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.
Current Development Planning
Joomla! 1.6 is in the earliest stages of the Alpha Phase.
Joomla! 2.0 is also in the earlier stages but represents a significant change to the whole Joomla! concept.
You can keep up-to-date on developments on these two areas within the Joomla! Developer Network and in
the Joomla! Forums.
