WordPress is a personal publishing platform with a focus on aesthetics, Web standards, and usability. WordPress was born out of a desire for an elegant, well-structured personal publishing system built on PHP and MySQL and licensed under the GPL. 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. We hope by focusing on user experience and web standards we can create a tool different from anything else out there.
What's new in this version:
Version 3.6 includes new Twenty Thirteen theme, built-in HTML5 media player, and better filters for how revisions work, so you can store a different amount of history for different post types.
