v7.7.0

on Node.js Yarn

7.7.0 (2026-09-28)

The MongoDB Node.js team is pleased to announce version 7.7.0 of the mongodb package!

Release Notes

OIDC authentication recovers from a failed token fetch

A single failed OIDC token fetch, such as a cloud metadata endpoint timing out, used to leave the driver's token-fetch mutex holding that failure. Every later operation on the affected MongoClient then failed with the original error without attempting a new token fetch, and only restarting the process restored authentication. A failed token fetch now affects only the operation that triggered it.
