release with many new features and improvements as briefly described
below. For a detailed list of changes, see

).
An update to this version is strongly recommended due to some security
fixes in
GnuPG
itself and in
Okular - GnuPG edition
Be aware that Gpg4win is now built natively for 64-Bit Windows. This
changes the path to the installation directory and Registry keys.
If 3rd party software on your system uses gpg, you might have to update the
path to the gpg binary in it's configuration.
32-Bit Windows is no longer supported.
Crypto Backend (GnuPG 2.5)
Update to the new stable version 2.5.16 with support for Post Quantum
Cryptography.
Crypto-Manager (Kleopatra)
Upgrade to Qt 6.10.1 and KDE Frameworks 6.20.
This upgrade from Qt 5
brings many improvements, including better dark mode support.
The notepad was redesigned and now opens in a separate window.
Many accessibility and UX improvements.
PDF-Viewer (Okular - GnuPG edition)
OpenPGP signature support is now available.
The signature workflow is improved.
Better visual representation of signatures.
New Outlook Plugin (GpgOL/Web)
Introduction of the new GpgOL/Web add-in, it is still
experimental
It was designed and implemented from scratch to support the new, web-based
Outlook. This add-in uses a locally running service to fetch and send
encrypted messages from/to Outlook. Therefore unencrypted content does not
leave the local operating system and is not synced to the cloud.
This add-in is still in development and missing features.
Classic Outlook Plugin (GpgOL)
Some fixes and adjustments to Outlook.
Note on compliance
The new version of the crypto backend is not yet approved for VS-NfD /
