Releases: mongodb/node-mongodb-native
v5.2.0
The MongoDB Node.js team is pleased to announce version 5.2.0 of the mongodb package!
Release Highlights
This release includes driver support for automatically obtaining Azure credentials when using automatic client side encryption. You can find a tutorial for using Azure and automatic encryption here: Use Automatic Queryable Encryption with Azure
Additionally, we have a number of minor bug fixes listed below.
NOTE: This release includes some experimental features that are not yet ready for use. As a reminder, anything marked experimental is not a part of the stable driver API and is subject to change without notice.

v5.1.0
The MongoDB Node.js team is pleased to announce version 5.1.0 of the mongodb package!
Release Highlights
Support for JavaScript bigints in the driver
The driver now supports automatic serialization of JavaScript bigints to BSON.Longs. It also supports deserializing of BSON.Long values returned from the server to bigint values when the useBigInt64 flag is passed as true.
import { MongoClient } from 'mongodb';
(async () => {
const client = new MongoClient('<YOUR CONNECTION STRING>');
const db = client.db('test');
const coll = db.collection('bigints');
await coll.insertOne({ a: 10n }); // The driver automatically serializes bigints to BSON.Long before being sent to the server
const docBigInt = await coll.findOne({ a: 10n }, { useBigInt64: true }); // Must provide the useBigInt64 flag to specify that bigints get returned
console.log(docBigInt);
// { _id: ObjectId(...), a: 10n }
const doc = await coll.findOne({ a: 10n }); // Must provide the useBigInt64 flag to specify that bigints get returned
console.log(doc);
// { _id: ObjectId(...), a: 10 }
await client.close();

v5.0.0

The MongoDB Node.js team is pleased to announce version 5.0.0 of the mongodb package!
Release Highlights
Node.js driver v5 emphazises the modernization of our API.
Farewell to Callbacks
Most notably, we have removed support for callbacks in favor of a Promise-only public API.
To ease the migration to a Promise-only approach when using the Node.js driver, callback support is available via the mongodb-legacy package. You can read more about this change in the Optional callback support migrated to mongodb-legacy section of the migration guide.
Dot Notation No Longer Enabled by Default
Version 4.3.0 of the Node.js driver introduced strict type checking on Filter queries that used dot notation. This functionality was enabled by default and proved to be a barrier for users upgrading to later versions of the Node.js v4.x driver. In order to ease the migration to v5.0.0, type strictness on queries that use dot notation has been removed from the CRUD API. The type checking capabilities are still available in an experimental type called StrictFilter. You can read more about this change in the Dot Notation TypeScript Support Removed By Default section of the migration guide.
BSON v5
This release also adopts all the changes in BSON v5.0.0 (see the release notes).
The driver now exports a BSON namespace that also has BSON.EJSON APIs available.
When working in projects where both the driver and bson are used, we recommend importing BSON types (ObjectId, Long, etc.) and BSON APIs from the driver instead of from BSON directly to ensure consistency when serializing and deserializing instances of the BSON types.
Other Notable Changes
@aws-sdk/credential-providers has now been moved to an optional peer dependency.
Consequently, in v5.0.0 or later versions of the driver, the AWS credential provider module must be installed manually to enable the use of the native AWS SDK for authentication.
Collection.insert, Collection.update, and Collection.remove methods have been removed in favor of their non-deprecated counterparts. You can read more about this and other changes in our Driver v5 Migration Guide.

Release Highlights
ChangeStreams are now AsyncIterators
ChangeStreams are now async iterables and can be used anywhere that expects an async iterable. Notably, change streams can now be used in Javascript for-await loops:
const changeStream = collection.watch();
for await (const change of changeStream) {
console.log(“Received change: “, change);
}Some users may have been using change streams in for-await loops manually by using a for-await loop with the ChangeStream’s internal cursor. For example:
const changeStream = collection.watch();
for await (const change of changeStream.cursor) {
console.log(“Received change: “, change);
}The change stream cursor has no support for resumabilty and consequently the change stream will never attempt to resume on any errors. We strongly caution against using a change stream cursor as an async iterable and strongly recommend using the change stream directly.
Server Monitoring Fix When Monitoring Events are Skipped
Version 4.7.0 of the Node driver released an improvement to our server monitoring in FAAS environments by allowing the driver to skip monitoring events if there were more than one monitoring events in the queue when the monitoring code restarted. When skipping monitoring events that contained a topology change, the driver would incorrectly fail to update its view of the topology.
Version 4.12.0 fixes this issue by ensuring that the topology is always updated when monitoring events are processed.
Performance Improvements with Buffering
This release also modifies the data structures used internally in the driver to use linked lists in places where random access is not required and constant time insertion and deletion is beneficial.
External Contributions
Many thanks to @ImRodry for helping us fix the documentation for our deprecated callback overloads in this release!
