The last (2004) revision of the style guidelines has been updated. This is not a major revision, and all the category and style names and numbers remain the same. Technically, this is the “2008 update to the 2004 guidelines” but will generally be known as the 2008 guidelines. The website navigation bar has been updated to point to the new version. See the one-page PDF summary of the changes, 2008: BJCP Style Guidelines Revision Summary.
