            <title>[DOCS-7489] Modern drivers use write commands instead of OP_INSERT, OP_UPDATE, and OP_DELETE + getLastError</title>
                <link>https://jira.mongodb.org/browse/DOCS-7489</link>

                    <description>&lt;p&gt;This page:&lt;/p&gt;

&lt;p&gt;should mention that, starting with MongoDB 2.6 and maxWireVersion 3, modern drivers use write commands for acknowledged writes, instead of OP_INSERT, OP_UPDATE, and OP_DELETE + getLastError. The legacy op codes are not exactly &quot;deprecated&quot; since they are not scheduled for removal, and most drivers will use them for unacknowledged writes. But they are &quot;legacy&quot; or &quot;old-fashioned&quot;.&lt;/p&gt;</description>

&lt;p/&gt;
&lt;div id=&quot;syntaxplugin&quot; class=&quot;syntaxplugin&quot; style=&quot;border: 1px dashed #bbb; border-radius: 5px !important; overflow: auto; max-height: 30em;&quot;&gt;

		&lt;tbody &gt;
				&lt;tr id=&quot;syntaxplugin_code_and_gutter&quot;&gt;
						&lt;td  style=&quot; line-height: 1.4em !important; padding: 0em; vertical-align: top;&quot;&gt;
					&lt;pre style=&quot;font-size: 1em; margin: 0 10px;  margin-top: 10px;   margin-bottom: 10px;  width: auto; padding: 0;&quot;&gt;&lt;span style=&quot;color: black; font-family: &apos;Consolas&apos;, &apos;Bitstream Vera Sans Mono&apos;, &apos;Courier New&apos;, Courier, monospace !important;&quot;&gt;{insert: &quot;collection&quot;, documents: [ { ... } ] }&lt;/span&gt;&lt;/pre&gt;
			&lt;/td&gt;
		&lt;/tr&gt;
			&lt;/tbody&gt;
&lt;/table&gt;
&lt;/div&gt;
&lt;p/&gt;
&lt;p&gt;A third-party driver author pointed out to me on Twitter that you can&apos;t tell, from reading our wire protocol documentation, that the legacy opcodes are deprecated:&lt;/p&gt;
