This release adds support for PDF/A-4 (ISO 19005-4:2020) including core requirements, Level F (file attachments) and Level E (engineering). It also now supports Java versions from 8 to 16. To learn more about the new fixes and features read the release notes.
Internal testing of the release candidate is also being carried out and there may be a few small changes before the final production release.
Our thanks go to all contributors, particularly the Dual Lab development team, and the OPF Product Board.
