Joomla! 2.5 is a new version of Joomla! base on Joomla! 1.7 with many changes and improvements. With Joomla 2.5 the user community placed a large emphasis on making the CMS installation process as simple as possible and new versions more frequent.


One Click Version Updating - Update a site to the latest stable Joomla release with just a click. The new built-in updater also handles updates for Joomla and Joomla extensions. This is a major enhancement improving upon the previous system of manually updating individual files on the server. 

Multilanguage Improvements - Multilanguage improvements allow you to associate menu items in different languages for faster navigation. Language packs can now also be built to automatically select the best font for that language for the administrative back end.

Additional features

  • The ability to create a search menu option with pre-defined search options. This allows developers to create a menu item that pre-fills out the search fields so end-users can have a built-in search for a specific phrase.
  • Better example code for different plug-in types. The enables developers to more easily build custom extensions.
  • The ability to automatically validate form data against a list of options during the save operation. This makes it easier to protect against hackers manipulating forms and trying to save invalid data.
  • Enables the submit article form to automatically set the article category. This makes it easier for site administrators to restrict users to a specific category meaning content isn't accidentally added to the incorrect page on a website.
  • Batch processing (copy & move) of articles is now available in the same way as it is for categories and menu items.
