Joomla 3.0 release is due in September,2012. Joomla Team is working hard to bring the new era of Joomla to life. One of the major change will be an overhaul change in look of Joomla’s design. Front end as well as backend administrator side will get a brand new look from top-to-bottom in Joomla 3.0.

The next web revolution will be the mobile revolution. As hundreds of millions more people come online, many of them will only be using mobile devices. Our aim is make Joomla 3.0 completely mobile-friendly, while still remaining recognizably Joomla.
