You can experience MongoDB 4.2 Beta on Atlas without local setup or configuration by selecting MongoDB 4.2 Beta when creating an Atlas M10 cluster or larger. The beta release is available for paid clusters and includes features such as Wildcard Indexes, On-Demand Materialized Views, Expressive Updates, new aggregation stages and operators. Note that the Atlas MongoDB 4.2 Beta is not meant for production use, even if it offers exciting new features. To enable everyone to try out the beta, a coupon code MONGODB4DOT2 is available, which grants $200 Atlas credits. Overcoming weeks, various resources, including blog posts and free courses, will be made available to help users explore the capabilities of MongoDB 4.2 Beta.
