Next week KDE will release Applications 19.04, overhauling most of the suite of programs usually packaged with KDE's Plasma desktop. This new version makes KDE's applications more user-friendly, consistent with each other and smoother across the board.

Okular gets, among other improvements, support to show and verify digital signatures on PDFs. This feature is essential to use KDE's document viewer for business or if you need to exchange documents in any official capacity... like when negotiating an international peace treaty. Digital signatures allow you to establish the authenticity of a document, whether it has been tampered with or not, and confirm where it has come from and who sent it.
