Joomla! 3 is scheduled for launch in September.
There are the 3 things you need to know about Joomla 3:
What is great about Joomla 3? Mobile.
This is the version that will bring Joomla up-to-speed with the mobile revolution that is taking over the web.
Why is this valuable? It's predicted that, as soon next year, more people will be online via their phone than a desktop. The mobile version of your site may soon be more important than the desktop version.
Joomla 3 is using Bootstrap to make sure that the visitor and administrator areas are mobile-friendly.
Joomla will become the first major content management system to be 100% mobile-friendly by default.
Who is Joomla 3 for? Early adopters.
Initially, Joomla 3 is best used by early adopters, developers and more experienced users.
You will be able to build sites with Joomla 3 as soon as it is launched. However, as with the first release of most software, there's no need to rush in and use the first version.
I am on Joomla 2.5. What do I do? You can stay right where you are.
Joomla 2.5 is a wonderful version of Joomla and will be supported until 2014.
Will the upgrade be easy? Yes, the plan is to allow people to upgrade from 2.5 to 3 directly from the administrator area of their site. You will need to check that extensions and templates are ready for Joomla 3 before clicking the Update button. Remember though, you don't need to do that until 2013 or 2014.
If you are on Joomla 1.0 or 1.5, we do recommend that you upgrade to at least 2.5. Joomla 1.0 is 7 years old now and support has ended. Joomla 1.5 will be nearly 5 years old when support ends later this year.
