MongoDB Version Numbers¶
2.4 refers to the release series and
to the revision. The second component of the release series (e.g.
2.4.1) describes the type of release series. Release series ending
with even numbers (e.g.
4 above) are stable and ready for
production, while odd numbers are for development and testing only.
Generally, changes in the release series (e.g.
mark the introduction of new features that may break backwards
compatibility. Changes to the revision number mark the release bug
fixes and backwards-compatible changes.
Always upgrade to the latest stable revision of your release series.
The version numbering system for MongoDB differs from the system used for the MongoDB drivers. Drivers use only the first number to indicate a major version. For details, see Driver Version Numbers.
