I'm thoroughly enjoying your newest PDF24 edition 8.7. Thank you!
May I submit another feature request? PDF24 can currently output to PDF formats 1.2 to 1.7. I look forward to working with PDF 2.0 format -- which I believe was established by ISO in 2017. Format 2.0 provides a more secure treatment of AES-256 encryption than format 1.7 (already deprecated by ISO due to internal flaw). Hope to see this option in PDF24 soon. Thanks.
