2003年5年28日（北京时间），WordPress创始人 Matt Mullenweg（马特·穆伦维格）发布了WordPress第一个可用版本。
第一个WordPress版本：0.71-goldd的WordPress功能特征：
九年过去了，WordPress已经成为主流的网站发布系统平台，并在全球有超过2.5亿用户的使用量，官方插件19601个，下载：306,106,176次；主题：1514个，下载：49,066,756（截止到北京时间）。Texturize — So good it’ll make your quotes curl. WordPress Links — A link manager with everything you’d expect, from Weblogs.com support to a handy bookmarklet. Manage as many blogrolls as you like, and have complete control over their display. XHTML 1.1 — WordPress is complaint with XHTML standards up to 1.1, though by default it sends a 1.0 document type to avoid compatibility issues. Highly Intelligent Line Breaks — Occasionally called “nl2br on steroids,” this brand new function adds line breaks except where there is already a block level tag or another line break. New Administration Interface — We’ve made it as simple as possible, and no more. Everything has been restructured from the ground up in a fully compliant XHTML/CSS interface. Manual Excerpts — This allows you to handcraft summaries of your posts to appear in your RSS feed and other places. New Default Templates — Again we’ve streamlined theses with the latest in simple, easy-to-understand standard XHTML and CSS. And not a CSS hack in sight. Plus numerous behind the scenes code cleanups, making this release faster and more stable than ever.
