&lt;p&gt;Message: &lt;a href=&quot;https://jira.mongodb.org/browse/CDRIVER-4305&quot; title=&quot;ChangeStream Spec: fullDocument field in ChangeStreamOptions should be an optional to handle &amp;quot;default&amp;quot; case.&quot; class=&quot;issue-link&quot; data-issue-key=&quot;CDRIVER-4305&quot;&gt;&lt;del&gt;CDRIVER-4305&lt;/del&gt;&lt;/a&gt;: &apos;fullDocument&apos; may be null/omitted (#1010)&lt;/p&gt;

&lt;p&gt;This commit implements &lt;a href=&quot;https://jira.mongodb.org/browse/CDRIVER-4305&quot; title=&quot;ChangeStream Spec: fullDocument field in ChangeStreamOptions should be an optional to handle &amp;quot;default&amp;quot; case.&quot; class=&quot;issue-link&quot; data-issue-key=&quot;CDRIVER-4305&quot;&gt;&lt;del&gt;CDRIVER-4305&lt;/del&gt;&lt;/a&gt;, which allows fullDocument to be&lt;br/&gt;
NULL equivalent to a literal &quot;default&quot; string. This is permitted in&lt;br/&gt;
server 3.6+, and this change makes that the preferred and default&lt;br/&gt;
behavior.&lt;/p&gt;

&lt;p&gt;This driver already requires 3.6 or newer (as per minWireVersion)&lt;br/&gt;
Branch: master&lt;br/&gt;

We don&apos;t yet have language tickets for DRIVERS-1713, but I&apos;ll add a relationship to the language ticket for &lt;a href=&quot;https://jira.mongodb.org/browse/DRIVERS-1995&quot; title=&quot;Do not error when parsing change stream event documents&quot; class=&quot;issue-link&quot; data-issue-key=&quot;DRIVERS-1995&quot;&gt;DRIVERS-1995&lt;/a&gt;.&lt;/p&gt;</comment>

                            <customfieldvalue>&lt;p&gt;&lt;a href=&quot;https://jira.mongodb.org/browse/DRIVERS-2231&quot; title=&quot;ChangeStream Spec: fullDocument field in ChangeStreamOptions should be an optional to handle &amp;quot;default&amp;quot; case.&quot; class=&quot;issue-link&quot; data-issue-key=&quot;DRIVERS-2231&quot;&gt;&lt;del&gt;DRIVERS-2231&lt;/del&gt;&lt;/a&gt;:&lt;br/&gt;
Currently, the ChangeStream spec defines the fullDocument field in ChangeStreamOptions as a String that defaults to the string literal &quot;default&quot;. As of server version 3.6, sending &quot;default&quot; and sending no fullDocument field have identical behavior, so fullDocument should be defined as an Optional&amp;lt;String&amp;gt; to avoid using the &quot;default&quot; string literal.&lt;/p&gt;

&lt;p&gt;Drivers should sync legacy change streams tests to &lt;a href=&quot;https://github.com/mongodb/specifications/commit/31edce69d0fed2151a08c66204b7b60afcd6ab9b&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;mongodb/specifications@31edce6&lt;/a&gt; and legacy retryable reads tests to &lt;a href=&quot;https://github.com/mongodb/specifications/commit/006a4f1a363e3d03f7169b85e0b5c53b61946d83&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;mongodb/specifications@006a4f1&lt;/a&gt; .&lt;/p&gt;</customfieldvalue>
