MongoDB Versioning

Important

Always upgrade to the latest stable revision of your release series.

MongoDB versioning has the form X.Y.Z where X.Y refers to either a release series or development series and Z refers to the revision/patch number.

  • If Y is even, X.Y refers to a release series; for example, 3.6 release series and 4.0 release series. Release series are stable and suitable for production.

  • If Y is odd, X.Y refers to a development series; for example, 4.1 development series and 4.3 development series. Development series are for testing only and not for production .

For example, in MongoDB version 3.6.14 , 3.6 refers to the release series and .14 refers to the revision.

New Releases

Changes in the release series (e.g. 3.4 to 3.6 ) generally mark the introduction of new features that may break backwards compatibility.

Patch Releases

Changes to the revision number (e.g. 3.6.13 to 3.6.14 ) generally mark the release of bug fixes and backwards-compatible changes.

Driver Versions

The version numbering system for MongoDB differs from the system used for the MongoDB drivers.
