MongoDB has updated its officially supported drivers to introduce new error checking and reporting defaults, aiming to provide a more intuitive experience for users. The previous default behavior, which did not wait for a database response by default, caused confusion among MongoDB users. To rectify this, the new version will have a top-level connection class in each driver that maintains the old default, but becomes deprecated. For new code, the `MongoClient` class is introduced, which defaults to a WriteConcern of 1 and provides a more intuitive experience for users. The update aims to provide better error handling and reporting, while minimizing disruption to existing MongoDB applications.
