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。
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 youlike, 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 isalready 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 afully 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 hackin sight.Plus numerous behind the scenes code cleanups, making this release faster and more stable than ever.
