Why upgrade to MongoDB 4.0? There are several reasons to keep upgrading MongoDB. Newest version offers multiple new features, fixes previous version bugs/ issues, and improves security.

MongoDB 4.0 has been available for download since June 27, 2018. The new release offers new features designed to help you work with data, helping you place it anywhere you need it.

Feature highlights include:


If you’re using an older version of MongoDB, you must successively upgrade to MongoDB 3.6 before moving to 4.0.
If your deployment has user credentials stored in MONGODB-CR schema, upgrade to Salted Challenge Response Authentication Mechanism (SCRAM) before moving to MongoDB 4.0.
Starting in version 4.0, MongoDB removes support for the $isolated operator. Before upgrading you need to recreate the index or views without $isolated operator.
The 3.6 instance must have feature Compatibility Version set to 3.6.
