MongoDB Node.js Driver 4.2.1 Released

The MongoDB Node.js team is pleased to announce version 4.2.1 of the mongodb package!

Release Highlights

This release fixes an issue with the dbName being overridden by the authSource option. Additionally, we have ensured that cursors re-run server selection when fetching additional batches, which should reduce issues encountered in long running function as a service environments.
