@GnuPG @todd_a_jacobs @letsencrypt #GnuPG itself has improved its capabilities and squashed a number of bugs in the last four years. You can see from the commit history of the #ObjectivePGP library used by #PGPro that there were some substantive changes and important fixes in that library since the last release of the app. On #iOS, such libraries need to be compiled into the app signed by Apple, so none of those changes are in the App Store version.
