Internal API changes ​

N/A

Migration Steps ​

Please run the following command to update your project:

bash

meteor update --release 3.1

Make sure to migrate userland code to use the new Express APIs:

https://expressjs.com/en/guide/migrating-5.html

The MongoDB Node.js driver implemented a significant breaking change regarding operation handling. Applications leveraging rawCollection() or rawDatabase() methods must now utilize Promise-based syntax exclusively, as the callback-pattern API has been deprecated and removed. This modification affects all direct MongoDB operations previously using callback functions.
