The MongoDB Node.js team has released version 3.3.0 of their driver, which includes support for MongoDB 4.2 servers, enabling features such as distributed transactions and retryable reads. The new driver also introduces an enhanced SRV polling mechanism for sharded clusters, allowing applications to automatically update their knowledge of the cluster's topology while running. Additionally, the internal structure of the driver has been simplified by merging the low-level mongodb-core with the high-level node-mongodb-native, which is expected to speed up development. The release notes and documentation provide more information on how to use the driver, including a full API reference and support for MongoDB 4.2 servers.
