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
Yis even,X.Yrefers to a release series; for example,3.6release series and4.0release series. Release series are stable and suitable for production. - If
Yis odd,X.Yrefers to a development series; for example,4.1development series and4.3development 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.
