If you are using the PDF viewer #Okular_from #Gpg4win, please upgrade to version 4.4.1 as this version fixes a severe vulnerability in the freetype library.

Vulnerability details:
https://euvd.enisa.europa.eu/enisa/EUVD-2025-6367 
There are other good things in Gpg4win 4.4.1, for example
* improvements in the Outlook Add-in (GpgOL)
* a better Kleopatra
* GnuPG upgraded to v2.4.8
Neue Version von #GnuPG (v2.5.6) und eine weitere Beta-Version des kommenden #Gpg4Win 5.0 erschienen.
Wer Gpg4Win (noch) nicht kennt: Enthält u.a. das MS Outlook-Plugin GpgOL damit dort #OpenPGP-verschlüsselte Mails funktionieren, GpgEX damit man im Explorer Dateien verschlüsseln kann, oder die Schlüssel-/Zertifikats-Verwaltung Kleopatra. Mit 5.0 dann Post Quanten resistant encryption.
S/MIME gibt es natürlich auch. Das skaliert wegen der Kosten für die zusätzlich zeitlimitierten Zertifikate, in der Bevölkerung aber noch schlechter als OpenPGP. Deshalb plädiere ich für einen Fokus darauf um wenigstens hier eine größere Verbreitung zu schaffen.
Und von mir ein fettes Danke an den Hauptentwickler der Werkzeuge @DD9JN
Hi!
A #GnuPG release (2.5.6) and a new #Gpg4win 5 beta is available since today:
https://lists.gnupg.org/pipermail/gnupg-announce/2025q2/000492.html
#gnupg 2.5.2 released; see https://lists.gnupg.org/pipermail/gnupg-announce/2024q4/000488.html
Also released a *beta* of #gpg4win 5 see https://www.gpg4win.org/version5.html
Better handling of certificates and public keys
with #Gpg4win v4.4.0's improved crypto manager _Kleopatra_.
It also comes with #GnuPG v2.4.7 for Windows. Workflows that profit from several signatures on a file
profit as well.
https://gpg4win.org/version4.4.html <-- see what else is new.
New versions of #gnupg (2.4.5) and #gpg4win (4.3.1) have been released. See https://lists.gnupg.org/pipermail/gnupg-announce/2024q1/000482.html
#Gpg4win v4.3.0 <- freshly announced.
New is that encrypted files with email structure from disk can be shown.
Kleopatra and the Outlook Add-in gain features and resilience for less common situations (like Apple mail attachments or unreliable S/MIME CRLs).
Includes #GnuPG v2.4.4 and its many improvements.

#GnuPG v2.4.4 is available and has a number of improvements for you, especially if you do your cryptography with "smartcards" like yubi-keys. Most important is that a recent defect was fixed that could leave unprotected copies of a secret key on disk. 
Also more cards are supported and getting pubkeys is improved. See
https://lists.gnupg.org/pipermail/gnupg-announce/2024q1/000481.html (Which links the #Gpg4win v4.3.0 download before the webside does.

The new #Gpg4win forum is waiting for you!

Look at https://gpg4win.org/version4.2.html to see why freshly released #Gpg4win 4.2.0 makes a difference: Includes an experimental, lightweight PDF reader geared towards secure environments.(To use the validation and signing abilities of the included PDF Reader #Okular by #KDE today, you'd probably need to be an expert to configure the certs. Usability is planned to improve with later releases). Gpg4win is faster for large files and with many public keys. #GnuPG 2.4.3 included. #EndtoEndCrypto #OpenPGP
#GnuPG version 2.4.2 is here, operating faster on Windows and bringing a handful of minor improvements. A #Gpg4win release with it, shall follow shortly. https://lists.gnupg.org/pipermail/gnupg-announce/2023q2/000479.html #end2endcrypto for files and email. #OpenPGP #FreeSoftware
Today it is to celebrate 25 years of #GnuPG a #FreeSoftware implementation of the '#OpenPGP and #CMS standards for #endtoendcrypto . For this GnuPG 2.4.0 is announced and #Gpg4win 4.1.0, see https://lists.gnupg.org/pipermail/gnupg-announce/2022q4/000477.html and https://lists.wald.intevation.org/pipermail/gpg4win-announce/2022/000099.html
