Version Convention

Joomla! release versioning follows a numerical convention comprised of three numbers: Major, Minor and Maintenance.  The version is presented in the major.minor[.maintenance] format.

Major Release Number (X.1.1)

An increment of the major number generally indicates a major rework or rewrite of the code base.

May be completely incompatible with prior major releases.

Minor Release Number (1.X.1)

An increment of the minor number usually indicates a significant change to functionality or architecture.

Moderate to high level of backward compatibility with previous minor increments.

Maintenance Release Number(1.1.X)

An increment of the maintenance number usually indicates bug fixing within the minor release and possibly small enhancements and limited new features.
