New output formats: XHTML 5, Web Help containing XHTML 5,
EPUB 3, possibly containing rich media.

A new chapter of the manual, "Rich media content",
http://www.xmlmind.com/ditac/_distrib/doc/manual/webhelp/media.html,
explains how to add SVG, MathML, audio, video, Flash animations and
actions (e.g. click some text to play a sound) to your
DITA topics. This chapter also explains how XMLmind DITA Converter
processes this rich media content depending on whether it is
supported by the output format.

The DITA 1.2 Specification is now available online in WebHelp format using SuiteHelp. 

This is a useful online resource, as it includes advanced search capability (phrase search, fuzzy search, prefix, NEAR, Boolean, etc.) and also showcases a mobile-friendly platform to publish DITA XML with or without the DITA Toolkit.   http://ditaspec.suite-sol.com
