This category is a list pages and subcategories of what is Version Changes or Enhancements.
Please read the Release and support cycle for Joomla!. The article will help you understand the differences in a STS (Short Term Support), and LTS (Long Term Support) Joomla! CMS release and the differences in what version might be a better choice to use.
Please note that both STS and LTS releases, once they have reached the GA (General Availability) status, are fully functional and ready to be used in production environment. The disadvantage of using STS releases is that you will need to update your installation of Joomla! every six months, while the advantage is that you will have access to new features and extensions earlier.
