- **changed** — Bump maxWireVersion to 29 in preparation for MongoDB LTS v9.0
- **fixed** — Fix SCRAM authentication for non-Node.js runtimes such as Deno by using explicit UTF-8 string conversion instead of implicit toString() calls on byte arrays

> [!IMPORTANT]
> A future minor release will raise the minimum supported MongoDB Server version from 4.2 to 4.4. This is in accordance with [MongoDB Software Lifecycle Schedules](https://www.mongodb.com/legal/support-policy/lifecycles). Support for MongoDB Server 4.2 will be dropped in a future release!

##### [7.3.0](https://github.com/mongodb/node-mongodb-native/compare/v7.2.0...v7.3.0) (2026-06-04)

The MongoDB Node.js team is pleased to announce version 7.3.0 of the `mongodb` package!

##### Release Notes



###### `maxWireVersion` is bumped to `29`

Max wire version & max server version bumped in preparation for MongoDB LTS (v9.0).

###### Fixed SCRAM authentication for non-Node.js runtimes (e.g., Deno)

SCRAM-based authentication (the default mechanism for username/password connections) was broken when using the driver in non-Node.js environments such as Deno. The root cause was an implicit `toString()` call on byte arrays that produced incorrect output outside of Node.js. This fix ensures explicit UTF-8 string conversion is used throughout the SCRAM implementation, restoring authentication in Deno and other web-compatible runtimes.

###### Features

* **NODE-7518:** bump maxWireVersion ([#4950](https://github.com/mongodb/node-mongodb-native/issues/4950)) ([4447050](https://github.com/mongodb/node-mongodb-native/commit/444705061ae49973a432fbcb0098419b72b75409))


###### Bug Fixes

* **NODE-7548:** SCRAM authentication fails on non-Node runtimes ([#4932](https://github.com/mongodb/node-mongodb-native/issues/4932)) ([a10d2c9](https://github.com/mongodb/node-mongodb-native/commit/a10d2c937eaa2bfb30aece513c9770ec55541280))
