Breaking Changes

MongoDB Driver Upgrades

If you're using MongoDB 3.6 or earlier, install the new legacy package:

bash
meteor add npm-mongo-legacy

This will pin the MongoDB driver to 6.9.0 for compatibility.

If you’re on MongoDB 4+, the default MongoDB driver 6.16.0 is applied automatically.

Please migrate your database as soon as possible to MongoDB 5 onward, as MongoDB driver 6.17.0 will drop MongoDB 4 support. We’ll keep offering npm-mongo-legacy so you can keep getting Meteor updates with your existing MongoDB legacy version.

Cordova Upgrade

The Cordova platform has been upgraded to version 14. Refer to the Cordova Changelog for more details on the changes and migration steps.

Migration Steps

Please run the following command to update your project:

bash
meteor update --release 3.3.1

While this is a patch release, Meteor 3.3, a recent minor update, introduced a modern build stack that’s now the default for new apps. Here’s how you can migrate to it.

Add this to your package.json to enable the new modern build stack:

json
"meteor": {
  "modern": true
}

Check the docs for help with the SWC migration, especially if your project uses many Babel plugins.
