ApsaraDB for MongoDB releases minor versions on a regular basis to add features and fix known issues.

Check or upgrade the minor version

You can log on to the MongoDB console and view the current minor version in the Specification Information section on the Basic Information page of the target instance. In the Specification Information section, find the Minor Version field to view the minor version number of the instance, for example, 5.0.3-20211014145955_2.

To upgrade the minor version of an instance, see Upgrade the minor database version.
