New features in OpenOffice 2.4

Although it is widely used, Adobe's Portable Document Format (PDF) is not a recognised ISO standard. Therefore, OpenOffice 2.4 has made it possible to export a document to the ISO-approved alternative, PDF/A. The benefit of this is primarily in archiving documents for future use, as there are several versions of PDF, as well as several options for it. 

In PDF/A, also known as ISO 19005-1, fonts have to be embedded, and audio, video and JavaScript are not allowed.
