+<h3 id="copy-schema-options-in-schema-prototype-add"><a href="#copy-schema-options-in-schema-prototype-add">Copy Schema options in <code>Schema.prototype.add()</code></a></h3>
+
+Mongoose now copies user defined schema options when adding one schema to another.
+For example, `childSchema` below will get `baseSchema`'s `id` and `toJSON` options.
+
+```javascript
+const baseSchema = new Schema({ created: Date }, { id: true, toJSON: { virtuals: true } });
+const childSchema = new Schema([baseSchema, { name: String }]);
+
+childSchema.options.toJSON; // { virtuals: true } in Mongoose 7. undefined in Mongoose 6.
+```
+
+This applies both when creating a new schema using an array of schemas, as well as when calling `add()` as follows.
+
+```javascript
+childSchema.add(new Schema({}, { toObject: { virtuals: true } }));
+
+childSchema.options.toObject; // { virtuals: true } in Mongoose 7. undefined in Mongoose 6.
+```

 <h3 id="objectid-bsontype-now-has-lowercase-d"><a href="#objectid-bsontype-now-has-lowercase-d">ObjectId bsontype now has lowercase d</a></h3>
 
 The internal `_bsontype` property on ObjectIds is equal to `'ObjectId'` in Mongoose 7, as opposed to `'ObjectID'` in Mongoose 6.
