History

b2\cafelog, more commonly known as simply b2 or cafelog, was the precursor to WordPress. b2\cafelog was estimated to have been employed on approximately 2,000 blogs as of May 2003. It was written in PHP for use with MySQL by Michel Valdrighi, who is now a contributing developer to WordPress. Though WordPress is the official successor, another project, b2evolution, is also in active development.

WordPress first appeared in 2003 as a joint effort between Matt Mullenweg and Mike Little to create a fork of b2.

In 2004 the licensing terms for the competing Movable Type package were changed by Six Apart, and many of its users migrated to WordPress – causing a marked and continuing growth in WordPress's popularity.

In 2007 WordPress won a Packt Open Source CMS Award.

Releases

WordPress releases are named after well-known jazz musicians. For example, WordPress 1.2 was code named Mingus (after Charles Mingus).

WordPress 1.5 was released mid-February 2005 and code named Strayhorn. It added a range of new vital features. One such is being able to manage static pages. This allows content pages to be created and managed outside the normal blog chronology and has been the first step away from being simple blog management software to becoming a full content management system. Another is the new template/theme system, which allows users to easily activate and deactivate "skins" for their sites. WordPress was also equipped with a new default template (code named Kubrick) designed by Michael Heilemann.

WordPress 2.0 was released in December 2005 and code named Duke. This version added rich editing, better administration tools, image uploading, faster posting, an improved import system, and completely overhauled the back end. WordPress 2.0 also offered various improvements to plugin developers.
