As DITA continues to grow in popularity, the standard has expanded to embrace more types of documentation. DITA 1.1 was ratified as standard in August 2007, superseding version 1.0 (ratified May 2005) of the standard. DITA News tracks DITA compatibility over seven categories of vendor products. In the category of “DITA XML CMS”, Astoria Software was the only vendor showing support for DITA 1.1 as of April 2008
