Atlantis Word Processor 18.104.22.168 has been released for betatesting. It includes a number of changes to its "Save as eBook" feature. Page breaks from source documents are now saved to EPUBs differently. Page margins of eBooks can now be controlled through the GUI of Atlantis. Generic font families (or basic fallback fonts) are now automatically saved to EPUBs. Plus there are a few bug fixes.
