A new WordPress version 3.1.3 , a minor upgrade, was released yesterday (5/25/2011). Great job WordPress team. Keep up the good work. Thank you!
WordPress 3.1.3 was released on May 25th, and on May 31, when I tried to have a new installation of WordPress with Softaculous ( free service offered with Arvixe Hosting ), WordPress version 3.1.3 was already available! Meanwhile Fantastico's WordPress is still giving you online version 3.1 (Of course WordPress upgrade is easy with Arvixe Hosting server, but still that is extra clicks and some new WordPress users may not be aware of the necessity of upgrading to 3.1.3 in timely manner.
The bottom line is Softaculous WordPress auto installation is now more updated, easier and faster (one step compared to Fantastico three steps). Also it offers installation backup which Fantatico does not have.
