Is Digital Editions compatible with Acrobat 8?
Yes. Acrobat 8 supports creating content that conforms to the PDF/A profile. PDF/A documents work with Digital Editions, as well as with Acrobat and Reader. However, Acrobat 8 and Reader 8 no longer directly support the Adobe Content Server eBook DRM solution. Instead, they rely on integration with Digital Editions to enable users to view PDF files protected by Adobe Content Server, including documents protected with the new Adobe Digital Experience Production Technology (ADEPT) content protection service.
