We released MongoDB Server 4.0 for General Availability. The highlights of the release are:

Multi-document ACID transactions
The only open source data platform to combine the speed, flexibility, and power of the document model with ACID guarantees. It’s now even easier to address a complete range of use cases with MongoDB.

Type Conversions
Run sophisticated data transformations natively in the database to prepare for BI, machine learning, and more. Reduce your reliance on slow, costly, and fragile ETL processes.

Kubernetes Integration
The MongoDB Enterprise Kubernetes Operator allows you to leverage the automation, monitoring and backup capabilities of MongoDB Ops Manager to seamlessly deploy and manage your MongoDB workloads inside your Kubernetes OpenShift cluster.
