WordPress is web software you can use to create a beautiful website or blog. WordPress is both free and priceless at the same time. WordPress was born out of a desire for an elegant, well-architectured personal publishing system built on PHP and MySQL and licensed under the GPLv2 (or later). It is the official successor of b2/cafelog. WordPress is fresh software, but its roots and development go back to 2001. It is a mature and stable product.
What's new in WordPress 3.5:
If you’ve been around WordPress a while, the most dramatic new change you’ll notice is a completely re-imagined flow for uploading photos and creating galleries. WordPress 3.5 includes a new default theme, Twenty Twelve, which has a very clean mobile-first responsive design and works fantastic as a base for a CMS site. Finally a lot of time was spent refreshing the styles of the dashboard, updating everything to be Retina-ready with beautiful high resolution graphics, a new color picker, and streamlining a couple of fewer-used sections of the admin.
