What's New in Joomla! 2.5?

sample-04As with previous releases, Joomla! provides a unified and easy-to-use framework for delivering content for Web sites of all kinds. To support the changing nature of the Internet and emerging Web technologies. Joomla! 2.5 has many new features.

When you already upgraded your site from Joomla! 1.5 to Joomla! 1.7 in 2011 you probably use all the new features introduced with Joomla! 1.6 and 1.7. When you scroll down and read the list of new features compared to Joomla! 1.5 then you realize that 2011 was a very interesting year for Joomla!.

But let's have a closer look on the new features for Joomla! 2.5.

New Features in Joomla! 2.5

The shiny new Joomla! Platform

The Joomla Platform Version 11.3 is now the base of the CMS.
That means many more possibilities for third party developers e.g. image manipulation with the JImage class and generation of HTML tables with the JGrid class. A new version of the JavaScript library MooTools is used (1.4). If you don't know what Joomla! platform is about, read Write your own App using Joomla! Platform  and the official annoucement of the Joomla Platform release.

Find more content with Smart Search

Search is "reinvented" in Joomla! 2.5 with Finder. The new finder component works with a search index (Figure 1).

Finder pre-searches your content. Search results are scored dynamically based on the context and frequency of search terms. The most relevant content will always be listed at the top of the results. It suggests alternative phrases (Figure 2) and its pluggable adapter system allows to install new search adapters which provide support for standard Joomla! content and many other types of documents. Custom search filters allows you to provide contextual searching when your visitor is looking at particular sections of your Web site.

Spread Joomla! to more Platforms by using more Databases

With Joomla! 2.5 it will be possible to run Joomla! on MySQL and Microsoft SQL Server. Drivers for PostgreSQL and Oracle seems to be very near (Getting Ready for Multi-Database Support).

Better Choices for Offline Mode

You can user the default offline message, disable it or create a customized message. Additionally you can select an image for the offline mode page (Figure 3). You have even a possibility to set the site to offline mode during installation so no unauthorized people can see it before you want them to.

User registrations with CAPTCHA

A CAPTCHA plugin using the reCAPTCHA service can be enabled (Figure 4). Once you sign up for free with reCAPTCHA and enter your keys, you can enable CAPTCHA on new user registrations. It could also be used by other extensions needing CAPTCHA.

Easier handling for simple Layouts

You can now attach an image for the intro text to use in blog and featured layouts, an image for the full article text and up to three links for the full
article layout. This means that your content creators won’t have to fuss with an image in the text and your article format will be cleaner and more consistent.


The Beez core template comes with mobile enhancements.


You can override the default language strings in a new manager in the backend (Figure 5).

User Notes

User Notes can be attach notes to users as well as assign tracking dates to the users. You can have multiple notes per user and the notes can be in different categories (Figure 6).

Clean Up

Filtering for Categories in Article Manager

That is simply useful. Since Joomla! 1.6 it was possible to filter categories in the article manager, but you did not see the articles of the subcategories. Now the filter logic include the articles of the subcategories too.

Linking New Menus with a Module

In Joomla! 2.5 modules are NOT automatically created for each new menu type. This is not a bug, it's a feature :)
Not everyone used the core menu module, but used instead ones from a custom template or third party module. For that reason, menus did not automatically create a module in 1.6/1.7. This change confused people and created extra work. In Joomla 2.5, if there is no module associated with the menu, there is a link showing in the Menu Manager that you can click that will take you directly into a new module that you can create. You then have the choice of saving this standard menu module or cancelling out and using a different menu module.

Custom Text Filters are moved to the global configuration. They are filtering content for black and white listed tags based on your configuration and on role permission.

You can now choose to have the administrator get a new message when a user creates an account. This is useful when the New User Account Notification is set to Self. In that case the user receives after an email after registration with an activation link (Figure 7). After clicking that link the account is activated.

The extensive options in “Select a Menu Item Type” are not loaded unless you need them.

New Features compared to Joomla! 1.5

In comparison to Joomla! 1.5 the differences are huge and there is a long list of features and improvements.

Here is a list of the most important changes in Joomla 1.6 and 1.7

  • There will no longer be any sections. Categories can be nested as deeply as you would like
  • The access concept is totally rebuilt.
    The existing user groups used in Joomla! 1.5 are still the same in Joomla! 2.5 but they can be enhanced and renamed. Unlimited access levels can also be defined there. User groups can be assigned to access levels and different groups can then be assigned to various access levels.
  • Multiprocessing
    Copy and move operations, and the allocation of access levels can now be done in a batch process
  • Updates per mouse click
    A simple feature. The system detects available updates and initiates them by clicking on the corresponding button.
  • Templates
    There have been many changes in the area of templates. There are now two administrator templates and three website templates.
  • Template styles
    Sometimes you may want to display a template with different options. You may want to create a page with a red background and another page with a blue one. Therefore, you will need template styles. Create as many versions (styles) of a template with different settings as you like and assign them to a menu link.
  • Template layouts
    Sometimes you may want to display only the output of a component or a module in a different layout without hacking the template. That's possible with template layouts.
  • Consistent user interface
    A successful example is the general save dialogue.
    Save: content will be saved, you remain in editing mode
    Save & Close: content will be saved, you leave the editing mode
    Save & New: content will be saved; a new, empty editing mask appears
    Save as copy: content will be saved as a copy, you remain in the editing mask
  • Minimum requirements
    The minimum requirements regarding your server environment and concerning your visitors' web browsers have increased.
    Browser: Internet Explorer, version 7 or higher, Firefox, version 3 or higher, Safari, version 4 or higher
    Server: PHP: minimum version PHP 5.2.4, MySQL: minimum version 5.04
  • Legacy Mode
    The legacy mode from Joomla! 1.5 is no longer necessary. Legacy mode allowed the execution of components originally developed for Joomla 1.0, which have 'only' been adapted to Joomla! 1.5. The procedure of adapting old components is offset by the development of 'native' Joomla! 1.5 and 2.5 components, which use the Joomla! Framework.
  • Search engine optimization
    • You can now use unicode in URLs, which means you may now use special characters like 'ö' and 'ä' or Arabic or Hebrew characters in the URL.
    • You can allocate meta text and keywords to categories.
    • A title of a site will be displayed following the name of the website in the browser.
  • Modules can be published time-controlled. The assignment options to menu items have been extended.
  • Multilingualism
    Joomla! core now offers the possibility to create articles, categories and modules in several languages. With the new language switcher plug-in module you can filter the entire site for the selected language.
  • New editor
    Code Mirror is the new editor, which is supplied in addition to TinyMCE. It is not a WYSIWYG editor but offers a convenient way to work with 'code-like' content, which will be displayed in colour and a structured way.
  • Components
    • The new redirect component enables redirections to URLs in order to avoid '404 not found' errors.
    • The new search component provides an overview of the searched keywords and display results.
    • The survey component has been eliminated.
  • New Release Cycle
    Every 18 months, a long term release of Joomla! will appear.
  • Introduction of the Joomla! platform
    Joomla! consists of two parts
    • the Joomla! platform
    • the Joomla! content management system

There are many more very nice little features like the possibility to place a background image into a module or to display articles with page breaks in a tab or slider layout.
