 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.

+   - `sslKey` -> `tlsCertificateKeyFile`
+   - `sslPass` -> `tlsCertificateKeyFilePassword`

 In Mongoose 7, `findOneAndRemove()` was an alias for `findOneAndDelete()` that Mongoose supported for backwards compatibility.
