVER-36186&quot; class=&quot;external-link&quot; rel=&quot;nofollow&quot;&gt;SERVER-36186&lt;/a&gt; but some code for serialization/deserialization and replication was kept to remain compatible with 4.2 nodes. Uses of `oplogreplay` can now be safely removed for 4.6.&lt;/p&gt;

&lt;p&gt;`oplogreplay` flag should still be permitted to remain compatible with drivers.&lt;/p&gt;</description>

&lt;p&gt;Message: &lt;a href=&quot;https://jira.mongodb.org/browse/SERVER-41873&quot; title=&quot;Remove most uses of &amp;#39;oplogreplay&amp;#39; flag in 4.5&quot; class=&quot;issue-link&quot; data-issue-key=&quot;SERVER-41873&quot;&gt;&lt;del&gt;SERVER-41873&lt;/del&gt;&lt;/a&gt; Remove most remaining uses of &apos;oplogReplay&apos; flag&lt;/p&gt;

&lt;p&gt;Starting in 4.4, this flag is accepted by the server but&lt;br/&gt;
does not affect how the query is executed. However, there&lt;br/&gt;
were several places in the code base where &apos;oplogReplay&apos;&lt;br/&gt;
needed to be handled due to the possibility of a mixed&lt;br/&gt;
version 4.2/4.4 cluster. This logic can now be removed,&lt;br/&gt;
since a 4.6 node need not be compatible with 4.2.&lt;/p&gt;

&lt;p&gt;In order to avoid breaking old drivers, the &apos;oplogReplay&apos;&lt;br/&gt;
find command option and OP_QUERY flag bit will continue to&lt;br/&gt;
be accepted but ignored.&lt;br/&gt;
Branch: master&lt;br/&gt;

We&apos;re using 4.3 Required so we remember to update this later.&lt;/p&gt;</comment>
