How the PHP-Fusion versioning works.
PHP-Fusion Versioning Explained
Our versioning is not that complex as it may seem to be at a first glance. PHP-Fusion have 3 steps with more than enough possibilities for our needs. In PHP-Fusion 7 we have - 7.02.07, The 7 is the branch version. The .02 is the Major version within the 7 branch. The .07 is a Lesser version within the 7.02 branch.
A Branch version contains many significant features and functions not seen in the previous branch. A lot of documentation will be required for all the new features and functions introduced.
A Major version can contain larger functional changes that may have an impact on the system and it´s way to handle things. A Major upgrade may require that you also have some basic knowledge of the changes made, in order to make a safe transition from your previous version.
A Lesser version is not allowed to have any structural or functional changes. The upgrade need to be fairly simple.
