+There are several backwards-breaking changes you should be aware of when migrating from Mongoose 7.x to Mongoose 8.x.
 
 If you're still on Mongoose 6.x or earlier, please read the [Mongoose 6.x to 7.x migration guide](migrating_to_7.html) and upgrade to Mongoose 7.x first before upgrading to Mongoose 8.
 
+We also recommend reviewing the [MongoDB Node.js driver's release notes for v6.0.0](https://github.com/mongodb/node-mongodb-native/releases/tag/v6.0.0) before upgrading to Mongoose 8.

+Mongoose 8 uses [v6.x of the MongoDB Node driver](https://github.com/mongodb/node-mongodb-native/releases/tag/v6.0.0).
 There's a few noteable changes in MongoDB Node driver v6 that affect Mongoose:
 
 1. The `ObjectId` constructor no longer accepts strings of length 12. In Mongoose 7, `new mongoose.Types.ObjectId('12charstring')` was perfectly valid. In Mongoose 8, `new mongoose.Types.ObjectId('12charstring')` throws an error.
