Every phpdocx version includes new features and improvements. Previously unsupported features may have been added to newer releases, or past issues may have been corrected.
I'm finding that the 300 MB OpenOffice directory in the lib folder really bloats the web folder. If a user-installed copy of OpenOffice is used, is the copy in the lib version required?
On that note, what folders are required for phpdocx versus optional?
You can use a custom installation of OpenOffice instead of the included one. And you can remove the lib/openoffice folder; be carefulto don't remove the other lib folders.
