  • Database Commands
  • Aggregation

This page contains a changelog of the Stable API. The Stable API is actively being expanded to include new database commands and functionality.

The commands and operators included in the Stable API depend on the MongoDB version you are using. This page describes the MongoDB and Stable API versions when a database command or specific sub-features of a command are available.
