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,4.0
release series and4.2
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 and4.3
development series. Development series are for testing only and not for production.
For example, in MongoDB version 4.0.12
, 4.0
refers to the
release series and .12
refers to the revision.
New Releases
Changes in the release series (e.g. 4.0
to 4.2
) generally mark
the introduction of new features that may break backwards compatibility.
Patch Releases
Changes to the revision number (e.g. 4.0.11
to 4.0.12
)
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.
