Joomla 2.5, due out in January 2012, will have a host of new features including new search functionality, multi-database support, and update notification. The following article describes these features. Many people in the community have contributed to making these features possible, some of whom are listed here. Moving from 1.7 to 2.5 can be done with the one-click upgrade within Joomla and most extensions that run on 1.7 should also run on 2.5.

New Search Function

Based on Finder, which was developed by jXtended, Joomla 2.5 has added an exciting new natural language search function. This feature incorporated auto-completion and stemming. Stemming is the ability for the search to use the root of the word you entered to locate matches. While there is still work to be done, this search is also much better at searching in languages other than English.

This new search is faster and more versatile that the standard search. The data is indexed to get this flexibility and speed. New plugins are required to use this search. Joomla ships with the new core extension plugins, but other extension developers will need to create their own plugins to work with this new search. By default, the standard search is active and this new search is disabled. You can enable the plugin and index your files when the extensions you want to search have the new plugins.

Ability to Support Other Databases

Joomla has traditionally run on the MySQL database. If your company has a different type of SQL database, such as MS SQL, then you'd have to make changes to the Joomla software to make it work, which makes updating difficult. Joomla has been rewritten so that different drivers can be written for different versions of SQL databases. Current drivers exist for the MySQL and MS SQL databases, with PostgreSQL, Oracle, SQLite and PDO drivers close to being ready.

Joomla Update Notification

The number one request from was for Joomla to tell the site administrator when Joomla needs to be updated. Site administrators will now be able to see as soon as they log in if Joomla is out of date. They can then click the button and be taken to the one-click update to Joomla. A second icon does the same thing for any non-core components that are set up for the one-click updating by their developers.

Database Version Fix Button

A new feature was added that will check to see that your database is up-to-date with any database schema changes added during upgrades. If they are out of date, you can press the Fix button to apply the needed changes. This is important for those people who are used to updating releases the 1.5 way by FTPing up the release files. Since FTPing cannot apply database changes, those people would have to apply the database changes manually. Not everyone has the access or the knowledge to make those changes. With this improvement, you just need to go to Extensions/Installation/Database and hit the Fix button. If you use the Update feature in Extensions/Installation/Update or install the upgrade in Extensions/Installation, you won't need this feature.

CAPTCHA uses scrambled text to prevent robotic spammers from submitting forms. Joomla 2.5 gains an API that lets you use CAPTCHAs in your forms. The core comes with a a plug-in that gives you the ability to use reCAPTCHA, the most accessible of the CAPTCHA services. 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. CAPTCHA has been available in non-core extensions, but this enables the feature in core.

Other plug-ins can be created by the the developer community and will work with all forms without modifying them.

Linking New Menus with a Module

Modules were automatically created for each new menu type  in Joomla 1.5. However, not everyone used the core menu module, but used instead ones from custom templates or non-core modules. 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.

Use the Images and URL Fields to Create Simple Standardized Layouts

In 2.5 you can choose to use the existing image and URL fields in the articles to set up a simple standardized layout for blogs, news reports, etc. These are fields that existed in the database but were never used. After you activate the feature in the Article Options Editing Layouts, you will be able to specify an image for the introduction and an image for the full article, as well as 3 links. This means that your content creators won't have to fuss with an image in the text (you can even disable the image button in the editor) and your article format will be cleaner and more consistent. You can use css, layout over rides and alternative layouts to customize your pages even further.  This feature also allows easy customization of the back end article editor to limit content creator and content editor options, for example removing the ability to change the images or publishing options.

Choose whether Administrator to Get Email When New Users Register

Menu Item Note

In 1.7 you had the ability to add a note to modules to remind you what the module was for. This feature adds that ability to menu items. You can use it, for example, to identify the menu item, clarify how it is used, or why it was set up the way it was.

Custom Text Filters

The Text filtering done automatically by Joomla when a user enters text has moved from its hiding place in the Articles Options to Global Configuration. This is appropriate since it covers all the components, not just articles.

Even better, you are now able to create your own custom blacklists. Blacklists are easier to manage than a whitelist because blacklists contain only the forbidden tags and attributes. In 1.7, you either used the default blacklist or you resorted  a whitelist where you had to type in all the possible tags and attributes that were allowed.

You can also use User Groups to give certain people permission to use a tag/attribute on the blacklist. Just create a User Group for, say, the people who can use iframe. In the Text Filter specify that User Group as whitelisted with iframe in the tag list. If you want to let someone use iframes, just add them to that new User Group.

In addition to the filtering done by Joomla (which covers all input forms), your chosen editor may have its own filtering process as well. For something to be allowed, it must get past both the Joomla text filtering, if any, and the editor filtering, if any.

Greater Flexibility Filtering by Category in Article Manager

In 1.7 when looking at articles you could filter by category. However, you didn't have a way of selecting a category and getting all the articles that are in that category and its subcategories. In 2.5, selecting a category in the articles manager will include its subcategories, down to the depth you select. If you only want the single category, you can select a level of 1.

Manager for Language Overrides

In 1.7 you could add overrides to language files to change the text. So if you wanted to change a label, message, or tooltip, you could put the language key in a text file in the right spot with the right name with the wording you wanted, once you figured out what the language key was. This was an improvement from 1.5 where you had to hack core.

With this new feature you can make these changes in the familiar backend of Joomla instead of putting on a programmer's hat. You search for the text that you see and get a list of language keys and text for you to select. You can then change what you want and save it. Want to add your Company's name to the email that goes out with the Forgot Your Password email? This is where you would do it.

User Notes

Now you can attach notes to users as well as assign dates to the users. These manual dates can be used for whatever you want, whether it's a date for reviewing the user, the last date you reviewed a user or for something entirely different. You can change the label for the date using the Language Overrides. You can have multiple notes per user and the notes can be in different categories.

Flexible Newsfeed Order

This feature makes it possible to reverse the order of the feed items. You can choose to display either the most recent first or the oldest first.

Image Option for the Offline Page

Joomla has always displayed a big Joomla logo when you put a site offline. This leads to confusion on whose site it is. In order to fix it, you had to provide a custom file in your template. With this feature, no image is displayed by default and you can upload/select any image you want to be displayed went your system is offline.

Option to Have a Site Come Up Offline After Installation

Before, when you installed Joomla it was automatically online as soon as it was installed. With this feature you have the option of having it come up offline so no unauthorized people can see it before you want them to.

Check for Native ZIP Support During the Installation

This feature adds a check during install to let you know if you have native ZIP enabled on your host. Native ZIP is recommended because it is much faster than using PHP to unzip. The slower speed of using PHP unzip could result in timeouts when you install large extensions or updates.

Debug Plugin Gets Formatting

When developers turn on the debug function, Joomla spits out various and, sometimes voluminous, amounts of unformatted data. This feature formats the different groups of data into sliders and color highlights the database queries. This works in both the frontend and the backend.

A True Autoloader for the CMS

With the Joomla Platform as a separate entity, the CMS needed a place to put files/classes that are universal to the CMS but not a part of the platform. With this autoloader, developers don't need to worry whether the class they need is in the platform files (libraries/joomla) or in the cms files (libraries/cms).
