 # Deprecation Warnings
 
-There are several deprecations in the [MongoDB Node.js driver](http://npmjs.com/package/mongodb)
-that Mongoose users should be aware of. Mongoose provides options to work
-around these deprecation warnings, but you need to test whether these options
-cause any problems for your application. Please [report any issues on GitHub](https://github.com/Automattic/mongoose/issues/new).
-
-## Summary {#summary}
-
-To fix all deprecation warnings, follow the below steps:
-
-* Replace `rawResult: true` with `includeResultMetadata: true` in `findOneAndUpdate()`, `findOneAndReplace()`, `findOneAndDelete()` calls.
-
-Read below for more a more detailed description of each deprecation warning.
-
-## `rawResult` {#rawresult}
-
-As of Mongoose 7.4.0, the `rawResult` option to `findOneAndUpdate()` is deprecated.
-You should instead use the `includeResultMetadata` option, which the MongoDB Node.js driver's new option that replaces `rawResult`.
-
-```javascript
-// Replace this:
-const doc = await Test.findOneAndUpdate(
-  { name: 'Test' },
-  { name: 'Test Testerson' },
-  { rawResult: true }
-);
-
-// With this:
-const doc = await Test.findOneAndUpdate(
-  { name: 'Test' },
-  { name: 'Test Testerson' },
-  { includeResultMetadata: true }
-);
-```
-
-The `rawResult` option only affects Mongoose; the MongoDB Node.js driver still returns the full result metadata, Mongoose just parses out the raw document.
-The `includeResultMetadata` option also tells the MongoDB Node.js driver to only return the document, not the full `ModifyResult` object.
+There are no current deprecation warnings for Mongoose 9.x.
