Joomla! 2.5 continues development of the Joomla Framework and CMS as a powerful and flexible way to bring your vision of the web to reality.
This is a module where you might want to add some more information or an image, a link to your social media presence, or whatever makes sense for your site.
You can edit this module in the module manager. Look for the Side Module.
The new user manager will let you manage who has access to what in your site. You can leave access groups exactly the way you had them in Joomla 1.5 or make them as complicated as you want. You can learn more about how access control works in on the Joomla! Documentation site
In Joomla 1.5 and 1.0 content was organized into sections and categories. From 1.6 forward sections are gone, and you can create categories within categories, going as deep as you want. The sample data provides many examples of the use of nested categories.
All layouts have been redesigned to improve accessibility and flexibility.
Updating your site and extensions when needed is easier than ever thanks to installer improvements.
